The green car myth

How government subsidies make the white elephant on your driveway look sustainable

And this comes on top of this article that describes how just making electric cars’ battery packs is equivalent to eight years worth of driving conventional happy motoring.

I have written before about the problems with bright green environmentalism. Bright greens suggest that various technological innovations will serve to reduce carbon dioxide emissions enough to avoid catastrophic global warming and other environmental problems. There are a variety of practical problems that I outlined there, including the fact that most of our economic activities are hitting physical limits to energy efficiency.

The solution lies in accepting that we can not continue to expand our economies indefinitely, without catastrophic consequences. In fact, catastrophic consequences are in all likelihood already unavoidable, if we believe the warnings of prominent climatologists who claim that a two degree temperature increase is sufficient to cause significant global problems.

It’s easy to be deceived however and assume that we are in the process of a transition towards sustainable green technologies. The problem with most green technologies is that although their implementation on a limited scale is affordable, they have insufficient scalability to enable a transition away from fossil fuels.

Part of the reason for this limited scalability is because users of “green” technology receive subsidies and do not pay certain costs which users of “grey” technology have to shoulder as a result. As an example, the Netherlands, Norway and many other nations waive a variety of taxes for green cars, taxes that are used to maintain the network of roads that these cars use. As the share of green cars rises, grey cars will be forced to shoulder increasingly higher costs to pay for the maintenance of road networks.

It’s inevitable that these subsidies will be phased out. The idea of course is that after providing an initial gentle push, the transition towards more green driving will have reached critical mass and prove itself sustainable without any further government subsidies. Unfortunately, that’s unlikely to occur. We’ve seen a case study of what happens when subsidies for green technologies are phased out in Germany. After 2011, the exponential growth in solar capacity rapidly came to a stop, as new installs started to drop. By 2014, solar capacity in Germany had effectively stabilized.1 Peak capacity of solar is now impressively high, but the amount of solar energy produced varies significantly from day to day. On bad days, solar and wind hardly contribute anything to the electricity grid.

Which brings us to the subject of today’s essay: The green car. The green car has managed to hide its enormous price tag behind a variety of subsidies, dodged taxes and externalities it has imposed upon the rest of society. Let us start with the externalities. Plug-in cars put significant strain on the electrical grid. These are costs that owners of such cars don’t pay themselves. Rather, power companies become forced to make costs to improve their grid, to avoid the risk of blackouts, costs that are then passed on to all of us.

When it comes to the subsidies that companies receive to develop green cars, it’s important not just to look at the companies that are around today. This is what is called survivorship bias. We focus on people who have succeeded and decide that their actions were a good decision to take. Everyone knows about the man who became a billionare by developing Minecraft. As a result, there are droves of indie developers out there hoping to produce the next big game. In reality, most of them earn less than $500 a year from sales.2

Everyone has heard of Tesla or of Toyota’s Prius. Nobody hears of the manufacturers who failed and went bankrupt. They had to make costs too, costs that were often passed on to investors or to governments. Who remembers Vehicle Production Group, or Fisker automotive? These are companies that were handed 193 million and 50 million dollar in loans respectively by the US Federal government, money the government won’t see again because the companies went bankrupt.3 This brings the total of surviving car manufacturers who received loans from the government to three.

To make matters worse, we don’t just subsidize green car manufacturers. We subsidize just about the entire production chain that ultimately leads to a green car on your driveway. Part of the reason Fisker automotive got in trouble was because its battery manufacturer, A123 Systems, declared bankruptcy. A123 Systems went bankrupt in 2012, but not before raising 380 million dollar from investors in 2009 and receiving a 249 million dollar grant from the U. S. department of energy back in 2010.

Which brings us to a de facto subsidy that affects not just green cars, but other unsustainable projects as well: Central bank policies. When interest rates are low, investors have to start searching for yield. They tend to find themselves investing in risky ventures, that may or may not pay off. Examples are the many shale companies that are on the edge of bankruptcy today. This could have been anticipated, but the current financial climate leaves investors with little choice but to invest in such risky ventures. This doesn’t just enable the growth of a phenomenon like the shale oil industry affects green car companies as well. Would investors have poured their money into A123 Systems, if it weren’t for central bank policies? Many might have looked at safer alternatives.

One company that has benefited enormously from these policies is Tesla. In 2008, Tesla applied for a 465 million dollar loan from the Federal government. This allowed Tesla to produce its car, which then allows Tesla to raise 226 million in an IPO in June 2010, where Tesla receives cash from investors willing to invest in risky ventures as a result of central bank policies. A $7,500 tax credit then encourages sales of Tesla’s Model S, which in combination with the money raised from the IPO allows Tesla to pay off its loan early.

