‘Eat Less Meat’ Ignores the Role of Animals in the Ecosystem

27 01 2018

Lifted from Civil Eats…… it’s fortunately what we were taught at the Small Farm Planning course, and it’s mercifully slowly catching on. My neighbour’s cows are currently on my land, building soil and reducing fire danger all at the same time.

Given the concerns over resource-intensive industrial meat production, you’d think the resounding message would be, “don’t buy cheap meat, buy good meat.”

Instead, a rule of thumb that has emerged in environmentalists’ circles is simply “eat less meat.” This statement frames meat as an indulgence rather than 1) the end result of an essential and timeless ecological process (the biological breakdown of vegetation, which feeds the soil and removes dead grass so that new vegetation can grow) and 2) a fulcrum in the way land across the world is managed or mismanaged.

As a grazier and land manager, I’m part of a growing group of people who have committed our lives to restoring the health of environments directly, through exquisitely precise grazing on sensitive land, and who depend on the support of our communities to do this work.

“Eat less meat” is a well-intended caveat amongst woke environmentalists (a group who is, after all, my cohort) but it has also become a primary barrier to me and others like me doing our work. And it’s hard to not take that personally. Because what could be more personal than the health of my watershed and the kingdoms that inhabit it? If these things aren’t personal to you, we have a bigger problem.

Our work goes like this: We memorize every nook and cranny of a piece of land like a lover’s body. We study how water flows across it and what grasses grow where. We plant trees where we’ve seen them grow before and could grow again. We spend unpaid hours moving animals exactly where they need to go to knock down encroaching brush on long-neglected land. We fence out bird nests. We leave areas ungrazed for a season—and can calculate the cost to the tune of hundreds of dollars—because we know in our throats, our chests, our bellies, and our bones (that’s where we feel it) that it needs another season to grow before grazing would be helpful. We get knocked down, kicked, cut up and cut open; we don’t just risk injury but accept its inevitability. We memorize the names of species that used to grow or live here but have been lost. We love the land and its inhabitants so much that we’re willing to work for next to nothing.

But martyrdom isn’t very becoming, and you can’t milk a dry cow; so like everyone else, graziers have to make money. Until environmentalists actually really put their money where their mouth is and pay me and others to graze land right without meat as the chief goal, we have to sell the surplus from our herds (the flesh of some of the animals) in order to be able to afford to feed ourselves.

Believe me, I wish I were a photosynthesizing autotroph who could get my nourishment directly from the sun.

Not all grazing is created equal. This is the essence of what gets missed in discussions about the impact of livestock agriculture on our local ecosystems and global climate. Decades of mismanagement has left a tough legacy for those of us grazing with restorative goals to overcome. But when animals are managed according to nature’s schedule, beautiful changes can happen fast.

Some of the year I graze the animals in tight bunches to lay down old grass to feed the soil. Other times, I’m herding them fast across the property to stimulate grass plants to grow denser and healthier while they pump carbon deep into the soil food web. I can stop erosion around streams based on how I move these big animals, and stabilize vulnerable hillsides through careful decision-making. For me and many like me, grazing is our art form—it’s our best tool for breathing new life into neglected land.

“Eat less meat” is about mitigating damage, and it misses the opportunity to tell people that there’s a way to actually benefit their planet. Industrially produced meat is unquestionably bad for the environment, and for animals. But perpetuating the myth that all meat is the same means that the potential benefits of responsibly raised meat never get a sufficient foothold. By telling only half the story, we’re perpetuating the problem because we never bother to mention the solution.

 

As an aside, few environmentalists who are opposed to grazing animals and eating their flesh have demonstrated either the degree of embodied affection, personal risk, and deep practice or the knowledge of grassland dynamics, plant succession, and wildlife movement that I’ve seen among the graziers in my life. So I urge those who care about the meat industry’s impact on the environment to bring more curiosity and humility to the discussion.

When we say “eat less meat” and end it there, we miss an opportunity to equip eaters with the means of sourcing protein that will not only nourish them but restore their home ecosystems. And behind every few hundred acres of land that goes poorly managed due to consumer miseducation is a land steward who can’t do their work.

Appetite is energy. Rather than try to halt the tide of appetite for meat by discouraging its consumption outright, a better way to steward that energy would be to concentrate on where it would it can do the most good. In doing so, we’re not just improving our environment, we’re widening the demand for graziers who can produce meat and serve as ecological service providers.

So don’t “eat less meat.” Eat meat from people whose hands you can shake and whose ranches you can visit. Eat as much of that as you can afford, because that stuff comes from extensive production systems that impact hundreds and thousands of acres. Sourcing your protein from places you can account for means you can verify that their pastures are also habitat for foxes, badgers, burrowing owls, and bears—that you are keeping land wild and free. As I see it, beef raised in its environs beats a bean field any day as an ecologically just source of protein.

