The Über-Lie

By Richard Heinberg, Post Carbon Institute

This is an excellent article from Richard Heinberg, the writer who sent me on my current life voyage all those years ago. Hot on the heels of my attempt yesterday of explaining where global politics are heading, Richard (whom I met years ago and even had a meal with…) does a better job than I could ever possibly muster.  Enjoy……

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Our new American president is famous for spinning whoppers. Falsehoods, fabrications, distortions, deceptions—they’re all in a day’s work. The result is an increasingly adversarial relationship between the administration and the press, which may in fact be the point of the exercise: as conservative commentators Scott McKay suggests in The American Spectator, “The hacks covering Trump are as lazy as they are partisan, so feeding them . . . manufactured controversies over [the size of] inaugural crowds is a guaranteed way of keeping them occupied while things of real substance are done.”

But are some matters of real substance (such as last week’s ban on entry by residents of seven Muslim-dominated nations) themselves being used to hide even deeper and more significant shifts in power and governance? Steve “I want to bring everything crashing down” Bannon, who has proclaimed himself an enemy of Washington’s political class, is a member of a small cabal (also including Trump, Stephen Miller, Reince Priebus, and Jared Kushner) that appears to be consolidating nearly complete federal governmental power, drafting executive orders, and formulating political strategy—all without paper trail or oversight of any kind. The more outrage and confusion they create, the more effective is their smokescreen for the dismantling of governmental norms and institutions.

There’s no point downplaying the seriousness of what is up. Some commentators are describing it as a coup d’etat in progress; there is definitely the potential for blood in the streets at some point.

Nevertheless, even as political events spiral toward (perhaps intended) chaos, I wish once again, as I’ve done countless times before, to point to a lie even bigger than the ones being served up by the new administration—one that predates the new presidency, but whose deconstruction is essential for understanding the dawning Trumpocene era. I’m referring to a lie that is leading us toward not just political violence but, potentially, much worse. It is an untruth that’s both durable and bipartisan; one that the business community, nearly all professional economists, and politicians around the globe reiterate ceaselessly. It is the lie that human society can continue growing its population and consumption levels indefinitely on our finite planet, and never suffer consequences.

Yes, this lie has been debunked periodically, starting decades ago. A discussion about planetary limits erupted into prominence in the 1970s and faded, yet has never really gone away. But now those limits are becoming less and less theoretical, more and more real. I would argue that the emergence of the Trump administration is a symptom of that shift from forecast to actuality.

Consider population. There were one billion of us on Planet Earth in 1800. Now there are 7.5 billion, all needing jobs, housing, food, and clothing. From time immemorial there were natural population checks—disease and famine. Bad things. But during the last century or so we defeated those population checks. Famines became rare and lots of diseases can now be cured. Modern agriculture grows food in astounding quantities. That’s all good (for people anyway—for ecosystems, not so much). But the result is that human population has grown with unprecedented speed.

Some say this is not a problem, because the rate of population growth is slowing: that rate was two percent per year in the 1960s; now it’s one percent. Yet because one percent of 7.5 billion is more than two percent of 3 billion (which was the world population in 1960), the actual number of people we’re now adding annually is the highest ever: over eighty million—the equivalent of Tokyo, New York, Mexico City, and London added together. Much of that population growth is occurring in countries that are already having a hard time taking care of their people. The result? Failed states, political unrest, and rivers of refugees.

Per capita consumption of just about everything also grew during past decades, and political and economic systems came to depend upon economic growth to provide returns on investments, expanding tax revenues, and positive poll numbers for politicians. Nearly all of that consumption growth depended on fossil fuels to provide energy for raw materials extraction, manufacturing, and transport. But fossil fuels are finite and by now we’ve used the best of them. We are not making the transition to alternative energy sources fast enough to avert crisis (if it is even possible for alternative energy sources to maintain current levels of production and transport). At the same time, we have depleted other essential resources, including topsoil, forests, minerals, and fish. As we extract and use resources, we create pollution—including greenhouse gasses, which cause climate change.

Depletion and pollution eventually act as a brake on further economic growth even in the wealthiest nations. Then, as the engine of the economy slows, workers find their incomes leveling off and declining—a phenomenon also related to the globalization of production, which elites have pursued in order to maximize profits.

Declining wages have resulted in the upwelling of anti-immigrant and anti-globalization sentiments among a large swath of the American populace, and those sentiments have in turn served up Donald Trump. Here we are. It’s perfectly understandable that people are angry and want change. Why not vote for a vain huckster who promises to “Make America Great Again”? However, unless we deal with deeper biophysical problems (population, consumption, depletion, and pollution), as well as the policies that elites have used to forestall the effects of economic contraction for themselves (globalization, financialization, automation, a massive increase in debt, and a resulting spike in economic inequality), America certainly won’t be “great again”; instead, we’ll just proceed through the five stages of collapse helpfully identified by Dmitry Orlov.

Rather than coming to grips with our society’s fundamental biophysical contradictions, we have clung to the convenient lies that markets will always provide, and that there are plenty of resources for as many humans as we can ever possibly want to crowd onto this little planet. And if people are struggling, that must be the fault of [insert preferred boogeyman or group here]. No doubt many people will continue adhering to these lies even as the evidence around us increasingly shows that modern industrial society has already entered a trajectory of decline.

While Trump is a symptom of both the end of economic growth and of the denial of that new reality, events didn’t have to flow in his direction. Liberals could have taken up the issues of declining wages and globalization (as Bernie Sanders did) and even immigration reform. For example, Colin Hines, former head of Greenpeace’s International Economics Unit and author of Localization: A Global Manifesto, has just released a new book, Progressive Protectionism, in which he argues that “We must make the progressive case for controlling our borders, and restricting not just migration but the free movement of goods, services and capital where it threatens environment, wellbeing and social cohesion.”

But instead of well-thought out policies tackling the extremely complex issues of global trade, immigration, and living wages, we have hastily written executive orders that upend the lives of innocents. Two teams (liberal and conservative) are lined up on the national playing field, with positions on all significant issues divvied up between them. As the heat of tempers rises, our options are narrowed to choosing which team to cheer for; there is no time to question our own team’s issues. That’s just one of the downsides of increasing political polarization—which Trump is exacerbating dramatically.

Just as Team Trump covers its actions with a smokescreen of controversial falsehoods, our society hides its biggest lie of all—the lie of guaranteed, unending economic growth—behind a camouflage of political controversies. Even in relatively calm times, the über-lie was watertight: almost no one questioned it. Like all lies, it served to divert attention from an unwanted truth—the truth of our collective vulnerability to depletion, pollution, and the law of diminishing returns. Now that truth is more hidden than ever.

Our new government shows nothing but contempt for environmentalists and it plans to exit Paris climate agreement. Denial reigns! Chaos threatens! So why bother bringing up the obscured reality of limits to growth now, when immediate crises demand instant action? It’s objectively too late to restrain population and consumption growth so as to avert what ecologists of the 1970s called a “hard landing.” Now we’ve fully embarked on the age of consequences, and there are fires to put out. Yes, the times have moved on, but the truth is still the truth, and I would argue that it’s only by understanding the biophysical wellsprings of change that can we successfully adapt, and recognize whatever opportunities come our way as the pace of contraction accelerates to the point that decline can no longer successfully be hidden by the elite’s strategies.

Perhaps Donald Trump succeeded because his promises spoke to what civilizations in decline tend to want to hear. It could be argued that the pluralistic, secular, cosmopolitan, tolerant, constitutional democratic nation state is a political arrangement appropriate for a growing economy buoyed by pervasive optimism. (On a scale much smaller than contemporary America, ancient Greece and Rome during their early expansionary periods provided examples of this kind of political-social arrangement). As societies contract, people turn fearful, angry, and pessimistic—and fear, anger, and pessimism fairly dripped from Trump’s inaugural address. In periods of decline, strongmen tend to arise promising to restore past glories and to defeat domestic and foreign enemies. Repressive kleptocracies are the rule rather than the exception.

If that’s what we see developing around us and we want something different, we will have to propose economic, political, and social forms that are appropriate to the biophysical realities increasingly confronting us—and that embody or promote cultural values that we wish to promote or preserve. Look for good historic examples. Imagine new strategies. What program will speak to people’s actual needs and concerns at this moment in history? Promising a return to an economy and way of life that characterized a past moment is pointless, and it may propel demagogues to power. But there is always a range of possible responses to the reality of the present. What’s needed is a new hard-nosed sort of optimism (based on an honest acknowledgment of previously denied truths) as an alternative to the lies of divisive bullies who take advantage of the elites’ failures in order to promote their own patently greedy interests. What that actually means in concrete terms I hope to propose in more detail in future essays.

The Extreme Implausibility of Ecomodernism.

Another essay by Ted Trainer.

