Renewable Energy cannot sustain a Consumer Society

Continuing my series re-posting archive posts from my old permaculture/peak oil blog Zone5, which has now gone to the Great Blogosphere in the Sky….

The Peak Oil movement has done some good things: it has made us aware of how dependent upon fossil fuels we are, how many energy slaves we have working for us day and night; and how absurd it is therefore to claim that it is crazy to be using them, or that there is a simple alternative. Not.

Well the first two are true- Peak Oil really did do that for me, leading to me learn a great deal about energy of all sorts and think about energy in our daily lives very carefully. But in general, peak-oilers, power-downers and Transitioners shirk the logical conclusion that, as the old song goes, we “might as well face it- we’re addicted to oil” – and that that is not a bad place to be; instead, they either indulge in collapse-porn or fuel the deluded idea that wind and solar, combined perhaps with a return to Medieval peasant lifestyles, could realistically replace our immoral high-energy lifestyles.

Some in the peak oil/climate change movement were not so sanguine about what wind and solar could achieve however. The first book I ever read on the problems of trying to come off oil, years before I had ever heard the phrase “peak oil” was The Last Hours of Ancient Sunlight by Thomm Hartmann.
At the end of the book he explains how modern wind turbines and pv solar cells are themselves entirely dependent on cheap fossil fuels -not to mention a complex globalized industrial base- to manufacture them.
Another writer firmly in the “civilisation-is-bad-and- we- should-return to simpler-lifestyles” camp but who could see through the myth of replacing fossil fuels with wind and solar power is Ted Trainer. Below is a review of his book on the subject which formed one of my earliest Zone5 posts.

My views on the false claims made for renewables are one of the things that have not changed since those days. They have become more informed: in particular, I would refer to Colin McInnes’ analysis showing the importance of energy density: fossil fuels and nuclear power are two- or three orders of magnitude more energy dense than diffuse and unreliable wind and solar power.
If we look at the world leader in transition to renewables- Germany with its Energiewende- we can see even from a recent favorable report how this translates into real practical obstacles: firstly, to reach 100% renewables (including biomass and storage of surplus power as gas through electrolysis and methanation- an as yet hardly developed technology) is predicated on a 50% reduction in total energy consumption- almost as unrealistic as Trainer’s views;
and apart from anything else, includes covering fully half of Germany’s entire arable land in solar cells. An interesting thought experiment perhaps, but hardly practical.

Where I differ with Trainer today of course is a)his assumption that such a powerdown scenario is necessary or desirable; and
b) his views on “peak uranium” should nuclear power be pursued: predictions of “peak” are nearly always wrong because they underestimate the development of new technology, for new resource discoveries, new extraction technologies, and new efficiencies in end-use: fast-breeder reactors which are in the pipe-line are able to extract more than 90% of the energy from uranium fuel rods, as opposed to just 1-2% from current models. And after Uranium of course, there is Thorium.

I would also be strongly critical of his advocacy of “the Simpler Way”. There is no way to objectively differentiate “needs” from “wants”, and attempts to lay down the law and tell everyone else what constitutes “enough” seem paternalistic and oppressive. They are also based on deeply flawed Limits to Growth thinking, creating a sort of scarcity-consciousness which I feel all too often leads to a self-serving romanticizing of poverty. I also completely reject his idea that technology s not key- it is not the only crucial element, but for the billions of urban dwellers to have good lives into the future will certainly need ongoing technological innovation, as will farming and food production.

The moral approach to addressing poverty and inequality will certainly involve more energy consumption, not less.

Book Review: Ted Trainer – Renewable Energy Cannot Sustain a Consumer Society

Ted Trainer, of the University of New South Wales, has made a valuable contribution to the literature of energy and resource depletion with his new book Renewable Energy Cannot Sustain a Consumer Society.
The title says a lot I think. With the focus of most mainstream debate on peak oil and energy being on the supply side- the oil is running low so what are we going to use instead?- Trainer brings a refreshing approach in which he provides a detailed and technically comprehensive analyses of existing renewable energy options- including wind, solar thermal, solar electric, biomass and energy crops, and hydrogen, as well as a look at nuclear and the issue of storing energy- and concludes:
“…we could easily have an extremely low per capita rate of energy consumption, and footprint, based on local resources- but only if we undertake vast and radical change in economic, political, geographical and cultural systems.”