This type of meat isn’t cheap—and you might find that you value it differently and stop taking it for granted. The end result may very well be that far less meat is consumed overall, at least for a while. But the quantity doesn’t matter to me—what matters is what that animal did in its life on earth.

We have to pay for the world we want to live in. This means consuming the flesh of other sentient animals may damn well require a line-item on our budgets, alongside “eating out” and “entertainment.” Maybe it’s time we socialized ourselves and others to budget for environmental activism, and use that money to buy meat produced by the soil-building, grassland-loving graziers in our communities.

Everything Must Go

Economic growth will destroy everything. There’s no way of greening it – we need a new system.

By George Monbiot, published in the Guardian 22nd November 2017

 

George-Monbiot-L

George Monbiot

Everyone wants everything – how is that going to work? The promise of economic growth is that the poor can live like the rich and the rich can live like the oligarchs. But already we are bursting through the physical limits of the planet that sustains us. Climate breakdown, soil loss, the collapse of habitats and species, the sea of plastic, insectageddon: all are driven by rising consumption. The promise of private luxury for everyone cannot be met: neither the physical nor the ecological space exists.

But growth must go on: this is everywhere the political imperative. And we must adjust our tastes accordingly. In the name of autonomy and choice, marketing uses the latest findings in neuroscience to break down our defences. Those who seek to resist must, like the Simple Lifers in Brave New World, be silenced – in this case by the media. With every generation, the baseline of normalised consumption shifts. Thirty years ago, it was ridiculous to buy bottled water, where tap water is clean and abundant. Today, worldwide, we use a million plastic bottles a minute.

Every Friday is a Black Friday, every Christmas a more garish festival of destruction. Among the snow saunasportable watermelon coolers and smart phones for dogs with which we are urged to fill our lives, my #extremecivilisation prize now goes to the PancakeBot: a 3-D batter printer that allows you to eat the Mona Lisa or the Taj Mahal or your dog’s bottom every morning. In practice, it will clog up your kitchen for a week until you decide you don’t have room for it. For junk like this we’re trashing the living planet, and our own prospects of survival. Everything must go.

The ancillary promise is that, through green consumerism, we can reconcile perpetual growth with planetary survival. But a series of research papers reveal that there is no significant difference between the ecological footprints of people who care about their impacts and people who don’t. One recent article, published in the journal Environment and Behaviour, finds that those who identify themselves as conscious consumers use more energy and carbon than those who do not.

Why? Because, environmental awareness tends to be higher among wealthy people. It is not attitudes that govern our impacts on the planet, but income. The richer we are, the bigger our footprint, regardless of our good intentions. Those who see themselves as green consumers, the paper found, “mainly focus on behaviours that have relatively small benefits.”

I know people who recycle meticulously, save their plastic bags, carefully measure the water in their kettles, then take their holidays in the Caribbean, cancelling their environmental savings 100-fold. I’ve come to believe that the recycling licences their long-haul flights. It persuades people they’ve gone green, enabling them to overlook their greater impacts. [I know people like that too…]

None of this means that we should not try to reduce our impacts, but we should be aware of the limits of the exercise. Our behaviour within the system cannot change the outcomes of the system. It is the system that needs to change.

Research by Oxfam suggests that the world’s richest 1% (if your household has an income of £70,000 or more, this means you) produce around 175 times as much carbon as the poorest 10%. How, in a world in which everyone is supposed to aspire to high incomes, can we avoid turning the Earth, on which all prosperity depends, into a dust ball?

By decoupling, the economists tell us: detaching economic growth from our use of materials. So how well is this going? A paper in the journal PlosOne finds that while in some countries relative decoupling has occurred, “no country has achieved absolute decoupling during the past 50 years.” What this means is that the amount of materials and energy associated with each increment of GDP might decline, but, as growth outpaces efficiency, the total use of resources keeps rising. More importantly, the paper reveals that, in the long term, both absolute and relative decoupling from the use of essential resources is impossible, because of the physical limits of efficiency.

A global growth rate of 3% means that the size of the world economy doubles every 24 years. This is why environmental crises are accelerating at such a rate. Yet the plan is to ensure that it doubles and doubles again, and keeps doubling in perpetuity. In seeking to defend the living world from the maelstrom of destruction, we might believe we are fighting corporations and governments and the general foolishness of humankind. But they are all proxies for the real issue: perpetual growth on a planet that is not growing.

Those who justify this system insist that economic growth is essential for the relief of poverty. But a paper in the World Economic Review finds that the poorest 60% of the world’s people receive only 5% of the additional income generated by rising GDP. As a result, $111 of growth is required for every $1 reduction in poverty. This is why, on current trends, it would take 200 years to ensure that everyone receives $5 a day. By this point, average per capita income will have reached $1m a year, and the economy will be 175 times bigger than it is today. This is not a formula for poverty relief. It is a formula for the destruction of everything and everyone.