Abstract: “Ecomodernism” is a recently coined term for that central element in mainstream Enlightenment culture previously well-described as “Tech-fix faith”. The largely taken for granted assumption has been that by accelerating modern technologies high living standards can be achieved for all, while resolving resource and ecological problems.  The following argument is that ecomodernism falls far short of having a substantial, persuasive or convincing case in its support. It stands as a contradiction of the now voluminous “limits to growth” literature, but it does not attempt to offer a case against the limits thesis. Elements in the limits case will be referred to below but the main line of argument will be to do with the reasons why achievement of the reductions and “decouplings” assumed by ecomodernism is extremely implausible. The conservative social and political implications are noted before briefly arguing that the solution to global problems must be sought via The Simpler Way.

What is ecomodernism?.

The 32 page Ecomodernist Manifesto (2015), by 18 authors, is a clear and emphatic restatement of the common belief that technical advance within the existing social structure can or will solve global problems, and there is therefore no need for radical change in directions, systems, values or lifestyles. Thus the fundamental commitment to ever more affluent “living standards”, capital intensive systems, technical sophistication and constantly rising levels of consumption and GDP is sound, and indeed necessary as it is the only way to enable the future technical advance that it is believed will solve global problems. This will enable human demands to be met while resource and ecological impacts on nature are reduced, thus making it possible to set more of nature aside to thrive. Modern agriculture for instance will producer more from less land, enabling more to be returned to nature and freeing Third World people from backbreaking work while moving into urban living.  Thus the fundamental assumption frequently asserted is that economic growth can be “decoupled” from the environment.

These kinds of visions would obviously require vastly increased quantities of energy but renewable sources are judged not to be capable of providing these, so it is no surprise to find late in the document that it is being assumed that nuclear reactors are going to do the job, nor that the pro-nuclear Breakthrough Institute champions the Manifesto.

Unfortunately the Manifesto is little more than a claim.  It provides almost no supporting case apart from giving some examples where technical advance has improved human welfare at reduced resource or ecological impact. It does not deal with the many reasons for thinking that technical advance cannot do what the ecomodernists are assuming it can do.  Above all it does not provide grounds for thinking that that resource demand and ecological damage can be sufficiently decoupled from economic growth. When one of the authors was asked for the supporting case reference was made to the 106 page document Nature Unbounded by Blomqvist, Nordhaus and Shellenberger, (2015.) However this document too is essentially a statement of claims and faith and can hardly be said to present a case that those claims can be realized.

The following discussion is mainly intended to show how implausible and unsubstantiated the general “tech-fix” and decoupling claims are, and that they are contrary to existing evidence.  Most if not all critical discussions of ecomodernism and of left modernization theorists such as Phillips (2015), e.g., by Hopkins (2015), Caradonna et al., 2015, Crist, (2015) and Smaje, (2015a, 2015b), have been impressionistic and “philosophical”. In contrast, the following analysis focuses on numerical considerations which establish the enormity of the ecomodernist claims. When estimates and actual numbers to do with resource demands, resource bases, and ecological impacts are attended to it becomes clear that the task for technical advance set by the ecomodernists is implausible in the extreme.

The basic limits to growth thesis.

The “limits to growth” thesis is that with respect to many factors crucial to planetary sustainability affluent-industrial-consumer society is grossly unsustainable. It has already greatly exceeded important limits. Levels of production and consumption are far beyond those that could be kept up for long or extended to all people.  Present consumption levels are achieved because resource and ecological “stocks” are being depleted much faster than they can regenerate.

But the unsustainable present levels of production, consumption, resource use and environmental impact only begin to define of the problem.  What is overwhelmingly crucial is the universal obsession with continual, never ending economic growth, i.e., with increasing production and consumption, incomes and GDP as much as possible and without limit.  The most important criticism of the ecomodernist position is its failure to grasp the magnitude of the task it confronts when the present overshoot is combined with the commitment to growth.  The main concern in the following discussion is with quantities and multiples, to show how huge and implausible ecomodernist achievements and decouplings would have to be.

The magnitude of the task.

It is the extent of the overshoot that is crucial and not generally appreciated. This is the issue which the ecomodernists fail to deal with and it only takes a glance at the numbers to see how implausible their pronouncements are in relation to the task they set themselves. Their main literature makes no attempt to carry out quantitative examinations of crucial resources and ecological issues with a view to showing that the apparent limits can be overcome.

Let us look at the overall picture revealed when some simple numerical aggregates and estimates are combined.  The normal expectation is for around 3% p.a. growth in GDP, meaning that by 2050 the total amount of producing and consuming going on in the world would be about three times as great as at present. World population is expected to be around 10 billion by 2050.  At present world  $GDP per capita is around $13,000, and the US figure is around $55,000. Thus if we take the ecomodernist vision to imply that by 2050 all people will be living as Americans will be living then, total world output would have to be around 3 x 10/7 x 55,000/13,000 = 18 times as great as it is now.  If the assumptions are extended to 2100 the multiple would be in the region of 80.

However, even the present global level of producing and consuming has an unsustainable level of impact.  The world Wildlife Fund’s “Footprint” measure (2015) indicates that the general overshoot is around 1.5 times a sustainable rate.  (For some factors, notably greenhouse gas emissions, the multiple is far higher.) This indicates that the target for the ecomodernist has to be to reduce overall resource use and ecological impact per unit of output by a factor of around 27 by 2050, and in the region of 120 by 2100. In other words, by 2050 technical advance will have to have reduced the resource demand and environmental impact per unit of output to under 4% of their present levels.

The consideration of required multiples shows the inadequacy of the earlier pronouncements and expectations of the well-known tech-fix optimist Amory Lovins who enthused about the possibility of “Factor Four” or better reductions in materials and energy uses per unit of GDP.  (Von Weisacker and Lovins, 1997, and Hawken, Lovins and Lovins, 1999).If there is a commitment to constant, limitless increase in economic output then the reductions in resource use and environmental damage that can be achieved by such technical advance are soon likely to be overwhelmed.  For instance if use and impact rates per unit of GDP were cut by one-third, but 3% p.a. growth in total output continued, then in about 17 years the resource demands and impacts would be back up to as high as they were before the cuts, and would be twice as great in another 23 years.

This issue of multiples is at the core of the limits and decoupling issues. If ecomodernists wish to be taken seriously they must provide a numerical case showing that in all the relevant domains the degree of decoupling that can be achieved is likely to be of the magnitude that would be required.  There appears to be no ecomodernist text which even attempts to do this.  At best their case refers to a few instances where impressive decoupling has taken place.

Note also the importance here of the Leibig “law of the minimum.” It does not matter how spectacular various technical gains can be if there remains one crucial area where they can’t be made on the required scale.  Plants for instance might have available all the nutrients they need except for one required in minute quantities but if it is not available there will be little or no growth.  High-tech systems often depend heavily on tiny quantities of “mineral vitamins”, notably rare earths which are extremely scarce.

The typically faulty national accounting.

An easily overlooked factor is that in general measures and indices of rich world resource and ecological performance greatly misrepresent and underestimate the seriousness of the situation, because they do not include the large volumes of energy, materials and ecological impact embodied in imported goods.  Rich countries now do not carry out much manufacturing but import most of the goods they consume from Third World plantations and factories.  The implications for resource depletion and ecological impact have only recently begun to be studied. (Weidmann, et al., 2014, 2015, Lenzen, et al., 2012, Wiebe, et al,

2012, Dittrich, et al., 2014, Schütz, et al., 2004.)

An example is given by the conventional measure of CO2 emissions. Australia’s 550 MtCO2e/y equates to a per capita rate of around 25 t/y, which is about the highest in the world. But this does not include the emissions in Third World countries generated by the production of goods imported into Australia.  For Australia and for the UK this amount is actually about as great as the emissions within the country.  (Clark, 2011, Australian Government Climate Change Authority, 2013.)

In addition Australia’s “prosperity” is largely achieved by exporting coal, oil and gas and these contain about three times as much carbon as all the energy used within Australia.  It could be argued therefore that the country’s contribution to the greenhouse gas problem more or less corresponds to five times the official and usually quoted 25 t/pp/y.  The IPCC estimates that by 2050 global emissions must be cut to about 0.3 t/pp/y. (IPCC, 2014.)  This is around one-three hundredth of the amount Australia is now responsible for. Again the centrality of the above magnitude point is evident; how aware are tech-fix optimists of the need for reductions of such proportions?

Assessing the validity of the general “tech-fix” thesis.

Firstly attention will be given to some overall numerical considerations which show the extreme implausibility of the general tech-fix claim, such as the gulf between current “decoupling” achievements and the far higher levels that ecomodernism would require. But that does not take into account the fact that it is going to take increasing effort just to maintain current achievements, for instance as ore grades deteriorate. This what the limits to growth analysis makes clear.  The added significance of this will be discussed later via brief examination of some domains such as energy scarcity, declining ore grades, and deteriorating ecological conditions.

How impressive have the overall gains been?