Green for Me Talk for UCC Enviro Soc

I had an enjoyable evening at the Green for Me event at UCC Environmental Society on Tuesday where I gave a talk along with Dan Boyle of the Green Party and well-known biologist and TV/radio presenter Eanna ni Lamhna as part of their Green Week.

The theme given us for our talks was “My Reasons for Being Green.”

Eanna spoke first, but I had already got into a discussion with her about population as soon as she came into the lecture hall, pointing out that birth rates are declining everywhere, and hurriedly added in a few graphs to prove my point; her own graph was I felt somewhat misleading in that it showed only the dramatic population expansion of the past hundred years, without any context or explanation that this phase finished some 20 years ago.

Update: As Patrick Hayes writes here in response to David Attenborough’s recent Malthusian remarks, even sub-Saharan Africa has seen a massive drop in birthrates:

But as Slate has observed, it’s not just the most developed nations: ‘From 1960 to 2009, Mexico’s fertility rate tumbled from 7.3 live births per woman to 2.4, India’s dropped from six to 2.5, and Brazil’s fell from 6.15 to 1.9. Even in sub-Saharan Africa, where the average birthrate remains a relatively blistering 4.66, fertility is projected to fall below replacement level by the 2070s.’

All of which is bad news for Attenborough and his Malthusian ilk, as it reveals that what lurks behind their doom-mongering is prejudice rather than fact. That becomes increasingly evident when you hear headline-generating comments, such as those Attenborough made recently to the Radio Times: ‘We keep putting on programmes about famine in Ethiopia; that’s what’s happening. Too many people there. They can’t support themselves – and it’s not an inhuman thing to say. It’s the case.’

Too many people in Ethiopia? This is a country which, according to the World Bank, has a mere 83 people per square kilometre. This is the same as Serbia, and there aren’t mass starvations there. At 196 people per square kilometre, Switzerland has a far higher population density than Ethopia, but people aren’t starving there. Nor in Japan, where there are 350 people per square kilometre, or the Netherlands, which has 493 people per square kilometre.

She then went on to talk about climate change and supported the issues around this with two more rather misleading slides, one of polar bears and one of deserts. Polar bears are of course the poster child of climate change and have been used to very good propaganda effects since before Al Gore; but the reality seems very different- many polar bear populations are increasing, they seem remarkably adaptable to declining sea ice.
A much greater threat to bears in the Arctic than global warming is hunting.

So bears polar bears are probably an eye-catching but bad example of the effects of climate change- so far at least. Similarly, desertification also is more complex than just laying it at the feet of CO2 emissions- de-forestsation from human activity being another obvious cause, with underlying poverty often being the problem.

Eanna then wnet onto talk about renewable energy- “we have very little renewable energy- and yet the wind blows all the time!” Yes, it’s a no-brainer: humans, especially Irish humans in a country that has been hailed as the Saudi Arabia of wind- choose to use Polar-Bear murdering fossil fuels when they could just switch to clean wind.

Unfortunately, one of the major draw-backs with wind is that it does not in fact blow all the time even in Ireland, as anyone who has lived off-grid with wind-power as I have done in the past will tell you: plenty of calm still “soft” days Ireland where you get effectively no power from wind, no matter how many turbines you might have.

Even a super-grid covering the whole of Europe would not solve the problem– there is really quite dramatic indetermittency issues Europe-wide as well. For this reason, wind can never on its own replace fossil fuels or nuclear, and as another graph of Eanna’s showed quite well, renewables currently only supply a tiny percentage of energy- for well-understood reasons that are more to do with the laws of physics and cost than anything else.

More controversially, Eanna then went onto discuss waste, asking why dont we have have incinerators- a local hot-potato. “You can’t even mention them- they are considered as bad as GMOs!” The last time I had seen Eanna was at the potato day last year in Skibbereen, where she had had done an admirable job of myth-busting about the GE potato trials that started last year.

She then commented that at the protest meetings on incinerators she had been to, at the break about a third of the protestors went out to smoke!

Eanna finished her entertaining talk by admonishing us to eat only food that is in season and plant trees to help combat climate change.

I was up next, and began by staking out my credentials as a back-to-the-lander. While preparing the presentation I had in fact dug up photos of a commune I had lived in in the 1980s on the Welsh borders.