In 2013, Tesla then announces that it has made an 11 million dollar profit. Stock prices go through the roof, as apparently they have succeeded at the task of the daunting task of making green cars economically viable. In reality, Tesla made 68 million dollar that year selling its emission credits to other car companies, without which, Tesla would have made a loss.

Tesla in fact receives $35,000 dollar in clean air credits for every Model S that it sells to customers, which in total was estimated to amount to 250 million dollar in 2013.4 To put these numbers in perspective, buying a Model S can cost anywhere around $70,000, so if the 35,000 dollar cost was passed on to the customer, prices would rise by about 50%, not including whatever sales tax applies when purchasing a car.

We can add to all of this the 1.2 billion of subsidy in the form of tax exemptions and reduced electricity rates that Tesla receives for its battery factory in Nevada.5 The story gets even better when we arrive at green cars sold to Europe, where we find the practice of “subsidy stacking”. The Netherlands exempts green cars from a variety of taxes normally paid upon purchase. These cars are then exported to countries like Norway, where green cars don’t have to pay toll and are allowed to drive on bus lanes.6

For freelancers in the Netherlands, subsidies for electrical cars have reached an extraordinarily high level. Without the various subsidies the Dutch government created to increase the incentive to drive an electrical car, a Tesla S would cost 94.010 Euro. This is a figure that would be even higher of course, if Dutch consumers had to pay for the various subsidies that Tesla receives in the United States. After the various subsidies provided by the Dutch government for freelance workers, Dutch consumers can acquire a Tesla S at a price of just 25,059 Euro.7

The various subsidies our governments provide are subsidies we all end up paying for in one form or another. What’s clear from all these numbers however is that an electric car is currently nowhere near a state where it could compete with a gasoline powered car in a free unregulated market, on the basis of its own merit.

The image that emerges here is not one of a technology that receives a gentle nudge to help it replace the outdated but culturally entrenched technology we currently use, but rather, of a number of private companies that compete for a variety of subsidies handed out by governments who seek to plan in advance how future technology will have to look, willfully ignorant of whatever effect physical limits might have on determining which technologies are economically viable to sustain and which aren’t.

After all, if government were willing to throw enough subsidies at it, we could see NGO’s attempt to solve world hunger using caviar and truffles. It wouldn’t be sustainable in the long run, but in the short term, it would prove to be a viable solution to hunger for a significant minority of the world’s poorest. There are no physical laws that render such a solution impossible on a small scale, rather, there are economic laws related to scalability that render it impossible.

Similarly, inventing an electrical car was never the problem. In 1900, 38% of American cars ran on electricity. The reason the electrical car died out back then was because it could not compete with gasoline. Today the problem consists of how to render it economically viable and able to replace our fossil fuel based transportation system, without detrimentally affecting our standard of living.

This brings us to the other elephant, the one in our room rather than our driveway. The real problem here is that we wish to sustain a standard of living that was built with cheap natural resources that are no longer here today. Coping with looming oil shortages will mean having to take a step back. The era where every middle class family could afford to have a car is over. Governments would be better off investing in public transport and safe bicycle lanes.

The problem America faces however, is that there are cultural factors that prohibit such a transition. Ownership of a car is seen as a marker of adulthood and the type of car tells us something about a man’s social status. This is an image car manufacturers are of course all too happy to reinforce through advertising. Hence, we find a tragic example of a society that wastes its remaining resources on false solutions to the crisis it faces.

How “Green” is Lithium?

17 04 2016

Originally published on the KITCO website in 2014….. interesting how this makes no mention of NiFe batteries, they are simply ‘under the radar’……

 

The market for battery electric and hybrid vehicles is growing slowly but steadily – from 0.4% in 2012 to 0.6% in 2013 and 0.7% in 2014 (year-to-date) in the United States alone.

Consumers buy these vehicles despite lower gas prices out of a growing conscience and concern for the environment. With this strong attraction to alternative energy, grows the demand for lithium, which is predominantly mined and imported from countries like Bolivia, Chile, China and Argentina.

Within the U.S., only Nevada, future home of Tesla’s new “Gigafactory” for batteries, produces lithium. However, the overall ecological impact of lithium ion batteries remains somewhat unclear, as does the “well-to-wheel” effort and cost to recharge such batteries.

To fully grasp the relevance and environmental impact of lithium it is important to note that lithium ion batteries are also found in most mobile phones, laptop computers, wearable electronics and almost anything else powered by rechargeable batteries.