It is commonly assumed that in general rapid, large or continuous technical gains are being routinely made in crucial areas such as energy efficiency, and will continue if not accelerate.  As a generalisation this belief is quite challengeable. Ayres (2009) notes that for many decades there have been plateaus for the efficiency of production of electricity and fuels, electric motors, ammonia and iron and steel production. His Fig. 4.21a shows no increase in the overall energy efficiency of the US economy since 1960.  He reports that the efficiency of electrical devices in general has actually changed little in a century (2009) “…the energy efficiency of transportation probably peaked around 1960.” This has been partly due to greater use of accessories since then. Ayres notes that reports tend to publicise selected isolated spectacular technical advances and this is misleading regarding long term average trends across whole industries or economies. Mackay (2008) reports that little gain can be expected for air transport.  Huebner’s historical study (2005) found that the rate at which major technical advances have been made (per capita of world population) is declining.  He says that for the US the peak was actually in 1916.

Decoupling can be regarded as much the same as productivity growth and this has been in long term decline since the 1970s. Even the advent of computerisation has had a surprisingly small effect, a phenomenon now labelled the “Productivity Paradox.”

The historical record suggests that at best productivity gains have been modest. It is important not to focus on national measures such as “Domestic Materials Consumption” as these do not take into account materials in imported goods.  Thus the OECD (2015) claims that materials used within its countries has fallen 45% per dollar of GDP, but this figure does not take into account materials embodied in imported goods. When they are included rich countries typically show very low or worsening ratios. The commonly available global GDP (deflated) and energy use figures between 1980 and 2008 reveals only a 0.4% p.a. rise in GDP per unit of energy consumed.   Hattfield-Dodds et al. (2015) say that the efficiency of materials use has been improving at c. 1.5% p.a., but they give no evidence for this and other sources indicate that the figure is too high. Weidmann et al. (2014) show that when materials embodied in imports are taken into account rich countries have not improved their resource productivity in recent years. They say “…for the past two decades global amounts of iron ore and bauxite extractions have risen faster than global GDP.” “… resource productivity…has fallen in developed nations.” “There has been no improvement whatsoever with respect to improving the economic efficiency of metal ore use.”

The fact that the “energy intensity” of rich world economies, i.e., ratio of GDP to gross energy used within the country has declined is often seen as evidence of decoupling but this is misleading. It does not take into account the above issue of failure to include energy embodied in imports. Possibly more important is the long term process of “fuel switching”, i.e., moving to forms of energy which are of “higher quality” and enable more work per unit. For instance a unit of energy in the form of gas enables more value to be created than a unit in the form of coal, because gas is more easily transported, switched on and off, or converted from one function to another, etc. (Stern and Cleveland, 2004, p. 33, Cleveland et al., 1984, Kaufmann, 2004,  Office of Technology Assessments, 1990, Berndt, 1990, Schurr and Netschurt, 1960.)

Giljum et al. (2014, p. 324) report only a 0.9% p.a. improvement in the dollar value extracted from the use of each unit of minerals between 1980 and 2009, and that over the 10 years before the GFC there was no improvement. “…not even a relative decoupling was achieved on the global level.” They note that the figures would have been worse had the production of much rich world consumption not been outsourced to the Third World. Their Fig. 2, shows that over the period 1980 to 2009 the rate at which the world decoupled materials use from GDP growth was only one third of that which would have achieved an “absolute” decoupling, i.e., growth of GDP without any increase in materials use.

Diederan’s account (2009) of the productivity of minerals discovery effort is even more pessimistic. Between 1980 and 2008 the annual major deposit discovery rate fell from 13 to less than 1, while discovery expenditure went from about $1.5 billion p.a. to $7 billion p.a., meaning the productivity expenditure fell by a factor in the vicinity of around 100, which is an annual decline of around 40% p.a. Recent petroleum figures are similar; in the last decade or so discovery expenditure more or less trebled but the discovery rate has not increased.

A recent paper in Nature by a group of 18 scientists at the high-prestige Australian CSIRO (Hatfield-Dodds et al., 2015) argued that decoupling could eliminate any need to worry about limits to growth at least to 2050. The article contained no support for the assumption that the required rate of decoupling was achievable and when it was sought (through personal communication) reference was made to the paper by Schandl et al. (2015.)  However that paper contained the following surprising statements, “ … there is a very high coupling of energy use to economic growth, meaning that an increase in GDP drives a proportional increase in energy use.”  (They say the EIA, 2012, agrees.) “Our results show that while relative decoupling can be achieved in some scenarios, none would lead to an absolute reduction in energy or materials footprint.” In all three of their scenarios “…energy use continues to be strongly coupled with economic activity…”

The Australian Bureau of Agricultural Economics (ABARE, 2008) reports that the energy efficiency of energy-intensive industries is likely to improve by only 0.5% p.a. in future, and of non-energy-intensive industries by 0.2% p.a. In other words it would take 140 years for the energy efficiency of the intensive industries to double the amount of value they derive from a unit of energy.

Alexander (2014) concludes his review of decoupling by saying, ”… decades of extraordinary technological development have resulted in increased, not reduced, environmental impacts.”  Smil (2014) concludes that even in the richest countries absolute dematerialization is not taking place. Alvarez found that for Europe, Spain and the US GDP increased 74% in 20 years, but materials use actually increased 85%. (Latouche, 2014.) Similar conclusions re stagnant or declining materials use productivity etc. are arrived at by Aadrianse, 1997, Dettrich et al., (2014), Schutz, Bringezu and Moll, (2004), Warr, (2004), Berndt, (undated), and Victor (2008, pp. 55-56).

These sources and figures indicate the lack of support for the ecomodernists’ optimism. It was seen above that they are assuming that in 35 years time there can be massive absolute decoupling, i.e., that energy, materials and ecological demand associated with $1 of GDP can be reduced by a factor of around 27. But even if the 1.5% p.a. rate Hattfield-Dodds et al. say has been the recent achievement for materials use could be maintained the reduction would only be around a factor of 1.7, and various sources noted above say that their assumed rate is incorrect. There appears to be no ecomodernist literature that even attempts to provide good reason to think a general absolute decoupling is possible, let alone on the required scale.

The overlooked role of energy in productivity growth and decoupling.

Discussions of technical advance and economic growth have generally failed to focus on the significance of increased energy use. Previously productivity has been analysed only in terms of labour and capital “factors of production”, but it is now being recognized that in general greater output etc. has been achieved primarily through increased use of energy (and switching to fuels of higher “quality”, such as from coal and gas to electricity.)  Agriculture is a realm where technical advance has been predominantly a matter of increased energy use. Over the last half century productivity measured in terms of yields per ha or per worker have risen dramatically, but these have been mostly due to even greater increases in the amount of energy being poured into agriculture, on the farm, in the production of machinery, in the transport, pesticide, fertilizer, irrigation, packaging and marketing sectors, and in getting the food from the supermarket to the front door, and then dealing with the waste food and packaging. Less than 2% of the US workforce is now on farms, but agriculture accounts for around 17% of all energy used (not including several of the factors listed above.) Similarly the “Green Revolution” has depended largely on ways that involve greater energy use.

Ayres, et al., (2013), Ayres, Ayres and Warr (2002) and Ayres and Vouroudis (2013) are among those beginning to stress the significance of energy in productivity, and pointing to the likelihood of increased energy problems in future and thus declining productivity. Murillo-Zamorano, (2005, p. 72) says  “…our results show a clear relationship between energy consumption and productivity growth.” Berndt (1990) finds that technical advance accounts for only half the efficiency gains in US electricity generation. These findings caution against undue optimism regarding what pure technical advance can achieve independently from increased energy inputs; in general its significance for productivity gains appears not to have been as great as has been commonly assumed.

The productivity trend associated with this centrally important factor, energy, is itself in serious decline, evident in long term data on EROI ratios. Several decades ago the expenditure of the energy in one barrel of oil could produce 30 barrels of oil, but now the ratio is around 18 and falling. The ratio of petroleum energy discovered to energy required has fallen from 1000/1 in 1919 to 5/1 in 2006. (Murphy, 2010.) Murphy and others suspect  that an industrialised society cannot be maintained on a general energy ratio under about 10. (Hall, Lambert and Balough, 2014.)

The changing components of GDP.

Over recent decades there has been a marked increase in the proportion of rich nation GDP that is made up of “financial” services. These stand for “production” that takes the form of key strokes moving electrons around.  A great deal of it is wild speculation, making risky loans and making computer driven micro-second switches “investments”. These operations deliver massive increases in income to banks and managers, and these have significantly contributed to GDP figures. It could be argued that this domain should not be included in estimates of productivity because it misleadingly inflates the numerator in the output/labour ratio.

When output per worker in the production of “real” goods and services such as food and vehicles, or aged care is considered very different impressions can be gained.  For instance Kowalski (2011) reports that between 1960 and 2010 world cereal production increased 250%, but nitrogen fertilizer use in cereal production increased 750%, and land area used increased 40%. This aligns with the above evidence on steeply falling productivity of various inputs for ores and energy. It is therefore desirable to avoid analysing productivity, the “energy intensity” of an economy, and decoupling achievements in relation to the GDP measure.

Factors limiting the benefits from a technical advance.

There are several factors which typically determine the gains a technical advance actually enables are well below those that seem possible at first.  Engineers and economists make the following distinctions.