When you hear that something makes economic sense, this means it makes the opposite of common sense. Those sensible men and women who run the world’s treasuries and central banks, who see an indefinite rise in consumption as normal and necessary, are beserkers, smashing through the wonders of the living world, destroying the prosperity of future generations to sustain a set of figures that bear ever less relation to general welfare.

Green consumerism, material decoupling, sustainable growth: all are illusions, designed to justify an economic model that is driving us to catastrophe. The current system, based on private luxury and public squalor, will immiserate us all: under this model, luxury and deprivation are one beast with two heads.

We need a different system, rooted not in economic abstractions but in physical realities, that establish the parameters by which we judge its health. We need to build a world in which growth is unnecessary, a world of private sufficiency and public luxury. And we must do it before catastrophe forces our hand.

The beginning of the end for the USA?

America Can’t Afford to Rebuild

By Raul Illargi

A number of people have argued over the past few days that Hurricane Harvey will NOT boost the US housing market. As if any such argument would or should be required. Hurricane Irma will not provide any such boost either. News about the ‘resurrection’ of New Orleans post-Katrina has pretty much dried up, but we know scores of people there never returned, in most cases because they couldn’t afford to.

And Katrina took place 12 years ago, well before the financial crisis. How do you think this will play out today? Houston is a rich city, but that doesn’t mean it’s full of rich people only. Most homeowners in the city and its surroundings have no flood insurance; they can’t afford it. But they still lost everything. So how will they rebuild?

Sure, the US has a National Flood Insurance Program, but who’s covered by it? Besides, the Program was already $24 billion in debt by 2014 largely due to hurricanes Katrina and Sandy. With total costs of Harvey estimated at $200 billion or more, and Irma threating to cause far more damage than that, where’s the money going to come from?

It took an actual fight just to push the first few billion dollars in emergency aid for Houston through Congress, with four Texan representatives voting against of all people. Who then will vote for half a trillion or so in aid? And even if they do, where would it come from?

 

 

Trump’s plans for an infrastructure fund were never going to be an easy sell in Washington, and every single penny he might have gotten for it would now have to go towards repairing existing roads and bridges, not updating them -necessary as that may be-, let alone new construction.

Towns, cities, states, they’re all maxed out as things are, with hugely underfunded pension obligations and crumbling infrastructure of their own. They’re going to come calling on the feds, but Washington is hitting its debt ceiling. All the numbers are stacked against any serious efforts at rebuilding whatever Harvey and Irma have blown to pieces or drowned.

As for individual Americans, two-thirds of them don’t have enough money to pay for a $500 emergency, let alone to rebuild a home. Most will have a very hard time lending from banks as well, because A) they’re already neck-deep in debt, and B) because the banks will get whacked too by Harvey and Irma. For one thing, people won’t pay the mortgage on a home they can’t afford to repair. Companies will go under. You get the picture.

There are thousands of graphs that tell the story of how American debt, government, financial and non-financial, household, has gutted the country. Let’s stick with some recent ones provided by Lance Roberts. Here’s how Americans have maintained the illusion of their standard of living. Lance’s comment:

This is why during the 80’s and 90’s, as the ease of credit permeated its way through the system, the standard of living seemingly rose in America even while economic growth rate slowed along with incomes. Therefore, as the gap between the “desired” living standard and disposable income expanded it led to a decrease in the personal savings rates and increase in leverage. It is a simple function of math. But the following chart shows why this has likely come to the inevitable conclusion, and why tax cuts and reforms are unlikely to spur higher rates of economic growth.

 

 

There’s no meat left on that bone. There isn’t even a bone left. There’s only a debt-ridden mirage of a bone. If you’re looking to define the country in bumper-sticker terms, that’s it. A debt-ridden mirage. Which can only wait until it’s relieved of its suffering. Irma may well do that. A second graph shows the relentless and pitiless consequences of building your society, your lives, your nation, on debt.

 

 

It may not look all that dramatic, but look again. Those are long-term trendlines, and they can’t just simply be reversed. And as debt grows, the economy deteriorates. It’s a double trendline, it’s as self-reinforcing as the way a hurricane forms.

 

Back to Harvey and Irma. Even with so many people uninsured, the insurance industry will still take a major hit on what actually is insured. The re-insurance field, Munich RE, Swiss RE et al, is also in deep trouble. Expect premiums to go through the ceiling. As your roof blows off.

We can go on listing all the reasons why, but fact is America is in no position to rebuild. Which is a direct consequence of the fact that the entire nation has been built on credit for decades now. Which in turn makes it extremely vulnerable and fragile. Please do understand that mechanism. Every single inch of the country is in debt. America has been able to build on debt, but it can’t rebuild on it too, precisely because of that.