Dozens of reports are available on the ecological impact of lithium mining. Unfortunately, many of them are influenced by the perspective of the organizations or authors releasing them. Reducing the available information to studies carried out by government bodies and research institutes around the world, a picture emerges nonetheless:

  • Elemental lithium is flammable and very reactive. In nature, lithium occurs in compounded forms such as lithium carbonate requiring chemical processing to be made usable.
  • Lithium is typically found in salt flats in areas where water is scarce. The mining process of lithium uses large amounts of water. Therefore, on top of water contamination as a result of its use, depletion or transportation costs are issues to be dealt with. Depletion results in less available water for local populations, flora and fauna.
  • Toxic chemicals are used for leaching purposes, chemicals requiring waste treatment. There are widespread concerns of improper handling and spills, like in other mining operations around the world.
  • The recovery rate of lithium ion batteries, even in first world countries, is in the single digit percent range. Most batteries end up in landfill.
  • In a 2013 report, the U.S. Environmental Protection Agency (EPA) points out that nickel and cobalt, both also used in the production of lithium ion batteries, represent significant additional environmental risks.

A 2012 study titled “Science for Environment Policy” published by the European Union compares lithium ion batteries to other types of batteries available (lead-acid, nickel-cadmium, nickel-metal-hydride and sodium sulphur). It concludes that lithium ion batteries have the largest impact on metal depletion, suggesting that recycling is complicated. Lithium ion batteries are also, together with nickel-metal-hydride batteries, the most energy consuming technologies using the equivalent of 1.6kg of oil per kg of battery produced. They also ranked the worst in greenhouse gas emissions with up to 12.5kg of CO2 equivalent emitted per kg of battery. The authors do point out that “…for a full understanding of life cycle impacts, further aspects of battery use need to be considered, such as length of usage, performance at different temperatures, and ability to discharge quickly.”

Technology will of course improve, lithium supplies will be sufficient for the foreseeable future, and recycling rates will climb. Other issues like the migration of aging cars and electronic devices to countries with less developed infrastructures will, however, remain. As will the reality of lithium mining and processing. It is therefore conceivable that new battery technologies (sea water batteries or the nano-flowcell, for instance) will gain more importance in years to come, as will hydrogen fuel cells.

We will report about the pros and cons of each of these alternatives in future issues of Tech Metals Insider.

Energy storage for the Tasmanian Project

I’ve done it.  I’ve ordered my Nickel Iron batteries and Victron charger/inverter. Once I’ve ironcoreascertained whether or not I can afford it, I will purchase a second Victron for future backup, fingers crossed the economy (and our funds!) hold out long enough.  The batteries, a 48V 200Ah bank, won’t get here from Russia for another six or so weeks, and when they do, I’ll post more about the installation.

Victron inverter/charger

What really got me started re posting this was the extraordinary episode of Catalyst aired on ABC TV last night….

Anyone watching this will have been totally taken over by techno utopianism of the highest quality.  Dr Jonica Newby is a veterinarian, and unfortunately doesn’t seem to know the difference between power and energy, but maybe I’m just splitting hairs….. it was nonetheless frustrating to constantly hear battery banks rated in kW rather than kWh, big difference….

The “we’ll be saved by these batteries” gushing coming from everyone’s mouths in this show was only interrupted for a few seconds when one commentator expressed his doubt over the financial viability of the very first Tesla power wall installed in Australia.  He asked how this was remotely viable when the payback was 23 years, and the equipment was only warranted for 10? Which was swiftly glossed over for the remaining 25 minutes and never mentioned again…..

Worse, the evangelical fervour used to extol the virtues of Lithium Ion batteries, a technology that I am certain will disappoint a lot of owners in the future, bordered on religion……  think back to how long batteries in your laptops and cell phones last, and wonder how long before all that stuff ends up on landfill.

From Computer World:

Dell plans to recycle however many of the 4.1 million recalled batteries that customers turn in (see Dell battery recall not likely to have big environmental impact), but what happens to the other 2 billion lithium ion batteries which will be sold this year? Most will last for 300 to 500 full recharges (one to three years of use) before failing and ending up in your local municipal landfill or incinerator.

Europeans have a dimmer view of landfilling lithium ion batteries. “There is always potential contamination to water because they contain metals,” says Daniel Cheret, general manager at Belgium-based Umicore Recycling Solutions. The bigger issue is a moral one: the products have a recycling value, so throwing away 2 billion batteries a year is just plain wasteful – especially when so many American landfills are running out of space. “It’s a pity to landfill this material that you could recover,” Charet says. He estimates that between 8,000 and 9,000 tons of cobalt is used in the manufacture of lithium ion batteries each year. Each battery contains 10 to 13% cobalt by weight. Umicore recyles all four metals used in lithium ion batteries.