“Technical potential”  refers to what could be achieved if the technology could be fully applied with no regard to cost or other problems.

Economic (or ecological) potential”.  This is usually much less than the technical potential because to achieve all the gains that are technically possible would cost too much.  For instance some The Worldwide Fund for Nature quotes Smeets and Faiij (2007) as finding that it would be technically possible for the world’s forests to produce another 64 EJ/y of biomass energy p.a., but they say that the ecologically tolerable potential is only 8 EJ/y.

What are the net gains?  Enthusiastic claims about a technical advance typically focus on the gains and not the costs which should be subtracted to give a net value.  For instance the energy needed to keep buildings warm can be reduced markedly, but it costs a considerable amount of energy to do this, in the electricity needed to run the air-conditioning and heat pumps, and in the energy embodied in the insulation and triple glazing. There are also knock-on effects.  The Green Revolution doubled food yields, but only by introducing crops that required high energy inputs in the form of expensive fertlilzer, seeds and irrigation, and created social costs to do with the disruption of peasant communities.

  • What is socially/politically possible?  There are limits set by what people will accept.  It would be technically possible for many more people in any city to get to work by public transport, but large numbers would not give up the convenience of their cars even if they saved money doing so.
  • The Jeavons or “rebound” effect.  There is a strong tendency for savings made possible by a technical advance to be spent on consuming more of the thing saved, or something else.

Thus it is important to recognise that initial claims usually refer to “technical potential”, but significantly lower savings etc. are likely in the real world.

Now add the worsening limits.

The discussion so far has only dealt with decoupling achievements to date, but the difficulties involved in those achievements are in general likely to have been much less severe than those ahead, as there is continued deterioration in ore grades, forests, soils, chemical pollution, water supplies etc.  It is important now to consider briefly some of these domains, to see how they will make the task for the ecomodernist increasingly difficult.

Before looking at some specific areas the general “low hanging fruit” effect should be mentioned.  When effort is put into dealing with problems, recycling, conserving, increasing efficiency etc. the early achievements might be spectacular but as the easiest options are used up progress typically becomes more difficult and slow. This is so even when there are no problems of dwindling resource availability.

                        Minerals.

The grades of several ores being mined are falling and production costs have increased considerably since 1985. Topp (2008) reports that the productivity for Australian mining has declined 24% between 2000 and 2007. While reserve estimates can be misleading as they only state quantities miners have found to date, and they often increase over time, there is considerable concern about the depletion rate.

Dierderen (2009) says that continuation of current consumption rates will mean that we will have much less than 50 years left of cheap and abundant access to metal minerals, and that it will take exponentially more energy and minerals input to grow or even sustain the current extraction rate of metal minerals. He expects copper, nickel, molybdenum and cobalt to peak before 2035. Deideren’s conclusion is indeed, as his title says, sobering; “The peak in primary production of most metals may be reached no later than halfway through the 2020s.” (p. 23.) “Without timely implementation of mitigation strategies, the world will soon run out of all kinds of affordable mass products and services.”  Such as… “cheap mass-produced consumer electronics like mobile phones, flat screen TVs and personal computers, for lack of various scarce metals (amongst others indium and tantalum). Also, large-scale conversion towards more sustainable forms of energy production, energy conversion and energy storage would be slowed down by a lack of sufficient platinum-group metals, rare-earth metals and scarce metals like gallium. This includes large-scale application of high-efficiency solar cells and fuel cells and large-scale electrification of land-based transport.” Deideren points out that Gallium, Germanium, Indium and Tellurium are crucial for renewable technologies but are by-products currently available in low quantity from the mining of other minerals.  If the latter peak so will the availability of the former.

Scarcities in one domain often have knock-on and negative feedback effects in others.  Diederan says, “The most striking (and perhaps ironic) consequence of a shortage of metal elements is its disastrous effect on global mining and primary production of fossil fuels and minerals: these activities require huge amounts of main and ancillary equipment and consumables (e.g. barium for barite based drilling mud)”. (p. 9.)

The ecomodernist’s response must be to advocate mining poorer grade ores, but this means dealing with marked increases in energy and environmental costs.

  • The quantity of rock that has to be dug up increases. For ores at half the initial grade the quantity doubles, and so does the energy needed to dig, transport and crush it.
  • Poorer ores require finer grinding and more chemical reagents to release mineral components, meaning greater energy demand and waste treatment.
  • Meanwhile the easiest deposits to access are being depleted so it takes more energy to find, get to, and work the newer ones. They tend to be further away, deeper, and smaller.
  • Processing rich ores can be chemically quite different to processing poor ores. Only a very small proportion of any mineral existing in the earth’s crust has been concentrated by natural processes into ore deposits, between .001% and .01%, and the rest exists in common rock, mostly in silicates which are more energy-intensive to process than oxides and sulphides.  To extract a metal from its richest occurrence in common rock would take 10 to 100 times as much energy as to extract if from the poorest ore deposit. To extract a unit of copper from the richest common rocks would require about 1000 times as much energy per kg as is required to process ores used today.

Now consider the minerals situation in relation to the multiples issue. At present only a few countries are using most of the planet’s minerals production.  For instance the per capita consumption of iron ore for the ten top consuming countries is actually around 90 times the figure for all other countries combined. (Weidmann et al., 2013.) How long would mineral supply hold up, at what cost, if 9 – 10 people billion were to try to rise to rich world “living standards”? How likely is it that in view of current ore grade depletion rates and the miniscule decoupling achievement for minerals, the global amount of producing and consuming could multiply by 27, or 120, while the absolute amount of minerals consumed declined markedly?

The ecomodernist cannot hope to deal with the minerals problem without assuming very large scale adoption of nuclear energy, which they are willing to do.

Climate.

Most climate scientists now seem to accept the approach put forward by Meinshausen et al., (2009), and followed by the IPCC (2013) in analyzing in terms of a budget, an amount of carbon release that must not be exceeded if the 2 degree target is to be met.  They estimate that to have a 67% chance of keeping global temperature rise below this the amount of CO2e that can be released between 2000 and 2050 is 1,700 billion tonnes. By 2012 emissions accounted for 36% of this amount, meaning that if the present emission rate is kept up the budget would have been used up by 2033.  Given the seriousness of the possible consequences many regard a 67% chance as being too low and a2 degree rise as too high. (Anderson and Bows, 2008, and Hansen, 2008.)  For an 80% chance the budget limit would be 1,370 billion tonnes.

Few would say there is any possibility of eliminating emissions by 2033. Many emissions come from sources that would be difficult to control or reduce, such as carbon electrodes in the electric production of steel and aluminium. Only about 40% of US emissions come from power generation. Thus power station Carbon Capture and Storage technology cannot solve the problem.

Even the IPCC’s most optimistic emissions reduction scenario, RCP 2.6, could be achieved only if as yet non-existent technology will be able to take 1 billion tonnes of carbon out of the atmosphere every year through the last few decades of this century. (IPCC, 2014.)

Ecomodernists mostly regard the climate problem as solvable by the intensive adoption of nuclear energy. However even the most rapid build conceivable could not achieve the Meinschausen et al. target.

Urbanisation.

About half the world’s people now live in cities, and the ecomodernist strongly advocates increasing this markedly, on the grounds that intensification of settlement will enable freeing more space for nature.  This is an area where knock-on effects are significant. Urban living involves many high resource and ecological costs, including having to move in vast amounts of energy, goods, services and workers, to maintain elaborate infrastructures including those to lift water and people living in high-rise apartments, having to move out all “wastes”, having to provide artificial light, heating, cooling, air purification, having to build freeways, bridges, railways, airports, container terminals, and having to staff complex systems with expensive highly trained professionals and specialists.  Little or none of this dollar, energy, resource or ecological cost has to be met when people live in villages (See on Simpler Way settlements below).

The frequent superficiality and invalidity of the Manifesto’s case is illustrated by the following statement. “Cities occupy just 1 to 3 percent of the Earth’s surface, yet are home to nearly 4 billion people. As such, cities both drive and symbolize the decoupling of humanity from nature, performing far better than rural economies in providing efficiently for material needs…” This statement overlooks the vast areas needed to produce and transport food etc. into the relatively small urban areas. If four billion were to live as San Franciscans do now, with a footprint over 7 ha per person, the total global footprint would be almost 30 billion ha, 200% of the Earth’s surface, not 1- 3%. (WWF, 2014.) Urbanisation does not  “decouple humanity from nature”.

Biological resources and impacts.

Perhaps the most worrying limits being encountered are not to do with minerals or energy but involve the deterioration of biological resources and environmental systems. The life support systems of the planet, the natural resources and processes on which all life on earth depends, are being so seriously damaged that the World Wildlife Fund claims there has been a 30% deterioration since about 1970. Steffen et al., (2015) state much the same situation. A brief reference to a number of impacts is appropriate here to again indicate the magnitude of present problems and their rate of growth.

Biodiversity loss.