There is no resilience and no redundancy left, there is no way to shift sufficient funds from one place to the other (the funds don’t exist). And the grand credit experiment is on its last legs, even with ultra low rates. Washington either can’t or won’t -depending on what affiliation representatives have- add another trillion+ dollars to its tally, state capitals are already reeling from their debt levels, and individuals, since they have much less access to creative accounting than politicians, can just forget about it all.

Not that all of this is necessarily bad: why would people be encouraged to build or buy homes in flood- and hurricane prone areas in the first place? Why is that government policy? Why is it accepted? Yes, developers and banks love it, because it makes them a quick buck, and then some, and the Fed loves it because it keeps adding to the money supply, but it has turned America into a de facto debt colony.

If you want to know what will happen to Houston and whatever part of Florida gets hit worst, think New Orleans/Katrina, but squared or cubed -thanks to the 2007/8 crisis.





How an obscure Austrian philosopher saw through our empty rhetoric about ‘sustainability’

5 07 2017

Hot Mess

Marc Hudson, University of Manchester

“Sustainability” is, ironically, a growth industry. Ever since the term “sustainable development” burst onto the scene in 1987 with the release of Our Common Future (also known as the Brundtland report), there has been a dizzying increase in rhetoric about humanity’s relationship with our planet’s resources. Glossy reports – often featuring blonde children in front of solar panels or wind turbines – abound, and are slapped down on desks as proof of responsibility and stewardship.

Every few years a new term is thrown into the mix – usually preceded by adjectives like “participatory” or “community-led”. The fashionability of “resilience” as a mot du jour seems to have peaked, while more recently the “circular economy” has become the trendy term to put on grant applications, conference notices and journal special editions. Over time journals are established, careers are built, and library shelves groan.

Meanwhile, the planetary “overshoot”, to borrow the title of a terrifying 1980 book, goes on – exemplified by rising concentrations of atmospheric carbon dioxide, warmer oceans, Arctic melting, and other signs of the times.

With all this ink being spilled (or, more sustainably, electrons being pressed into service), is there anything new to say about sustainability? My colleagues and I think so.

Three of us (lead author Ulrike Ehgartner,
second author Patrick Gould
and myself) recently published an article called “On the obsolescence of human beings in sustainable development”.

In it we explore the big questions of sustainability, drawing on some of the work of an unjustly obscure Austrian political philosopher called Gunther Anders.

Who was Günther Anders?

He was born Günther Siegmund Stern in 1902. While he was working as a journalist in Berlin, an editor wanted to reduce the number of Jewish-sounding bylines. Stern plumped for “Anders” (meaning “other” or “different”) and used that nom de plume for the rest of his life.

Anders knew lots of the big philosophical names of the day. He studied under Edmund Husserl and Martin Heidegger. He was briefly married to Hannah Arendt, and Walter Benjamin was a cousin.

But despite his stellar list of friends and family, Anders himself was not well known. Harold Marcuse points out that the name “Stern” was pretty apt, writing:

His unsparingly critical pessimism may explain why his pathbreaking works have seldom sparked sustained public discussion.

While Hiroshima and the nuclear threat were the most obvious influences on Anders’ writing, he was also crucially influenced by the events at Auschwitz, the Vietnam War, and his periods in exile in France and the United States. But why should we care, and how can his ideas be applied to modern-day ideas about sustainability?

Space precludes a blow-by-blow account of what my colleagues and I wrote, but two ideas are worth exploring: the “Promethean gap” and “apocalyptic blindness”.

Anders suggested that the societal changes wrought by the industrial age – chief among them the division of labour – opened a gap between individuals’ capability to produce machines, and their capability to imagine and deal with the consequences.

So, riffing on the Greek myth of Prometheus (the chap who stole fire from Mount Olympus and gave it to humans), Anders proposed the existence of a “Promethean gap” which manifests in academic and scientific thinking and leads to the extensive trivialisation of societal issues.

The second idea is that of “apocalyptic blindness” – which is, according to Anders, the mindset of humans in the Age of the Third Industrial Revolution. This, as we write in our paper:

…determines a notion of time and future that renders human beings incapable of facing the possibility of a bad end to their history. The belief in progress, persistently ingrained since the Industrial Revolution, causes the incapability of humans to understand that their existence is threatened, and that this could lead to the end of their history.

Put simply, we don’t want to look an apocalypse in the eye, even if it’s heading straight towards us.

The climate connection

“So what?” you might ask. Why listen to yet another obscure philosopher railing about technology, in the vein of Lewis Mumford and Jacques Ellul? But I think a passing knowledge of Anders and his work reminds us of several important things.

This is nothing new. Recently, the very notion of ‘progress’ has come under renewed assault, with books questioning our assumptions about it. This is not new of course – in a 1967 short story collection about life at the United Nations, Shirley Hazzard had written:

About this development process there appeared to be no half-measures: once a country had admitted its backwardness, it could hope for no quarter in the matter of improvement. It could not accept a box of pills without accepting, in principle, an atomic reactor. Progress was a draught that must be drained to the last bitter drop.