The reason why more lithium ion batteries aren’t recycled boils down to simple economics: the scrap value of batteries doesn’t amount to much – perhaps $100 per ton, Cheret says. In contrast, the cost of collecting, sorting and shipping used batteries to a recycler exceeds the scrap value, so batteries tend to be thrown away. Unfortunately, the market does not factor in the social cost of disposal, nor does it factor in the fact that recycling metals such as cobalt has a much lower economic and environmental cost than mining raw materials. So we throw them away by the millions.

To be fair, Professor Thomas Maschmeyer also introduced zinc bromide battery technology to the show, and it sounds impressive, with very fast charging times, which by the way is irrelevant to home battery charging. Amusingly, our veterinarian presenter had never heard of gel cells and looked mightily impressed with that too.  It’s easy to be impressed with technology you’re not familiar with, or don’t understand I guess….. and a timeline of 10 or 20 years was mentioned, as if we actually have 10 or 20 years to solve our climate and energy predicaments.

As was to be expected, the main theme of the show was all about how much money could be made from this, not how it was going to save us from climate change or anything else important.  I could not stop laughing when, poised over a computer monitor, Josh Byrne of Gardening Australia fame makes five cents from exporting battery power to his electricity supplier…… what a waste of batteries. How anyone can think that shortening the life of one’s battery bank for five cents is worthwhile truly staggers me. Especially when the service provider then sells it to his neighbours for four times that much!

To his credit, I hasten to add, Josh Byrne has built a 10 star energy efficient house which, powered by just 3kW (when just about everyone these days installs five…) appears to be managing almost as well as we used to in Queensland. I think a program devoted to this aspect of his energy management would be far more useful than the one being discussed at the moment…

Josh’s house project

There was, as usual, much talk about how we could go fossil fuel free, without any acknowledgement whatsoever that all the stuff that goes into these magic boxes of tricks have to be mined, refined, shipped, manufactured, and installed, using….. fossil fuels of course!!  Nor was there any mention of where the money to make all this stuff would come from.

Fascinatingly, the ‘big three’ electricity suppliers in Australia are getting in on the act. Why they would do this when they are constantly expressing their anti renewables positions is puzzling.  Could it be more ‘we’re greener than thou’?

I remain totally baffled by this race to the bottom.

UPDATE:

I have just been pointed to this paper written by Peter J. DeMar, Battery Research and Testing, Inc. Oswego, NY, USA

pjd@batteryresearch.com

They actually managed to revive 85+ year old NiFe batteries to close to their original capacity, even though most of them had been abused beyond belief….. they’re going to keep them going for another fifteen years, just to show if Edison’s original claim that they would last 100 years isn’t mere marketing…..

They concluded…….:

This find of these old Thomas Edison Nickel-Iron cells has been quite an education for us at Battery Research and Testing, as our work for the past 29 years has been primarily with lead acid and some Nickel-Cadmium, but with nothing of the age of these cells. In fact the oldest lead acid cells that we have load tested and that were still functional were old Exide Manchex strings that were 42 years old, and it appears that the only existing lead acid cells that might be able to be functional at 40 years of age are the Bell developed round cells for Telecom applications.

What we have learned has opened up our minds to explore possibilities for this design long life design cell. It would sure seem that any site that has a requirement for a long life battery that will tolerate abusive conditions would consider the total life costs of these type cells and see which works out to be the most cost effective.

Electric vehicle batteries ‘already cheaper than 2020 projections’

25 03 2015

As the cost of everything seems to be plummeting right now, I, who always plays the devil’s advocate and sceptic of the first order, find it hard to not wonder if Nicole Foss’ much vaunted deflationary spiral is not already underway.  Just this morning I found out that the US coal industry is in trouble.  Then, reports of worsening problems are finally surfacing about the oil industry.  As we all know here at DTM, without a profitable fossil fuel industry, absolutely nothing else will eventuate when it comes to the alternatives……..  so what to make of this?  All I can say is, hang onto your hat, because the ride will be interesting.

The US coal market is crashing in what analysts warn is a sign of things to come for other fossil fuel markets.

At least 26 coal producers have gone bankrupt in the last three years, the Carbon Tracker Initiative think-tank found.

Others including Peabody Energy, the world’s largest private coal company, have lost 80% of their share value.

“Cheap gas has knocked coal off its feet, and the need to improve air quality and ever-lower renewables costs has kept coal down for the count,” said report co-author Luke Sussams.

Meanwhile, demand growth from Asia has been slower than expected. China’s coal consumption fell 3% in 2014 as the country sought to tackle increasingly severe air pollution in its cities.