Species are being driven to extinction at such an increasing rate that it is claimed the sixth holocaust of biodiversity loss has begun. The rate has been estimated at 114 times the natural background rate. (Ceballos, et al., 2015, Kolbert, 2014.) The numbers or mass of big animals has declined dramatically. “… vertebrate species populations across the globe are, on average, about half the size they were 40 years ago.” (Carrington, 2014.) The mass of big animals in the sea is only 10% of what it was some decades ago. The biomass of corals on the Great Barrier Reef is only half what it was about three decade ago. By the end of the 20th century half the wetlands and one third of coral reefs had been lost. (Washington, 2014.)

Disruption of the nitrogen cycle.

Humans are releasing about as much nitrogen via artificial production, especially for agriculture, as nature releases. This has been identified as one of the nine most serious threats to the biosphere by the Planetary Boundaries Project. (Rockstrom and Raeworth, 2014.)

The increasing toxicity of the environment.

Large volumes of artificially produced chemicals are entering ecosystems disrupting and poisoning them.  This includes the plastics concentrating in the oceans and killing marine life.

Water.

Serious water shortages are impacting in about 80 countries. More than half the world’s people live in countries where water tables are falling. Over 175 million Indians and 130 million Chinese are fed by crops watered by pumps running at unsustainable rates. (Brown, 2011, p. 58.) Access to water will probably be the major source of conflict in the world in coming years. About 480 million people are fed by food produced from water pumped from underground. The water tables are falling fast and the petrol to run the pumps might not be available soon. In Australia overuse of water has led to serious problems, such as salinity in the Murray-Darling system. By 2050 the volume of water in these rivers might be cut to half the present amount, as the greenhouse problem impacts.

Fish.

Nearly all fisheries are being over-fished and the global fish catch is likely to go down from here on.  The mass of big fish in the oceans, such as shark and tuna, is now only 10% of what it was some decades ago. Ecomodernists assume that aquaculture will solve the fish supply problem. It is not clear what they think the farmed fish will be fed on.

Oceans.

Among the most worrying effects is the increasing acidification of the seas, dissolving the shells of many ocean animals, including the krill which are at the base of major ocean food chains.  This effect plus the heating of the oceans is seriously damaging corals.  The coral life on the Great Barrier Reef is down 30% on its original level, and there is a good chance the whole reef will be lost in forty years. (Hoegh-Guldberg, 2015.)

Food, land, agriculture.

Food supply will have to double to provide for the expected 2050 world population, and it is increasingly unlikely that this can be done. Food production increase trends are only around 60% of the rate of increase needed. (Ray, et al., 2013.) Food prices and shortages are already serious problems, causing riots in some countries.  If all people we will soon have on earth had an American diet we would need 5 billion ha of cropland, but there are only 1.4 billion ha on the planet and that area is likely to reduce as ecosystems deteriorate, water supply declines, salinity and erosion continue, population numbers and pressures to produce increase, land is used for new settlements and to produce more meat and bio-fuels, and as global warming has a number of negative effects on food production.

Burn, (2015) and Vidal (2010) both report the rate of food producing land loss at 30 million ha p.a. Vidal says, “…the implications are terrifying”, and he believes major food shortages are threatening. Pimentel says one third of all cropland has been lost in the last 40 years. China might be the worse case, losing 600 square miles p.a. in the 1950 – 1970 period, but by 2000 the rate had risen to 1,400 square miles p.a.  For 50 years about 500 villages have had to be abandoned every year due to incoming sand from the expanding deserts. If the estimates by Burn and Vidal are correct then more than 1 billion ha of cropland will have been lost by 2050, which is two-thirds of all cropland in use today.

The Ecomodernist Manifesto devotes considerable attention to the issue of future food production, using it as an example of the wonders technical advance can bring, including liberating peasants from backbreaking work. It is claimed that advances in modern agriculture will enable production of far more food on far less land, enabling much land to go back to nature. There is no recognition of the fact that modern agriculture is grossly unsustainable, on many dimensions.  It is extremely energy intensive, involving large scale machinery, international transport, energy-intensive inputs of fertilizer and pesticides, packaging, warehousing, freezing, dumping of less than perfect fruit and vegetables, serious soil damage through acidification and compaction, carbon loss and erosion, the energy-costly throwing away of nutrients in animal manures, the destruction of small scale farming and rural communities, the loss of the precious heritage that is genetic diversity … and the loss of food nutrient and taste quality (most evident in the plastic tomato.)

On all these dimensions peasant and home gardening and other elements in local agriculture such as ”edible landscapes”, community gardens and commons are superior. The one area where modern agriculture scores better is to do with labour costs, but that is due to the use of all that energy-intensive machinery. Ecomodernists do not seem to realize what a fundamental challenge is set for them by the well-established “inverse productivity relationship”, i.e., the fact that small scale food producers achieve higher yields per ha. (Smaje, 2015a, 2015b.) They are able to almost completely avoid food packaging, advertising and transport costs, to recycle all nutrients to local soils, benefit from overlaps and multiple functions (e.g., geese weed orchards, ducks eat snails, kitchen scraps feed poultry…) Possibly most importantly, local food production systems maximize the provision of livelihoods and are fundamental elements in resilient and sustainable communities.

Again a daunting challenge is set for the ecomodernist. Presumably the far higher yields from far less land will involve energy intensive high-rise greenhouses, water desalinisation, aquaculture, near 100% phosphorus and other nutrient recycling, elimination of nitrogen run-off, restoration of soil carbon levels, synthetic meat, and extensive global transport and packaging systems. Again numerical analyses aimed at showing what the energy, materials  and dollar budgets would be, or that the goals can be met, are not offered. In addition a glance at the tech fix vision for future food supply reveals the many knock on effects that would multiply problems in many other areas, most obviously energy, infrastructure and water provision and the associated demand for materials.

A glance at the energy implications for beef production should again establish the magnitude point. To produce one kg of beef take can take 20,000 litres of water, and it can take 4 kWh to desalinize 1 liter of water. Again it is evident that there would have to be very large scale commitment to nuclear energy.

            Summarising the biological resource situation.

The environmental problem is essentially due to the huge and unsustainable volumes of producing and consuming taking place.  Vast quantities of resources are being extracted from nature and vast quantities of wastes are being dumped back into nature. Present flows are grossly unsustainable but the ecomodernist believes the basic commitment to ever-increasing “living standards” that is creating the problems can and should continue, while population multiplies by 1.5, resources dwindle, and consumption multiplies perhaps by eight by 2100.

The energy implications.

In all the fields discussed it is evident that the ecomodernist vision would have to involve a very large increase in energy production and consumption, including for processing lower grade ores, producing much more food from much less land, desalinisation of water, dealing with greatly increased amounts of industrial waste (especially mining waste), and constructing urban infrastructures. The “no-limits-to-growth” scenario for Australia 2050 put forward by Hattfield-Dodds et al. concludes that present energy use would have to multiply by 2.7, more than most if not all other projections, and their scenarios do not take into account the energy needed to deal with any of the knock-on effects discussed above. (And their conclusion is based on a highly implausible rate of decoupling materials use from GDP growth, i.e., up to 4.5% p.a.)

If 9 billion people were to live on the per capita amount of energy Americans now average, world energy consumption in 2050 would be around x5 (for the US to world average ratio) x10/7 (for population growth) times the present 550 EJ p.a., i.e., around 3,930 EJ. Let us assume it is all to come from nuclear reactors, that technical advance cuts one-third off the energy needed to do everything, but that moving to poorer ores, desalinisation etc. and converting to (inefficient) hydrogen supply for many storage and transport functions counterbalance that gain.  The nuclear generating capacity needed would be around 450 times as great as at present.

Conclusions re the significance of the limits to growth.

This brief reference to themes within the general “limits to growth” account makes it clear that the baseline on which ecomodernist visions must build is not given by presentconditions. As Steffen et al. (2015) stress the baseline is one of not just deteriorating conditions, but accelerating deterioration. It is as if the ecomodernists are claiming that their A380 can be got to climb at a 60 degree angle, which is far steeper than it has ever done before, but at present it is in an alarming and accelerating decline with just about all its systems in trouble and some apparently beyond repair. The problem is the wild party on board, passengers and crew dancing around a bonfire and throwing bottles at the instruments, getting more drunk by the minute. A few passengers are saying the party should stop, but no one is listening, not even the pilots. The ecomodernist’s problem is not just about producing far more metals, it is about producing far more as grades decline, it is not just about producing much more food, it is about producing much more despite the fact that problems to do with water availability, soils, the nitrogen cycle, acidification, and carbon loss are getting worse.  It can be argued that on many separate fronts halting the deteriorating trends is now unlikely to be achieved. Yet the ecomodernist wants us to believe that the curves can be made to cease falling and to rise dramatically, without abandoning the quests for affluence and growth which are responsible for their deterioration.  Stopping the party is not thought to warrant consideration.

            The implications for centralisation, control and power.