This is a photo of the Earthworm Housing Co-op from 1990, possibly when I was still actually living there.Brings back memories- many of which make me cringe!


I then discussed my involvement with the Peak Oil movement, and how my views had changed as time went on and the expected collapse failed to materialise, and the new energy story became one of the Golden Age of Gas.

I then used Stewart Brand’s Four Environmental Heresies to frame my new perspective on “Being Green.”

-population growth stablising and the world is not over-populated;
-cities are green
-nukes are green
-genetic engineering is green

I then gave a brief explanation of the Environmental Transition- the idea that environmentalism is a product of wealth and industrial growth rather than a reaction to it, and told the story from Shellenberger and Nordhaus’ book Breakthrough about the fires on the Cuyahoga River:cuyahoga_fire650

In June 22nd 1969 Time Magazine showed this photo of burning oil on Cuyahoga River with the caption
“The Price of Optimism” and it became emblematic of start of the US Environmental Movement.

The problem was, the photo was not from the 1969 fire, which has burned out in half-an-hour before the Time photographer could get there- but from an earlier and much more severe fire from 1952. In fact, there had been fires on the Cuyahoga river for a hundred years, some of them burning for days and causing loss of life: but the society had not yet reached a level of wealth and development- which would support universities with Environmental Societies- until much later. Poor people are not generally environmentalists- they have more expressing concerns, but once society has a critical mass of relatively affluent educated people with time on their hands, then industry is compelled to clean up its act.

I concluded my presentation with a quotation from Daniel Botkin’s book The Moon in the Nautilus Shell.:

Our perspective, ironically in this scientific age, depends on ancient myths and deeply buried beliefs. To gain a new view, one necessary to deal with global environmental problems, we must break free of old assumptions and myths about nature and ourselves while building on the scientific and technical advances of the past.

Dan Boyle followed me and began by expressing surprise to find himself having to defend the broad thrust of the environmental movement from the past few decades. He began by emphasising his agreement that Luddism is false, and that greens depend upon science and technology;

but seemed to struggle to hide some exasperation at my reference to Lomborg: “It is NOT the case that you burn your hydrocarbons and then clean up afterwards”- rather missing the point about the environmental transition, because of course that is precisely what the greens have been doing, otherwise we would never have embarked on industrialisation in the first place: the greens would have stopped us!

Dan’s main points seemed to be a bunch of Green Herrings: the supposed rallying cries of “bigger faster more” are the problem; untrield technology is dangerous and we should proceed with greater caution;
while his reference to dangers of the “chemical soup” used in frakking, and from “cross-contamination” from genetic engineering belie his claim to environmentalism being underpinned by science. Not to mention his suggestion that we can have “smaller and more efficient” wind turbines- surely not? To become more efficient, wind turbines can only do one thing: get bigger, due to well-understood laws of physics concerning wind-speed increasing to the square of the altitude/height and rotor span’s ability to collect the diffuse wind energy from a given space.

In the discussion and questions afterwards I was challenged quite strongly on nuclear waste issues, and general “Pandora’s Box” concerns about whether naughty humans should really be trusted with technology.

Dan Boyle made the very good point that at a meeting he had attended recently in the midlands concerning the proposed giant wind farm there, anti-wind activists used the same rhetoric and alarmism used by the anti-nuclear lobby, even including the threat of radiation- from wind turbines!

A popular theme seemed to be that rather than constantly striving for more energy sources, we should just use less. “Let’s turn out the lights then!” I said looking up to the ceiling at the dozens of lights that were probably consuming more energy that evening than I would at home in a year. My personal experience of living off the grid was apparently not persuasive however, and when I pointed out that there are still a couple of billion people without electricity at all in the world, I was told, “They can just use the Gravity Light!”

“Would you use one?”

“Well, it would be great for an outdoor light or something.”

Indeed it would, and for those without electric lights of any kind, this remarkable invention will surely be a wonderful boon. But for those who think that we can or will do anything other than make cosmetic changes in our energy usage, that “powerdown” can in some way substitute for cheap reliable electricity supply, should contemplate what life might be like if one or two gravity lights is all you ever have as a light supply, for the rest of your lives, ie without development.