AND….

In the latest week, drillers idled another 41 oil rigs, according to Baker Hughes. Only 825 rigs were still active, down 48.7% from October. In the 23 weeks since, drillers have idled 784 oil rigs, the steepest, deepest cliff-dive in the history of the data:

US-rig-count_1988_2015-03-20=oil

The number of rigs drilling for natural gas dropped by 15 to 242, the lowest rig count since March 1992 and down 85% from its peak in 2008.

By Simon Evans

The cost of electric vehicle battery packs is falling so rapidly they are probably already cheaper than expected for 2020, according to a new study in Nature Climate Change.

Electric vehicles remain more expensive than combustion-engine equivalents, largely because of battery costs. In 2013 the International Energy Agency estimated cost-parity could be reached in 2020, with battery costs reaching $300* per kilowatt-hour of capacity.

But market-leading firms were probably already producing cheaper batteries last year, says today’s new research. It says its figures are “two to four times lower than many recent peer-reviewed papers have suggested”.

High costs, falling

Even though the  EU electric vehicle market grew by 37% year on year in 2014, it still made up less than 1% of total sales. High cost is a major reason why electric vehicles have failed to break through, alongside range and a lack of recharging infrastructure.

The new research is based on a review of 85 cost estimates in peer-reviewed research, agency estimates, consultancy and industry reports, news reports covering the views of industry representatives and experts and finally estimates from leading manufacturers.

It says industry-wide costs have fallen from above $1000 per kilowatt-hour in 2007 down to around $410 in 2014, a 14% annual reduction (blue marks, below). Costs for market-leading firms have fallen by 8% per year, reaching $300 per kilowatt hour in 2014 (green marks).

Figure 1: Cost estimates and future projections for EV battery packs, measured in $US per kilowatt hour of capacity. Each mark on the chart represents a documented estimate reviewed by the study.

Source: Nykvist et al. (2015).

For the market-leading firms, shown in green on the chart above, costs last year were already at the bottom end of projections for 2020 (yellow triangles).

The paper estimates prices will fall further to around $230 per kilowatt-hour in 2017-18, “on a par with the most optimistic future estimate among analysts”. The crossover point where electric cars become cheapest depends on electricity costs, vehicle taxes and prices at the pump.

In the US, with current low oil prices, battery packs would need to fall below $250 per kilowatt-hour for electric cars to become competitive, the study says. Behavioural barriers to electric vehicle uptake present additional hurdles to widespread adoption.

The paper says:

“If costs reach as low as $150 per kilowatt-hour this means that electric vehicles will probably move beyond niche applications and begin to penetrate the market more widely, leading to a potential paradigm shift in vehicle technology.”

Learning rate

To reach that level, costs will have to fall further. But a commercial breakthrough for the next generation of lithium batteries “is still distant”, the paper says, and many improvements in cell chemistry have already been realised. This seems to pour cold water on frequent claims of new battery types “transforming” the electric vehicle market.

However, there are still savings to be made in manufacturing improvements, industry learning and economies of scale, which have already brought down costs in recent years. Cumulative global production and sales of electric vehicles are roughly doubling annually, the paper says.

That means the 30% cost reduction expected at Tesla Motors’ planned “Gigafactory” battery plant by 2017 represents a “trajectory close to the trends projected in this paper”. On the other hand Renault-Nissan’s plans to build battery manufacturing capacity for 1.5 million cars by 2016 have hit the buffers as electric car sales have trailed expectations.

There are large uncertainties in the paper’s findings. Despite being the most comprehensive review to date, it relies on “sparse data” and acknowledges that a secretive industry might avoid revealing high costs, or conversely might subsidise battery packs to gain market share.

Overall it is “possible” that economies of scale will push costs down towards $200 kilowatt-hour “in the near future even without further cell chemistry improvements”, the paper concludes. If the paper is right then electric vehicle uptake could exceed expectations. That will be a good thing for the climate – just as long as the electricity that fuels them is not from coal.

Where is the electric grid headed?

19 11 2014

Followers of this blog will know my enthusiasm for solar power as a silver bullet for our future energy predicaments has waned, and in particular, my love affair with grid tied solar is over.  I have also been doubting for quite some time that the future of the electric grid is secure, and have on occasions discussed stand alone solar power as a possibility for those of us who are aware of the coming dilemmas to stretch their energy horizon a little further and make the inevitable energy descent less painful.  Well, it seems, this theme is catching on, even making it to what I consider to be mainstream internet sources.

Recently, on the Climate Spectator website (an arm of Alan Kohler’s straight as a die Business Spectator financial website), an article titled “Solar wins! Zombie-grid a dead man walking” began with this paragraph:

The grid financial model will collapse within 10 years, as millions of Australian households flee for the new, disruptive and cheaper alternative. This change will be as big as the conversion from horse and cart to motor vehicle, film to digital camera and the typewriter to the laptop.

I nearly fell off my chair…… because let’s face it, if the collapse of the grid financial model is not soon followed by total collapse, I would eat my hat.  The reasons the author – Matthew Wright CEO of Beyond Zero Emissions – gives for this prediction are:

Modeling by Zero Emissions Australia shows that an ordinary, but all-electric, household using off-the-shelf efficient electric appliances could be off the grid for between $30,000-$40,000 today and $12,000-$20,000 in 2024.

This is based on the following representative example of electricity demand charted below for an all-electric five-person household in Melbourne.

Example: One year of average monthly demand for all electric household in Melbourne (5 occupants).

Households can install and size their off-grid solar system now and change their redundant gas appliances (stove top, gas hot water and gas heating) over later. Or, given that the price is going to be right to leave sometime in the next 10 years, they can start their electric conversion journey now. Ditching gas and the power grid starts by installing an oversized solar system (11-15kW) on the north, east, west and possibly even flat-racked. Indeed you can place it on the south face which captures diffuse light when its cloudy – which contributes over half of all generation during the middle of winter (more on that in another article).

10kW PV System

10kW PV System

I’m frankly AGHAST!  I wonder if Matthew has even ever seen a 10kW PV system (let alone a 15 kW one…)  One of my neighbours has such a large system on his roof, installed before Energex put their foot down and limited grid tied systems to 5kW, and it looks like the photo opposite.  Bear in mind this house was designed for solar to begin with, faces true North, built with a skillion roof, and is bigger than our place by some margin at 250m².  And yet, its roof is completely covered….  Try that on a standard McMansion hipped roof….

Consumption is consumption, whether it’s PVs or whatever, and at least KC exports 90% or more of what power his system produces, he doesn’t actually need it to run his house!  Any household that needs 11 to 15kW of solar has a serious efficiency problem that needs to be solved before spending “$30,000-$40,000“, and if Matthew believes such schemes are ways of dealing with Carbon emissions, he is seriously mistaken.

Then, he pushes heat pumps for water heating rather than solar……  I thought the title of this piece was “solar wins!”?  Why buy an electricity consuming gadget, even if very efficient, when there are alternatives that do not?  Matthew doesn’t even seem to understand the physics of energy with the statement “achieves Coefficient of Performance (COP) of ~4.0 or (400% efficient, yes that is possible)”  NO Matthew, 400% efficiency is NOT possible, COP is not efficiency…..  And you wonder why I have so many doubts about BZE’s green wet dream of 100% renewables for Australia?

But back to our grid problems.

“Industrialized countries face a future of increasingly severe blackouts, a new study warns, due to the proliferation of extreme weather events, the transition to unconventional fossil fuels, and fragile national grids that cannot keep up with rocketing energy demand” says Motherboard….

The paper published this September in Routledge’s Journal of Urban Technology points out that 50 major power outages have afflicted 26 countries in the last decade alone, driven by rapid population growth in concentrated urban areas and a rampant “addiction” to high-consumption lifestyles dependent on electric appliances.

Study authors Hugh Byrd and Prof Steve Matthewman of Auckland University, a sociologist of disaster risk, argue that this escalating demand is occurring precisely “as our resources become constrained due to the depletion of fossil fuel, a lack of renewable energy sources, peak oil and climate change.”

Blackouts, they warn, are “dress rehearsals for the future in which they will appear with greater frequency and severity,” they find. “We predict increasing numbers of blackouts due to growing uncertainties in supply and growing certainties in demand.”

The relentless growth in demand, 1300 percent from 1940 to 2001 in the US (and likely much the same here), is the obvious culprit with aircon requirements at the forefront.  And let’s not forget the coming new fad…..

Adding further pressure to future electricity demand is the rise of the electric vehicle, driven by efforts to mitigate climate change. Byrd and Matthewman note that in higher-income regions, switching entirely to electric cars would increase electricity demand by 15-40 percent. Even if we replaced all our petrol-guzzling cars with “highly efficient” electric cars, the new models would still consume about “twice as much electricity as residential and commercial air-conditioning combined.”

And as climate change brings warmer Summers and more intense rains to regions of North America and Australia, people resort to more and more air-conditioning to stay cool, another climate positive feedback loop maybe?

Worldwide, overall energy demand for air-conditioning “is projected to rise rapidly to 2100,” to as much as 40 times greater than it was in 2000. New York alone will need 40 percent more power in the next 15 years partly because the city will contain a million more people, aided of course by electrical appliances, elevators, and air-conditioning.