The ecomodernist vision would have to involve vast, technically sophisticated, expert-run, bureaucratized and centralized global systems, most obviously for the control of the nuclear sector, e.g., to prevent access to weapons grade material. Both corporate and governmental agencies would have to be very large in scale, and relations between the corporate sector and top levels of government would set problems to do with openness, public accountability, democratic control, and corruption. Most production would be from a relatively few gigantic and automated mines, factories, feed lots, mega-greenhouses and plantations compressed into the relatively few best sites.  How this would provide jobs and livelihoods to perhaps 6 billion Third world poor would need to be explained. The provision of large amounts of capital would probably become much more centralised and problematic than it has been in the GFC era.

A “development” model focused on these massive, centralized, expert-dependent and capital intensive systems is not obviously going to improve the already severe problem of global inequality. Mega corporations will run the automated vertical farms and desal plants, assisted by governments who in the past have had no difficulty legislating to clear the locals out of the way, as when Third World governments enable GDP-raising palm oil plantations, logging, big dams and aquaculture. Thus Smaje regards ecomodernism as a new enclosure movement.

Morgan (2012) and Korrowicz (2012) provide disturbing accounts of the fragility and lack of resilience of highly integrated and complex systems. Tainter, (1988), draws attention to the way increasing system complexity leads towards negative synergisms and breakdown. For instance where two roads cross in a village no infrastructure might be needed but in a city multi-million dollar flyovers can be required. As Rome’s road system grew the effort needed just to maintain them grew towards taking up all road building capacity. Among the chief virtues of the small and local path are its robustness, redundancy and resilience, the capacity for simple repairs to simple systems, as well as its capacity to provide livelihoods to large numbers of people.

Above all the ecomodernist vision stands for the rejection of any suggestion that the economy needs altering, let alone scrapping, or that rampant-consumer culture needs to be replaced.  The problems are defined as purely technical. If minerals are becoming scare the solution is not to reduce use of them but to increase production of them. Thus there is no need to think about giving up consumerism, economic growth, the market system or the capitalist system. Radical thought and action need not be considered. Smaje describes it as “neoliberalism with a green veneer.” These messages are as consoling to the present working class and the precariat as they are to the capitalist class.

The mistaken “uni-dimensional” assumption.

Frequently evident in ecomodernist thinking is the way that development, emancipation, technology, progress, comfort, the elimination of disease and hunger are seen to lie along the one path that runs from primitive through peasant worlds to the present and the future.  At the modern end of the dimension there is material abundance, science and high technology, the market economy, freedom from backbreaking work, complex civilization with high educational standards and sophisticated culture. It is taken for granted that your choice is only about where you are on that dimension. Third World “development” can only be about moving up the dimension to greater capital investment, involvement in the global market, trade, GDP and consumer society. Thus they see localism and small is beautiful as “going back”, and condemning billions to continued hardship and deprivation.  Opposition to their advocacy of more modernism is met with, “…well, what period in history do you want to go back to?”

This world-view fails to grasp several things.  The first is the possibility that there might be more than one path; the Zapatista’s do not want to follow our path.  Another is that we  might opt for other end points than the one modernization is taking us to.  A third is that we might deliberately select desirable development goals rather than just accept where modernization takes us, and on some dimensions we might choose not to develop any further.  Ecomodernism has no concept of sufficiency or good enough; Smaje sees how it endorses being incessantly driven to strive for bigger and better, and he notes the spiritual costs. Many ecovillages are developed enough.

Possibly most important, it is conceivable that we could opt for a combination of elements from different points on the path. For instance there is no reason why we cannot have both sophisticated modern medicine and the kind of supportive community that humans have enjoyed for millennia, and have both technically astounding aircraft along with small, cheap, humble, fireproof, home made and beautiful mud brick houses, and have modern genetics along with neighbourhood poultry co-ops. Long ago humans had worked out how to make excellent and quite good enough houses, strawberries, dinners and friendships. We could opt for stable, relaxed, convivial and sufficient ways in some domains while exploring better ways in others, but ecomodernists see only two options; going forward or backward. They seem to have no interest in which elements in modernism are worthwhile and which of them should be dumped. The Frankfurt School saw some of them leading to Auschwitz and Hiroshima.

The inability to think in other than uni-dimensional terms is most tragic with respect to Third World “development”.  Conventional-capitalist development theory can only promise a “growth and trickle down” path, which if it continues would take many decades to lift all to tolerable conditions while the rich rise to the stratosphere, but which cannot continue if the limits to growth analysis of the global situation is correct. Yet The Simpler Way might quickly lift all to satisfactory conditions using mostly traditional technologies and negligible capital. (Trainer, 2012, 2013a, 2013b, Leahy, 2009.)

In his critique of Phillips (2014) Smaje (2015b) sees the Faustian bargain here, the readiness to suffer, indeed embrace, the relentless discontent, struggle, disruption and insecurity that modernism involves, without realizing that we might opt to take the benefits of modernism while dumping the disadvantages and designing ways of life that provide security, stability, a relaxed pace and a high quality of life for all.

A radically alternative vision; The Simpler Way.

Until the last decade or so there was no alternative to the dominant implicit ecomodernist world view, but now significant challenges have emerged, most evidently in the overlapping Eco-village, Degrowth, Transition Towns and localism movements. The fundamental beginning point for these is acceptance of the “limits to growth” case that levels of production, consumption, resource use and ecological impact are extremely unsustainable and that the resulting global problems cannot be solved unless there are dramatic reductions.  The core Simpler Way vision claim is that these reductions can be made while significantly improving the quality of life, even in the richest countries, but not without radical change in systems and lifestyles.  Following is a brief indication of some of the main elements in this vision. (For the detailed account see Trainer, 2011.)

The basic settlement form is the small scale town or suburb, restructured to be a highly self-sufficient local economy running mostly on local resources and requiring a minimal amount of resources and goods to be imported from further afield.  State and national governments would still exist but with relatively few functions. There would be extensive development of local commons such as community watersheds, forests, edible landscapes, workshops and windmills etc. and cooperatives would provide many goods and services. Extensive use could be made of high tech systems but mostly relatively low technologies would be used in small firms and farms, especially earth building, hand tool craft production, Permaculture, community gardening and commons. Leisure committees would maintain leisure rich communities, and other committees would manage orchards, woodlots, agricultural research, and the welfare of disabled, teenage, aged and other groups. Local economies would dramatically reduce the need for vehicles and transport, enabling conversion of many roads to community food production.

These settlements would have to be self-governing via thoroughly participatory procedures, including town meetings and referenda. Citizens are the only ones who can understand local conditions, problems and needs, and they would have to work out the best policies for the town and to own the decisions arrived at. Centralised states could not govern them at all effectively, especially given the much diminished resources that will be available to states.  More importantly the town would not meet its own needs well unless its citizens had a strong sense of empowerment and control and responsibility for their own affairs.

Systems, procedures and the overriding ethos would have to be predominantly cooperative and collective, given the recognition that individual welfare would depend heavily on how well the town was functioning. It would not be likely to thrive unless there was an atmosphere of inclusion and care, solidarity and responsibility.

An entirely new kind of economy would be needed, one that did not grow, rationally geared productive capacity to social need, had per capita levels of production, consumption, resource use and GDP far below current levels, was under public control, and was not driven by market forces, profit or competition. However, there might also be a large sector made up of privately owned small firms and farms, producing to sell in local markets, but operating under careful guidelines set by the town to ensure optimum benefit for the town. The transition period would essentially be about slowly establishing those enterprises, infrastructures, cooperatives, commons and institutions (Economy B) whereby the town developed its capacity to make sure that what needs doing is done, within the exiting mainly fee enterprise system (Economy A.) Over time experience would indicate the best balance between the two, and whether there was any need for the market sector.

There would be many free” goods from the commons, a large non-cash sector involving sharing, giving, helping and voluntary working bees, and almost no finance sector. Small public banks with elected boards would hold savings and arrange loans for maintenance or restructuring.  Some people might pay all their tax by extra contributions to the community working bees. Communities would ensure that there was no unemployment or poverty, no isolation or exclusion, all felt secure, and that all had a livelihood, a worthwhile and valued contribution to make to the town. Because the goal would be material lifestyles that were frugal but sufficient, involving for instance small and very low cost earth built houses, on average people might need to work for money only two days a week. It can be argued that the quality of life would be higher than it is for most people in rich countries today. Lest these ideas seem fanciful, they describe the ways many thousands now live in ecovillages and Transition Towns.

Beyond the town or suburban level there would be regional and national economies, and larger cities containing universities, steel works, and large scale production, e.g., of railway equipment, but their activities would be greatly reduced, and re oriented to provisioning the local economies. There would be little international trade or travel. The termination of the present vast expenditure on wasteful production would enable the amount spent on socially useful R and to be significantly increased.

A detailed analysis of an Australian suburban geography (Trainer, 2016) concludes that technically it would be relatively easy to carry out the very large reductions and restructurings indicated, possibly cutting in energy and dollar costs by around 90%.