Several people came up to me afterwards and thanked me for a thought-provoking perspective, while others took a more conventional green- perspective, concerned more about a presumed loss of contact with Nature, the virtues of the simple life and the insanity of endless growth rather than addressing the concerns of the poor. “We are all too greedy in this country!” proclaimed Eanna at one point.

But as Colin McInnes shows in this award-winning essay, growth is not just a matter of extraction and consumption, but is also about complexity:

While innovation-driven growth has delivered immense improvements to the human condition, it is also the means through which human needs can be gradually decoupled from the environment. Growth emerges from productivity, doing more with less. For example, new additive manufacturing technologies, so-called ‘3D printers’, look set partly to replace the wasteful subtractive manufacturing of machine tools. In contrast, in coming down from our oil high, as advocated by {Richard} Heinberg, we could regress to using whale oil for lighting, as was the case prior to commercial oil production. But this hardly constitutes progress, economic or environmental….

The real worry of Heinberg’s vision of a post-growth world is his straight-faced assertion that ‘there should be [an] increasing requirement for local production and manual labour’. This chilling claim is more Year Zero than zero growth. A return to carbohydrate-fuelled manual labour may be appealing to Heinberg and others as a means of powering down our lives and reconnecting with the land. But he shouldn’t expect a long queue of volunteers.

Maybe not- but he could well expect a long line of green ideologues who have forgotten that their green ideas are only possible because of the benefits brought by the very techno-industrialism that they campaign against.

Greens are Just as anti-Science on Climate as on GE

Update: Keith Kloor has just told me on Twitter that he has also been critical of the term “denier” as he discusses on this post.– which certainly shows he is aware of the issues I am raising here; however, he does indeed use the term “denialism” in the post on Seralini, without any indication of what he is actually referring to, and thus seems to fall into exactly the same traps.

The anti-science tendencies and frequently evidence-free stance of the Green movement finds a recent major example with the publication last week of Seralini’s GE-corn/roundup-fed rat trial, complete with garish photos of rats puffed up with tumors, which is being used to create wide-spread fear and panic about the safety of eating genetically engineered food.

John Vidal in the Guardian provides an egregious example of defending the indefensible, for example defending Seralini for winning his libel case against Fellous, president of the French Association of Plant Biotechnology, who suggested Seralini might be biased by his funding sources; but then casually throws in his own equivalent slur – of guilt by association- with the comment that UC Davis “has close links to Monsanto and other GM companies” while providing no evidence whatsoever that this would in any way, or has in any way influenced the impartiality or compromised the integrity of the the biotech scientists working there.

(For the response of a public scientist to charges of “shill for Monsanto” read Kevin Folta’s superb piece here.)

There has been a vigorous response from scientists and bloggers condemning the study as hopelessly flawed. There were not enough subjects in the control groups. Not all the data was published (and there is, rather unusually, a petition of scientists calling for the release of same); there appears to be no statistical significance to the data we do have showing any meaningful difference between the groups, with some of the controls having a higher incidence of tumors than the test groups; and mysteriously, there appears to be no distinction between high-and low-dose groups of either the corn or Roundup, which the rats were also tested for (an appears to have the same effects), defying the basic premise of toxicology that it is all in the dose. The Sprague-Dawley rats used are well-known to be prone to developing cancer anyway after the (very long period for a rat) of 2 years.

In my opinion, the methods, stats and reporting of results are all well below the standard I would expect in a rigorous study – to be honest I am surprised it was accepted for publication.

More damning still, the Statistical Laboratory at the University of Cambridge note:

I am grateful for the authors for publishing this paper, as it provides a fine case study for teaching a statistics class about poor design, analysis and reporting. I shall start using it immediately.

There is another even more startling point here as well, raised by @mem-somerville and taken up by Worstall which is that all lab-rats in the US have been eating some RR GE-corn for over a decade because that is just what the feed happens to be, with no noticeable effects or difference with European lab-rats where GE corn is not grown.

Apart from these flaws and the condemnation of so many scientists, it is obvious that the Seralini study is a put-up job to discredit GE crops and manipulate the political process.Seralini heads CRIIGEN which is an anti-GE activist group, he has a history of controversial studies producing results that have not been replicated and fly in the face of hundreds of other GE safety studies; and one of the co-authors of the report and president of CRIIGEN , Dr Joël Spiroux de Vendomoisis, is a homeopath.