The time – if ever there was one – for tinkering around the edges is over. We need to take stronger action than simply pursuing our feelgood preoccupation with sustainability.

This begs the question of who is supposed to shift us from the current course (or rather, multiple collision courses. That’s a difficult one to answer.

The hope that techno-fixes (including 100% renewable energy) will sort out our problems is a dangerous delusion (please note, I’m not against 100% renewables – I’m just saying that green energy is “necessary but not sufficient” for repairing the planet).

Similarly, the “circular economy” has a rather circular feeling to it – in the sense that we’ve seen all this before. It seems (to me anyway) to be the last gasp of the “ecological modernist” belief that with a bit more efficiency, everything can simply keep on progressing.

The ConversationOur problems go far deeper. We are going to need a rapid and fundamental shift in our values, habits, behaviours, and outlooks. Put in Anders’ terms, we need to stop being blind to the possibility of apocalypse. But then again, people have been saying that for a century or more.

Not happy, Jan…….

8 04 2017

If you’ve been following this blog, you will know I’ve been saying for quite some time that out of the ludicrous Lithium battery rush happening right now as a ‘fix it’ for all and sundry energy problems, a lot of disappointed people will surface. Well, one just has, and he’s one of the most high profile person in the sustainability movement.

I met Michael Mobbs almost certainly before 2010, which is the year I went working for the solar industry. He gave a public lecture about sustainability in Pomona at the Rural Futures Network; I wonder how that’s going now..? Mobbs has undertaken converting an old terrace house in Sydney to ‘sustainability’ by disconnecting from the water grid and sewerage. He also went grid tied solar, the whole project is well documented on his website, and you have to give him credit for doing the almost impossible…. in Sydney no less. I for one would never undertake such a project, it’s so much easier to start from scratch in the country! And that’s hard enough, let me tell you….

It now appears, Mobbs decided to also cut himself off from the electricity grid…. and it seems that didn’t go so well….

mobbsbatteriesOn Mobbs’ website, there is an “invitation to install & supply an off-grid solar system” It seems he had one installed in March 2015, but it’s not working as it should, or at least as Mobbs thought it should…..

Firstly, let’s start with what he got……. It’s a bit hard to tell from the photo, apart from the fact it is an Alpha ‘box’. From the blog, I also established that this comes with a 3kW inverter, itself a problem, it appears to be too small. Going to Alpha’s website, I cannot find the system Mobbs appears so proud of in the above photo; and let’s face it, two years is a long time in the world of technology. All the products on display say that the output of these cabinets is 5kW, but nowhere does it say it even features an inverter.  Solarchoice’s website shows a 3kW Storion-S3 cabinet, but not even it looks like what Mobbs has in the photo – it only has one door, the ‘new ones’ have two….. The inverter is called an AEV-3048, and perhaps the A stands for Alpha, and 3048 means 3000W/48V, but it’s all guesswork because finding information is a problem.

So why is a 3kW inverter a problem in a house with a claimed baseload of 86W, very close to what we achieved in Cooran actually…..

Another huge flaw with the Alpha system that I’ve recently become aware of also stems from the fact that all the energy first goes through the batteries: the Alpha system’s output is always limited to 3,000W regardless of the solar size; it can’t deliver above this. This is an extremely important point to understand because it affects the way I live and how I’m able to use my appliances. I’ll break it down in a way that’s practical and simple; prepare yourself to be blown away by this outrageous system limitation.

We’ve already established that the base load of my house is 86W. Let’s say I wake up in the morning, turn on a couple of lights in the kitchen because it’s still dark (20W), turn on the toaster because I’m in the mood for toast with butter for breakfast (1,200W), and my daughter (who happens to be staying with me) turns on her hair dryer while getting ready (1,500W) and she decides she needs to put on a load of laundry before she leaves the house (500W). Doesn’t seem too out of the ordinary, right? Well, we would be in trouble: all of the power would cut off, and the Alpha system would shut down because we would have exceeded its 3,000W limit. Regardless of the size of my solar system, I can NEVER exceed 3,000W of power consumption in my house while using the Alpha system. This was very hard to swallow.

Oh Michael…….  welcome to living off the grid!

Mobbs gives a brief description of how he worked out this baseload….

Step one, determining my total base load, wasn’t as easy as I expected, especially given the fact that I have three different monitoring systems that could provide me with the information. The Efergy and Wattwatchers systems confirmed what I already knew: my house’s base load was about 86W (60W for the aerator and roughly 20W for the fridge occasionally turning on).However, where I ran into problems was with the Alpha ESS reporting system: it was saying my base load was 257W, which is three times larger than the base load reported for the house.At first I thought this difference of 171W was the base load of the Alpha system itself, but their numbers just didn’t add up.