It is obvious that the Simpler Way vision could not be realised unless there was enormous “cultural” change, especially away from competitive, acquisitive, maximising individualism and towards frugality, collectivism, sufficiency and responsible citizenship. Fortunately there is now increasing recognition that pursuing ever greater material wealth and GDP is not a promising path to greater human welfare. In a zero-growth settlement there could be no concern with the accumulation of wealth; all would have to be content with stable and secure circumstances, to enjoy non-material life satisfactions, and to be aware that their “welfare” depended not on their individual monetary wealth but on public wealth, i.e., on their town’s infrastructures, systems, edible landscapes, free concerts, working bees, committees, leisure resources, solidarity and morale.

Thus from The Simpler Way perspective the solution to global problems is not a technical issue; it is a value issue. We have all the technology we need to create admirable societies and idyllic lives. But this can’t be done if growth and affluence remain the overriding goals.

At present there would seem to be little chance that a transition to The Simpler Way will be achieved, but that is not central here; the issue is whether this vision or that of the ecomodernist makes more sense.

Mineral resources and the limits to growth

29 09 2013

I thought long and hard about reproducing this remarkable article here…….  It’s rather longer than anything I

Ugo Bardi

Ugo Bardi

usually put up, and I was concerned about copyright, but found nothing on the original website where this was published that says I can’t do it…… and I expect no one at resilience.org objects to ensuring the spread of this important message.

Five years ago, I published a very short item on roughly the same concept.  But I’m no Ugo Bardi…..  So make yourself a good cuppa your favourite poison, and enjoy….

 

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 

So, ladies and gentleman, let me start with this recent book of mine. It is titled “The Plundered Planet.”  You can surely notice that it is not titled “The Developed Planet” or “The Improved Planet.”  Myself and the co-authors of the book chose to emphasize the concept of “Plundering”; of the fact that we are exploiting the resources of our planet as if they were free for us for the taking; that is, without thinking of the consequences.   And the main consequence, with which we are concerned here is called “depletion,” even though we have to keep in mind the problem of pollution as well.

Now, there have been many studies on the question of depletion, but “The Plundered Planet” has a specific origin, and I can show it to you. Here it is.

It is the rather famous study that was published in 1972 with the title “The Limits to Growth”.  It was one of the first studies that attempted to quantify depletion and its effects on the world’s economic system.  It was a complex study based on the best available data at the time and that used the most sophisticated computers available to study how the interaction of various factors would affect parameters such as industrial production, agricultural production, population and the like.  Here are the main results of the 1972 study, the run that was called the “base case” (or “standard run”).  The calculations were redone in 2004, finding similar results.  

As you can see, the results were not exactly pleasant to behold.  In 1972, the study saw a slowdown of the world’s main economic parameters that would take place within the first two decades of the 21st century.  I am sure that you are comparing, in your minds, these curves with the present economic situation and you may wonder whether these old calculations may be turning out to be incredibly good.  But I would also like to say that these curves are not – and never were – meant to be taken as specific predictions.  No one can predict the future, what we can do is to study tendencies and where these tendencies are leading us.  So, the main result of the Limits to Growth study was to show that the economic system was headed towards a collapse at some moment in the future owing to the combined effect of depletion, pollution, and overpopulation.  Maybe the economic problems we are seeing nowadays are a prelude to the collapse seen by this model, maybe not – maybe the predicted collapse is still far away in the future.  We can’t say right now. 

In any case, the results of the study can be seen at least worrisome.  And a reasonable reaction when the book came out in 1972 would have been to study the problem in greater depth – nobody wants the economy to collapse, of course.  But, as you surely know, the Limits to Growth study was not well received.  It was strongly criticized, accused of having made “mistakes” of all kinds and at times to be part of a worldwide conspiracy to take control of the world and to exterminate most of humankind.  Of course, most of this criticism had political origins.  It was mostly a gut reaction: people didn’t like these results and sought to find ways to demonstrate that the model was wrong (or the data, or the approach, or something else).  If they couldn’t do that, they resorted to demonizing the authors – that’s nothing now; I described it in a book of mine “Revisiting the limits to growth“.

Nevertheless, there was a basic criticism of the “Limits” study that made sense.  Why should one believe in this model?  What are exactly the factors that generate the expected collapse?  Here, I must say, the answer often given in the early times by the authors and by their supporters wasn’t so good.  What the creators of the models said was that the model made sense according to their views and they could show a scheme that was this (from the 1972 Italian edition of the book):

Now, I don’t know what do you think of it; to me it looks more or less like the map of the subway of Tokyo, complete with signs in kanji characters.  Not easy to navigate, to say the least.  So, why did the authors create this spaghetti model?  What was the logic in it?  It turns out that the Limits to Growth model has an internal logic and that it can be explained in thermodynamic terms.  However, it takes some work to describe the whole story.  So, let me start with the ultimate origin of these models:

If you have studied engineering, you surely recognize this object.  It is called a “governor” and it is a device developed in 19th century to regulate the speed of steam engines.  It turns with the engine, and the arms open or close depending on speed.  In so doing, the governor closes or opens the valve that sends steam into the engine.  It is interesting because it is the first self-regulating device of this kind and, at its time, it generated a lot of interest.  James Clerk Maxwell himself studied the behaviour of the governor and, in 1868, he came up with a set of equations describing it. Here is a page from his original article

I am showing you these equations just to let you note how these systems can be described by a set of correlated differential equations.  It is an approach that is still used and today we can solve this kind of equations in real time and control much more complex systems than steam engines.  For instance, drones.

You see here that a drone can be controlled so perfectly that it can hold a glass without spilling the content. And you can have drones playing table tennis with each other and much more.  Of course they are also machines designed for killing people, but let’s not go into that.  The point is that if you can solve a set of differential equations, you can describe – and also control – the behaviour of quite complex systems.

The work of Maxwell so impressed Norbert Wiener, that it led him to develop the concept of “cybernetics”

We don’t use so much the term cybernetics today.  But the ideas that started from the governor study by Maxwell were extremely fecund and gave rise to a whole new field of science.  When you use these equations for controlling mechanical system, you use the term “control theory.”  But when you use the equations for study the behaviour of socio-economic systems, you use the term “system dynamics”

System dynamics is something that was developed mainly by Jay Wright Forrester in the 1950s and 1960s, when there started to exist computers powerful enough to solve sets of coupled differential equations in reasonable times.  That generated a lot of studies, including “The Limits to Growth” of 1972 and today the field is alive and well in many areas.

A point I think is important to make is that these equations describe real world systems and real world systems must obey the laws of thermodynamics.  So, system dynamics must be consistent with thermodynamics. It does.  Let me show you a common example of a system described by system dynamics: practitioners in this field are fond of using a bathub as an example:

On the right you have a representation of the real system, a bathtub partly filled with water.  On the left, its representation using system dynamics.  These models are called “stock and flow”, because you use boxes to represent stocks (the quantity of water in the tub) and you use double edged arrows to indicate flows.  The little butterfly like things indicate valves and single edged arrows indicate relationship.

Note that I used a graphic convention that I like to use for my “mind sized” models.  That is, I have stocks flowing “down”, following the dissipation of thermodynamic potential.  In this case what moves the model is the gravitational potential; it is what makes water flow down, of course.  Ultimately, the process is driven by an increase in entropy and I usually ask to my students where is that entropy increases in this system.  They usually can’t give the right answer.  It is not that easy, indeed – I leave that to you as a little exercise

The model on the left is not simply a drawing of box and arrows, it is made with a software called “Vensim” which actually turns the model “alive” by building the equations and solving them in real time.  And, as you may imagine, it is not so difficult to make a model that describes a bathtub being filled from one side and emptied from the other. But, of course, you can do much more with these models.  So, let me show a model made with Vensim that describes the operation of a governor and of the steam engine.

Before we go on, let me introduce a disclaimer.  This is just a model that I put together for this presentation. It seems to work, in the sense that it describes a behaviour that I think is correct for a governor (you can see the results plotted inside the boxes).  But it doesn’t claim to be a complete model and surely not the only possible way to make a system dynamics model of a governor.  This said, you can give a look to it and notice a few things.  The main one is that we have two “stocks” of energy: one for the large wheel of the steam energy, the other for the small wheel which is the governor.  In order to provide some visual sense of this difference in size, I made the two boxes of different size, but that doesn’t change the equations underlying the model.  Note the “feedback”, the arrows that connect flows and stock sizes.  The concept of feedback is fundamental in these models.

Of course, this is also a model that is compatible with thermodynamics.  Only, in this case we don’t have a gravitational potential that moves the system, but a potential based on temperature differences.  The steam engine works because you have this temperature difference and you know the work of Carnot and the others who described it.  So, I used the same convention here as before; thermodynamic potential are dissipated going “down” in the model’s graphical representation

Now, let me show you another simple model, the simplest version I can think of a model that describes the exploitation of non renewable resources:

It is, again, a model based on thermodynamics and, this time, driven by chemical potentials.  The idea is that the “resources” stock as a high chemical potential in the sense that it may be thought as, for instance, crude oil, which spontaneously combines with oxygen to create energy.  This energy is used by human beings to create what I can call “capital” – the sum of everything you can do with oil; from industries to bureaucracies.

On the right, you can see the results that the model provides in terms of the behaviour as a function of time of the stock of the resources, their production, and the capital stock.  You may easily notice how similar these curves are to those provided by the more complex model of “The Limits to Growth.”  So, we are probably doing something right, even with this simple model.