Yeah right….  like that‘s going to happen, with a failing grid model….?  The article even goes further saying “But in a slow-growth global economy hell-bent on austerity, the prospects for large government investments in grid resilience look slim. According to the global insurance company Allianz in an extensive report on blackout risks in the US and Europe, “privatization and liberalization” have contributed to “missing incentives to invest in reliable, and therefore well maintained, infrastructures.””

A new report by the French multinational technology firm CapGemini warns of a heightened risk of blackouts across Europe this winter due to the shut-down of gas-fired plants, competition from cheap US coal, and the big shift to wind and solar. Ironically, electricity surpluses from renewables have led to a fall in power prices and crippled fossil fuel utilities, which in turn has reduced the “electricity system’s margin to meet peak demand in specific conditions such as cold, dark and windless days,” according to the report.

So it seems the grid’s financial model in Europe is in just as deep a hole as Australia’s.  The more I think of the terminology ‘disruptive’ used to describe renewables, the more I think it’s accurate!  The increasing shift to renewable energy sources has, it appears, exacerbated the blackout risk not because they are bad at generating power, but because of the difficulty in integrating volatile, decentralized energy sources into old power grids designed half a century ago around the old fossil fuel model.  Something the BZE people just don’t seem to understand.

Take this for example:  Our friend Matthew Wright is at it again with “Imagine 1000 gigafactories – that’s what’s coming”

No doubt you have all heard of El on Musk, the CEO of Tesla, the electric car company.  “Tesla is everyone’s favourite motor car company, a darling of investors large and small. Rev heads who have driven a Tesla give it the nod” writes Matthew.  Well of course they’d give it the nod…. just like anyone who drives a brand new Range Rover would give that car the nod; after all, after driving our old bombs around, I’m sure I would be mighty impressed with a car worth some $70,000 too……

Musk’s gigafactories will be the world’s largest lithium-ion battery factory, and is expected to generate as much renewable energy as it needs to operate — and then some.  But is that thin line at the bottom right of the photo a road, or a mighty big cable going to Bolivia’s Lithium mines…?

Here’s the first problem with celebratory headlines over renewables: record renewable energy growth hasn’t stopped record fossil fuel burning, including record levels of coal burning. Coal use is growing so fast that the International Energy Authority expects it to surpass oil as the world’s top energy source by 2017.  And building gigafactories is only worsening the problem.

Mabe, the 1,500 gigawatts of electricity produced from renewables worldwide have prevented a further 1,500 gigawatts of fossil fuel power stations? Who can tell?  It’s just as possible that renewables have simply added 1,500 gigawatts of electricity to the global economy, fuelling economic growth and ever-greater industrial resource use. That being the case, far from limiting carbon dioxide emissions worldwide, renewables may simply have increased them because, as I’ve written many times before, no form of large-scale energy is carbon neutral.

And no one mentions the looming economic crisis having an effect on the grid’s reliability.  The future is taboo.  Watch this space…





Another Silver Bullet Jams in the Breach…….

23 08 2014

One of the silver bullets constantly used by techno Utopians is of course the Electric Car, popularly known as EVs (the V stands for vehicle).  Before the believers in this technology jump down my throat for demolishing their ideals, let me tell you I am planning – the timing of the collapse allowing of course – to eventually convert my trusty ute to electric drive once I get it safely to Tasmania.  Now you may ask why I would do that if I don’t believe in EVs taking over the world in the first place, and I’ll forgive you for asking……  but like everything else I’m about to do in the face of collapse, the motive is purely selfish.  Though I expect such a vehicle could well become a communal asset that might make me popular enough to get assistance with implementing all sorts of other ideas I have for our post crash  future.  It won’t be used for shopping or dropping kids to soccer matches, that’s for sure, but a vehicle capable of carrying a ton of firewood or compost or scrap building materials will sure come in handy.  How fast it can go, or what its range is, or what it’s nought to sixty figure is, are totally irrelevant…. the reason I’ll be doing this is to ensure we have access to a workhorse in the post oil era.

I don’t expect it will be driven that much, and it should be easily kept charged up using the renewable energy I’m planning to install at our next abode.  Let’s hope the Matrix stays together long enough to actually achieve this.

Converting an old car to electric drive means you don’t have to build a whole car.  The amount of energy and resources needed to build a car, any car (and it actually takes more resources to build an EV than an IC powered vehicle of the same size..) is truly staggering.  There was one paragraph in one of my recent posts that was very telling, and that I must resurface here in case anyone reading this has not read it yet…:

“Most of the pollution any car will ever cause is generated in the production process before the car even arrives at the showroom — in the production of all the steel, aluminium, copper and other metals, glass, rubber, plastic, paint and other raw materials and inputs that go into every automobile, and in the manufacturing process itself. Cars produce 56 percent of all the pollution they will ever produce before they ever hit the road. … [S]o long as [automakers] are free to produce automobiles without limit more cars will just mean more pollution, even if the cars are hybrids or plug-in electric cars.”

This is actually far worse than the 60 to 90 barrels of oil I’ve been quoting for years……  XRayMike, as usual, puts this into perspective in his own inimitable way:

The role that fossil fuels play in the creation, maintenance and support of alternative energy technologies is not discussed or analyzed at all by those peddling it to the masses who live with the hope of a “green” economy and carbon-neutral civilization. From the massive mining operations and manufacturing processes necessary to extract the rare earth metals essential in constructing wind turbines, solar panels, and electric car batteries to their daily maintenance, de-activation, and final discardment, the amount of fossil fuel energy embedded in the entire life cycle of such alternative energy technologies renders moot their benefits when compared to what is actually more effective in solving our energy and climate conundrum —reducing our consumption through energy efficiency improvements and waste reduction programs. Alternative energy technologies cannot replace our dependence on fossil fuels and are, in the final analysis, diverting us from coming to grips with a way-of-life that cannot go on for much longer. We have a consumption crisis.

Buried in the comments at the abovementioned page of this blog, Gordon sourced a German report that has figures showing that the pollution numbers for the manufacture of EVs are so bad, that in any event, converting to ‘green transport’ would only reduce CO2 emissions by 20%.  When in fact we need immediate reductions of at least 90%.

“Cars produce 56 percent of all the pollution they will ever produce before they ever hit the road. …”

I think the more relevant quote from the original German Environment and Forecasting Institute report is, in relation to CO2 emissions:

68% of all of a car’s emissions comes from processing and transporting the raw materials;10% is emitted as a result of manufacturing, scrapping, and constructing roads and garage facilities; and only 22% of CO2 emissions comes from the actual operation of the car. http://www.solarpolis.de/Archiv/Seiten/solarmo2.htm#Kap7Unterkap2UU1

So assuming that this distribution of emissions applies broadly to electric vehicles, a total changeover to electric cars would save only around 20% of the car-related emissions.

Now bring online the manufacturing of millions of such cars, and emissions will not drop, they will rise dramatically.

Following Elon Musk’s public release of all his Tesla patents, l can’t help but wonder if his real motivation is hidden in the penultimate paragraph of this article on The Conversation:

The latest move by Tesla and its partner, Panasonic, will see the construction of the new Gigafactory, which will produce long range battery packs for Tesla’s electric vehicles.

He is not really in the electric vehicle business at all, he is in the battery business.  I’m sure he’s smart enough to have seen the writing on the wall too….  No matter what else goes into an individual electric vehicle design, they will all need batteries.  And these batteries will better serve stationary use than mobile ones that will have to deal with fast deteriorating roads in a post crash world.

Below is an excerpt from a must-see talk by engineer and energy analyst Ozzie Zehner, author of Green Illusions:

Common knowledge presumes that we have a choice between fossil fuels and green energy, but alternative energy technologies rely on fossil fuels through every stage of their life cycle. Most importantly, alternative energy financing relies ultimately on the kind of economic growth that fossil fuels provide. Alternative energy technologies rely on fossil fuels for raw material extraction, for fabrication, for installation and maintenance, for back-up, as well as decommissioning and disposal. And at this point, there’s even a larger question: where will we get the energy to build the next generation of wind power and solar cells? Wind is renewable, but turbines are not. Alternative energy technologies rely on fossil fuels and are, in essence, a product of fossil fuels. They thrive within economic systems that are themselves reliant on fossil fuels.

Now, I’m no fan of fossil fuels. Fossil fuels are finite and dirty, but we use them for five principal reasons. Fossil fuels are dense. Their energy is storable, portable, fungible (which means they can be easily traded), and they are transformable into other products like pesticides, fertilizers, and plastics.

I have only just discovered Zehner.  Hat tip to XRayMike for introducing me to this extraordinary man…  He is basically saying the exact same thing I’ve been saying for years, only better, and he knows even more than I about how ridiculous the whole concept of running the world on solar is.  Like me, he also understands the Power of Energy Efficiency.  Even the power of a sticker…  The must see talk is here…..  it will blow you away, I guarantee it:

After seeing that, maybe I should even reconsider all my plans for Tasmania…..  like buying fifty years supply of inverters!