I do have a theory here, he may have got the sums wrong because he used to be grid tied, and maybe, just maybe, his figures did not include what was exported. But I’m only guessing. My main reason for thinking this is that he is running a conventional fridge, while we achieved our low baseload using a freedge which consumes 20% of the energy a conventional fridge does…. make no mistake, a conventional fridge’s ‘baseload’ is half or more of his 86W. He’s claiming 20W for his fridge (480Wh/day, 20W x 24 hrs), but I have never seen any fridge perform that well…. Most fridges today still consume a whole kilowatthour a day. So there could be another error there.

But it gets worse……

Now you see why I said that I probably made a huge mistake by purchasing the Alpha system when going off-grid. The simple truth is that the Alpha system is not designed to be used in an off-grid setting, and they have not implemented the necessary retrofits to make it work in that environment. However, during my recent research, I came across a product that is designed specifically to be used off-grid and shows great promise for high efficiency and effective energy management: the SMA Sunny Island system.

Bad news Michael……  the SMA Sunny Island is not designed for off the grid either, it’s made to work with other SMA grid tied units in a hybrid grid/backup batteries system.

Worse still, he also seems to have storage issues….

For the last few weeks, in the particularly cloudy and rainy weather Sydney has had to endure, Mobbs had to turn off his fridge (bloody fridges, they are a curse…) during the day to ensure that the house, which he shares with two others, has enough power for a “civilised life” at night-time. Worse than that, the system has a bug in it that causes it to trip out every couple of days. It seems flashing digital lights have become part of his life….!

“I’m running short of power,” Mobbs said complaining that the system that he has in place is delivering 1kWh/day less than he expected. “I thought this would be a walk in the park, but I appear to have tripped over.”

I’m seriously starting to think a lot of installers have no idea what they are doing. I recently related the story of my friend Bruce whose inlaws replaced a perfectly good system (because of a fridge no less!), and they were sold a Sunny Island, with I was told over the phone just two days ago, gel cells for storage……… completely not what either Bruce or I would have bought. Solar companies (including this well known one who shall remain nameless) have simply turned into salespeople selling whatever it is they have in stock off catalogues…….

Mobbs then writes……

The main difference between the Alpha and Sunny Island system: Sunny Island can send solar energy directly to the house when it is needed and completely bypasses the system’s batteries. SMA’s Sunny Island system not only extends battery life by not cycling all loads through them, but using solar directly into loads means items can be set to run on timers during the day, (washing, dishwasher etc) to maximise the benefit of an abundant afternoon supply of solar. It also has a larger peak design capacity than Alpha. For example, if you have a 4kW solar system, with the SMA units that would allow a potential delivery of 4kW of solar (in optimum conditions) directly into the house’s load + the 4.6kW of power from the batteries delivered by the Sunny Island controller (they can run in parallel to each other).  That’s a big potential 8.6 kW of continuous capacity to loads.  As I’ve already pointed out, in contrast the Alpha output is always limited to the 3,000W delivery of the battery inverter regardless of the solar size.

More bad news Michael…… this only works that way if you are grid tied with a hybrid system!

Michael also doesn’t seem to understand how off the grid works…

Alpha has an inefficient way of managing my solar energy (by diverting all of it through my batteries first), which decreases my battery life by constantly charging and discharging them…

Errr…..  Michael, that’s how battery storage works! Which is of course exactly why Lithium batteries are not good at this. Mobbs also wrote…:

Like any system that transfers and converts energy from one form to another, there are going to be losses. No system is perfect. However, as I started doing more research, I became aware of a key element of the way the Alpha system operates that may mean my decision to purchase it was a huge mistake: the Alpha system transfers all its incoming solar energy through the batteries before it delivers it to the house. When I learned this, I was devastated. One of the most important figures of merit in a system such as mine are the battery losses. If you put 1kWh into a battery it doesn’t all come out! There are losses associated with both charging and discharging. The higher the charge/discharge rate, the greater proportion of energy is lost and the shorter my battery life becomes. So, I repeat, all my energy is getting charged and discharged through the batteries before I ever even see it in the house. For someone living off-grid, this level of energy loss and battery depreciation is unacceptable, and I was never made aware of it by the installer.

This is why I know there will be a lot of disappointed grid disconnectors. They have swallowed the idea that living off grid is just like living on it hook line and sinker, when it cannot possibly be. How long have I been saying solar has shortcomings?

If you’re going to go off the grid, first, you need to know exactly how much energy you’re consuming. Then you need to know what your peak power demand will be so you can size your inverter. Then, you must size your battery bank so that you can go on living through a series of cloudy days without your batteries falling over. Accurate climate data is really important. And if you ask me, any off the grid system should be tailor made for the household, not all fitted in a box…..

The comments on Mobbs’ blog are interesting, including one from Alpha who obviously can do without the bad publicity and are suggesting entering into consultation….. well if you ask me, the time for consultation is before installation, not after it’s established the gear does not perform as needed….

Furthermore, and this is most important, get batteries that can be flattened and recharged for as many times as you like, almost forever if you go the way of Nickel Iron batteries……

At least Mobbs is aware of what his system is doing, but most consumers don’t. They will buy these cabinets, not understand what the monitors tell them, and the Lithium batteries will be cycled to death, failing early without a doubt, driving incompetent solar companies broke and giving solar power a really bad name. Plus, let’s face it, by the time all these systems die, you won’t be able to get replacement bits in a post collapse world….

There is one more issue…… on his blog Mobbs shows..:

In 1996, I installed 18 solar panels, each with 120-watt capacity. It reduced the amount the house took from the grid by more than 60%. Since then, I have installed 12 additional panels, bringing my home’s total system capacity to just over 3.5kW. mobbs panels

In addition to the roof solar cells, the house uses sunlight to heat water through a standard solar hot-water system. The environmental savings achievable by using solar hot-water heaters are summed up by Gavin Gilchrist in his book, The Big Switch:
“If all the electric water heaters in Australia were replaced with solar ones, greenhouse gas emissions from Australia’s households would be cut by one-fifth.” One fifth is one mighty big saving!

The Bottom Line… I am saving hundreds of dollars every year not paying electricity bills by powering my household appliances using the Sun. 

I totally concur re the solar water heaters. Amazingly, I have friends in Geeveston who have one, and they hardly ever boost, which is astonishing considering how everyone was telling me how poorly solar would work in Tassie.

BUT…… all those original PVs were replaced when Mobbs cut the cord and increased his array size from 2kW to 5kW…… they were only ten years old, and as Prieto pointed out recently, the early retirement/replacement of PVs and balance of system can drive the ERoEI of solar to negative territory….. I can’t find mention of what happened to the obsolete 120W panels for which it might be hard to find compatible equipment.

One last thing……  his baseload of 86W is clearly wrong if a 3.5kW array can’t drive it. Our electricity habit was run for years on just 1.28kW, and I intend to now do it in Tassie with just 2kW. I rest my case.





Making America great again, and other bullshit……

21 01 2017

nafeezIt appears Nafeez Mosaddeq Ahmed has been making lots of waves lately…. The New York Observer has just run his warning of the probability of a converging oil, food and financial crash in or shortly after 2018 which I discussed here on DTM a few days ago. Not only that, it went viral, hitting the top 20 stories on Medium for several days (at one point hitting number one), and giving him ‘Top Writer’ status on ‘energy’ and ‘climate change’ there….. is the word finally getting out…..?

It gets better….. Nafeez then wrote this via Insurge intelligence in solidarity with the arising people’s movement in the form of the worldwide women’s marches, tying together how the Trumpian inauguration represents at once the culmination of a global war on women, while simultaneously starting a war on the planet.

Nafeez thinks “there is a deep, fundamental but little-understood connection between white supremacist patriarchy and misogyny, and the interlinked environment-economic crisis.” This piece is perhaps the most important – because it highlights the real symbolic meaning of the women’s marches: a planetary declaration of intent to build bridges, not walls.

Then yesterday, Nafeez  wrote another piece for VICE anticipating the Great Orange Face’s ‘America First Energy Plan’, bringing together cutting edge science on why Trump’s fossil fuel madness is doomed to kill the economy.

It simply won’t work, cannot work….. It will backfire. Big time. And it will backfire economically before it even has time to “backfire planetarily” as he so well puts it…… We are already hearing a lot of outrage, rightly so, about the cleansing of the Wipe House website of climate information, and the promotion of this madcap anti-science scheme to burn our planet to hell. We’ll hear less about the science of global net energy decline, which proves decisively that this scheme can simply never work – but you’ll find it here: 

Nafeez begins…..:

As President-elect Trump spearheads plans to boost oil, coal and gas, a major new study by one of the world’s foremost energy experts shows just how dangerous this path would be—not just for the planet, but for the economy.

The new study, just published in January as part of the SpringerBriefs in Energy series, suggests that as long we remain dependent on fossil fuels, economic contraction is inevitable. And while renewable energy offers the only potentially viable future, it is also unlikely to sustain the sort of mass consumerism we are accustomed to—like three or more cars per household, SUVS or massive military projects like aircraft carriers.

The bottom line is that we can’t sustain our present rate of consumption no matter what energy source we rely on. And clinging to oil, gas and coal in the hopes of keeping the endless growth machine alive will be even worse: leading to a spiral of debt and economic recession that has already begun.

Nafeez then introduces his readers to the concept of thermodynamics….. yes, really…!

It all comes down to physics: the laws of thermodynamics. Economies need energy to function. And to grow, they need extra energy to fuel that growth in production and consumption. But as more energy is required just to extract new energy from fossil fuels, there is less “energy surplus” available to continue driving economic growth—to ramp up even more production and consumption. And increasingly, more and more energy is being used just to maintain the existing infrastructure of society as it is, leaving less room for further growth.

“Of perhaps greater concern than the quantity of oil and other energy sources is their declining EROI [energy return on investment]”, writes study author Charles Hall, ESF Foundation Distinguished Professor of Environment Science at the State University of New York. Hall is the founder of the concept of EROI.

Hall’s ground-breaking methodology is now used by scientists around the world to measure the total value of energy a resource can generate. It works by comparing the quantity of energy extracted to the quantity of energy inputted to enable the extraction.

He points out that throughout the energy literature “there is widespread concern that net energy returns (e.g. EROI) for oil and gas are declining and likely to continue declining.” This has economic implications:

We (as in DTM followers) all knew that of course, but it’s interesting that this stuff is actually starting to go viral…..

wheredidgrowthgo

Yes indeed, where did all the growth go…… down the Limits to Growth plughole, that’s where…..

Charlie Hall’s study, Energy Return on Investment: A Unifying Principle for Biology, Economics halleroeibookand Sustainability, clearly shows a correlation between the declining abundance of resources, “as reflected in lower production and EROI for oil and other important fuels”, and the decline of economic growth.

And that gets to the crux of the problem. We need more energy to get more stuff to grow the economy. So what happens when we can’t get as much energy as before? Growth slows.

That’s why Hall fingers the declining EROI of fossil fuels as the key culprit in decreasing rates of production, which in turn has played a key role in the economic slowdown: “Past investments— over the past century— were made at a time when the production of high quality fossil fuels was increasing at rates as high as 5% a year. At the time of this writing they have declined to no more than 1% a year, and the US (and global) economies show similar pattern.”

Hall argues that modern developed economies, with their enormous infrastructures, roads and cities, are rapidly approaching “a stage where all of the available energy is used in ‘maintenance metabolism’ to support the infrastructure that exists.” This leaves less and less energy “available for net growth.”

As I have been saying for a very long time now, the 20th Century was built one brick at a time, as and when it was required, using very cheap and very dense fossil fuels with very high ERoEI. Now we have to replace all the old stuff, more or less all at once (it is getting old now…), and simultaneously build all the new stuff, with low ERoEI energy that is literally costing the Earth.

Make no mistake, America will never be great again………. Trump or no Trump.





No fracking, drilling or digging: it’s the only way to save life on Earth

29 09 2016

“Do they understand what they have signed? Plainly they do not. Governments such as ours, now ratifying the Paris agreement on climate change, haven’t the faintest idea what it means – either that or they have no intention of honoring it” writes George Monbiot in the Guardian…… but does George himself ‘get’ what he’s writing….?

Any regular visitor to this blog will know I entirely agree with the title of Monbiot’s thesis. But at least, I know it also means the end of civilisation as we know it.

Using the industry’s own figures, it shows that burning the oil, gas and coal in the fields and mines that is already either in production or being developed, is likely to take the global temperature rise beyond 2C. And even if all coal mining were to be shut down today, the oil and gas lined up so far would take it past 1.5C. The notion that we can open any new reserves, whether by fracking for gas, drilling for oil or digging for coal, without scuppering the Paris commitments is simply untenable.

Too right. Especially as we have pretty well already reached the 1.5°C threshold according to several sources.

on-the-edge-of-1-5-c

The only means of reconciling governments’ climate change commitments with the opening of new coal mines, oilfields and fracking sites is carbon capture and storage: extracting carbon dioxide from the exhaust gases of power stations and burying it in geological strata. But despite vast efforts to demonstrate the technology, it has not been proved at scale, and appears to be going nowhere. Our energy policies rely on vapourware.

All this nonsense is a substitute for a simple proposition: stop digging. There is only one form of carbon capture and storage that is scientifically proven, and which can be deployed immediately: leaving fossil fuels in the ground.

So far so good…..

[governments’] choices are as follows. First: a gradual, managed decline of existing production and its replacement with renewable energy and low-carbon infrastructure, which offer great potential for employment. Second: allowing fossil fuel production to continue at current rates for a while longer, followed by a sudden and severe termination of the sector, with dire consequences for both jobs and economies. Third: continuing to produce fossil fuels as we do today, followed by climate breakdown. Why is this a hard choice to make?

But George…… if we are at 1.5°C already, not even choice 1 is viable….

arcticspiral

The Arctic ice death spiral has lost no momentum, with current volumes at the lowest they have ever been recorded, and cruise ships actually being sent to the North West Passage for the filthy rich to see the product of their handy work……

Only an economic collapse can fix this ongoing insanity. At least it’s interesting to see Monbiot making no mention of nuclear power in this Guardian article. Has he changed his mind, or was it a mere omission..?