But the point is that the model works!  When you apply it to real world cases, you see that its results can fit the historical data.  Let me show you an example:

This is the case of whaling in 19th century, when whale oil was used as fuel for lamps, before it became common to use kerosene.  I am showing you this image because it is the first attempt I made to use the model and I was surprised to see that it worked – and it worked remarkably well.  You see, here you have two stocks: one is whales, the other is the capital of the whaling industry that can be measured by means of a proxy that is the total tonnage of the whaling fleet.  And, as I said, the model describes very well how the industry grew on the profit of killing whales, but they killed way too many of them.  Whales are, of course, a renewable resource; in principle.  But, of course, if too many whales are killed, then they don’t have enough time to reproduce and they behave as a non-renewable resource.  Biologists have determined that at the end of this fishing cycle, there were only about 50 females of the species being hunted at that time.  Non renewable, indeed!

So, that is, of course, one of the several cases where we found that the model can work.  Together with my co-workers, we found that it can work also for petroleum extraction, as we describe in a paper published in 2009 (Bardi and Lavacchi).  But let me skip that – the important thing is that the model works in some cases but, as you would expect, not in all. And that is good – because what you don’t want is a “fit-all” model that doesn’t tell you anything about the system you are studying.  Let’s say that the model reproduces what’s called the “Hubbert model” of resource exploitation, which is a purely empirical model that was proposed more than 50 years ago and that remains a basic one in this kind of studies: it is the model that proposes that extraction goes through a “bell-shaped” curve and that the peak of the curve, the “Hubbert peak” is the origin of the concept of “peak oil” which you’ve surely heard about.  Here is the original Hubbert model and you see that it has described reasonably well the production of crude oil in the 48 US lower states.

Now, let’s move on a little.  What I have presented to you is a very simple model that reproduces some of the key elements of the model used for “The Limits to Growth” study but it is of course a very simplified version.  You may have noted that the curves for industrial production of the Limits to Growth tend to be skewed forward and this simple model can’t reproduce that.  So, we must move one step forward and let me show you how it can be done while maintaining the basic idea of a “thermodynamic cascade” that goes from higher potentials to lower potentials.  Here is what I’ve called the “Seneca model”


You see that I added a third stock to the system.   In this case I called it “pollution”; but you might also call it, for instance, “bureaucracy” or may be even “war”.  It is any stock that draws resource from the “Capital” (aka, “the economy”) stock.  And the result is that the capital stock and production collapse rather rapidly; this is what I called “the Seneca effect”; from the roman philosopher Lucius Anneaus Seneca who noted that “Fortune is slow, but ruin is rapid”.

For this model, I can’t show you specific historical cases – we are still working on this idea, but it is not easy to make quantitative fittings because the model is complicated.  But there are cases of simple systems where you see this specific behaviour, highly forward skewed curves – caviar fishing is an example.  But let’s not go there right now.

What I would like to say is that you can move onward with this idea of cascading thermodynamic potentials and build up something that may be considered as a simplified version of the five main stocks taken into account in the “Limits to Growth” calculations.  Here it is

Now, another disclaimer: I am not saying that this model is equivalent to that of the Limits to Growth, nor that it is the only way to arrange stocks and flows in order to produce similar results to the one obtained by the Limits to Growth model.  It is here just to show to you the logic of the model.  And I think you can agree, now, that there is one.  The “Limits” model is not just randomly arranged spaghetti, it is something that has a deep logic based on thermodynamics.  It describes the dissipation of a cascade of thermodynamic potentials.

In the end, all these model, no matter how you arrange their elements, tend to generate similar basic results: the bell shaped curve; the one that Hubbert had already proposed in 1956

The curve may be skewed forward or not, but that changes little on the fact that the downside slope is not so pleasant for those who live it.

Don’t expect this curve to be a physical law; after all it depend on human choices and human choices may be changed.  But, in normal conditions, human beings tend to follow rather predictable patterns, for instance exploiting the “easy” resources (those which are at the highest thermodynamic potential) and then move down to the more difficult ones.  That generates the curve.

Now, I could show you many examples of the tendency of real world systems to follow the bell shape curve.  Let me show you just one; a recent graph recently made by Jean Laherrere.

These are data for the world’s oil production.  As you can see, there are irregularities and oscillations.  But note how, from 2004 to 2013, we have been following the curve: we move on a predictable path.  Already in 2004 we could have predicted what would have been today’s oil production.  But, of course, there are other elements in this system.  In the figure on the right, you can see also the appearance of the so-called “non-conventional” oil resources, which are following their own curve and which are keeping the production of combustible liquids (a concept slightly different from that of “crude oil) rather stable or slightly increasing.  But, you see, the picture is clear and the predictive ability of these models is rather good even though, of course, approximate.

Now, there is another important point I’d like to make.  You see, these models are ultimately based on thermodynamics and there is an embedded thermodynamic parameter in the models that is called EROI (or ERoEI) which is the energy return for the energy invested. It is basically the decline in this parameter that makes, for instance, the extraction of oil gradually producing less energy and, ultimately, becoming pointless when the value of the ERoEI goes below one.  Let me show you an illustration of this concept:

You see?  The data you usually read for petroleum production are just that: how much petroleum is being produced in terms of volume.  There is already a problem with the fact that not all petroleums are the same in the sense of energy per unit volume, but the real question is the NET energy you get by subtracting the energy invested from the energy produced.  And that, as you see, goes down rapidly as you move to more expensive and difficult resources.  For EROEIs under about 20, the problem is significant and below about 10 it becomes serious.  And, as you see, there are many energy resources that have this kind of low EROEI.  So, don’t get impressed by the fact that oil production continues, slowly, to grow.  Net energy is the problem and many things that are happening today in the world seem to be related to the fact that we are producing less and less net energy.  In other words, we are paying more to produce the same.  This appears in terms of high prices in the world market.

Here is an illustration of how prices and production have varied during the past decades from the blog “Early Warning” kept by Stuart Staniford.

And you see that, although we are able to manage a slightly growing production, we can do so only at increasingly high prices.  This is an effect of increasing energy investments in extracting difficult resources – energy costs money, after all.

So, let me show you some data for resources that are not petroleum.  Of course, in this case you can’t speak in terms of ERoEI; because you are not producing energy.  But the problem is the same, since you are using fossil fuels to produce most of the commodities that enter the industrial system, and that is valid also for agriculture. Here are some data.

Food production worldwide is still increasing, but the high costs of fossil fuels are causing this increase in prices.  And that’s a big problem because we all know that the food demand is highly inelastic – in plain words you need to eat or you die.  Several recent events in the world, such as wars and revolutions in North Africa and Middle East have been related to these increases in food prices.

Now, let me go to the general question of mineral production.  Here, we have the same behaviour: most mineral commodities are still growing in terms of extracted quantities, as you can see here (from a paper by Krausmann et al, 2009 http://dx.doi.org/10.1016/j.ecolecon.2009.05.007)

These data go up to 2005 – more recent data show signs of plateauing production, but we don’t see clear evidence of a peak, yet. This is bad, because we are creating a climate disaster. As you see from the most recent data, CO2 are still increasing in a nearly exponential manner

 

But the system is clearly under strain. Here are some data relative to the average price index for aluminium, copper, gold, iron ore, lead, nickel, silver, tin and zinc (adapted from a graphic reported by Bertram et al., Resource Policy, 36(2011)315)

So, you see, there has been this remarkable “bump” in the prices of everything and that correlates well with what I was arguing before: energy costs more and, at the same time, energy requirements are increasing because of ore depletion.  At present, we are still able to keep production stable or even slowly increasing, but this is costing society tremendous sacrifices in terms of reducing social services, health care, pensions and all the rest.  And, in addition, we risk destroying the planetary ecosystem because of climate change.

Now I can summarize what I’ve been saying and get to the take-home point which, I think can be expressed in a single sentence “Mining takes energy

Of course, many people say that we are so smart that we can invent new ways of mining that don’t require so much energy.  Fine, but look at that giant wheel, above, used to extract coal in the mine of Garzweiler in Germany.  Think of how much energy you need to make that wheel; do you think you could use an i-pad, instead?

In the end, energy is the key of everything and if we want to keep mining, and we need to keep mining, we need to be able to keep producing energy.  And we need to obtain that energy without fossil fuels. That’s the concept of the “Energy Transition”

Here, I use the German term “Energiewende” which stands for “Energy Transition”. And I have also slightly modified the words by Stanley Jevons, he was talking about coal, but the general concept of energy is the same.  We need to go through the transition, otherwise, as Jevons said long ago, we’ll be forced to return to the “laborious poverty” of older times.

That doesn’t mean that the times of low cost mineral commodities will ever return but we should be able to maintain a reasonable flux of mineral commodities into the industrial system and keep it going.  But we’ll have to adapt to less opulent and wasteful life as the society of “developed” countries has been accustomed to so far.  I think it is not impossible, if we don’t ask too much:
