The recommendations of Bill McKibben and Ross Gelbspan, among others, attracted me to Sajed Kamal’s book The Renewable Revolution, and its subtitle was an additional enticement: How we can Fight Climate Change, Prevent Energy Wars, Revitalise the Economy and Transition to a Sustainable Future. The book is on a smaller scale than its subtitle might suggest. Kamal has long been involved in sustainable development and renewable energy as a teacher, project consultant and speaker. He is eloquent on the Sun as the energy source that connects all life, and it is solar energy that he sees as able to meet all humanity’s energy needs many times over, directly through light and heat and indirectly through wind, water movement and photosynthesis.

Renewable Energy: The Facts
Germany is a country which has attracted much attention for taking renewable energy technology seriously, not least because it has gained significant economic advantage in doing so. That lends interest to the publication of an English translation of the book, Renewable Energy: The Facts, by German writers Dieter Seifried and Walter Witzel. The authors write chiefly about the German experience, but the book is also relevant to an international audience. Renewable energy is often difficult to get a handle on. Claims and counter-claims jostle confusingly. Sober evaluations such as this book seeks to supply are helpful. The book sets out to provide straightforward information, albeit with the conviction that renewable energy can successfully replace the fossil-fuelled sources which have become so dangerous in their impact on climate change.
The politics of failure/the failure of politics
As an example of contradictory thinking it would be hard to better Energy and Resources Minister Gerry Brownlee this week. He was announcing that oil and gas exploration in New Zealand is to get a substantial boost in government resources, including funding to further the possible exploitation of deep-sea methane hydrates.
He made a plea for New Zealanders to consider the potential for an accelerated oil and gas discovery programme to be achieved in an environmentally responsible way.
“People need to shift their thinking on exactly this issue. The development of New Zealand’s natural resources and the protection of the environment are not mutually exclusive. It is only through a strong economy that New Zealand can afford the expenditure required to look after and improve our environment.”
Is it unfair to construe this as follows?
We need to mine more oil and gas, the burning of which will hasten dangerous climate change, in order to become rich enough to deal with dangerous climate change.
In fact of course, when Brownlee talks of the environment he is probably not thinking of climate change at all. He gives very little evidence of ever thinking of climate change.
The contradictions of which Brownlee is an example are deeply embedded in the political scene in a great many countries. There is very little indication that governments are preparing to stop the mining of fossil fuels. Indeed there’s every indication that they’re ready to increase it whenever it looks as if there could be an economic benefit in doing so. Even the monstrous environmental assault of the extraction of oil from the Canadian tar sands is justified by its proponents. American Senator Lindsey Graham, who once supported a US climate bill, announced recently on a visit to view operations that he was going to do all he could to make sure that the oil sands production was not impeded because of US policy. He remarked that its production “really blends in with the natural habitat”!
One risks being regarded as slightly mad in declaring that a rational New Zealand would leave any possible new oil and gas fields undisturbed, along with coal unless effective carbon capture and sequestration processes are in place. But that seems to me to be the sane view at this stage of our understanding of what greenhouse gas emissions are doing to the climate.
George Monbiot has been reflecting on gap between the grand announcements of governments about emissions reductions and the reality that they aren’t achieving them. In a bleak column this week he writes that the failure of the international political process to find a successor to Kyoto means that “there is not a single effective instrument for containing man-made global warming anywhere on earth.”
It’s not as if the warnings are getting weaker. They are clearly mounting as the evidence continues to accumulate. But “the stronger the warnings, the less capable of action we become.” We were mistaken to think that something might come out of the last 18 years of talk and bluster. Environmentalists tend to blame themselves, but there was no strategy sure of success. The powers ranged against us are too strong.
“Greens are a puny force by comparison to industrial lobby groups, the cowardice of governments and the natural human tendency to deny what we don’t want to see. To compensate for our weakness, we indulged a fantasy of benign paternalistic power – acting, though the political mechanisms were inscrutable, in the wider interests of humankind. We allowed ourselves to believe that, with a little prompting and protest, somewhere, in a distant institutional sphere, compromised but decent people would take care of us. They won’t. They weren’t ever going to do so.”
Monbiot concludes that we must stop dreaming about an institutional response that will never materialise and start facing a political reality we’ve sought to avoid. I guess here in New Zealand that means accepting that the juggernaut of “resource” exploitation is going to roll on and leading politicians are going to continue to talk as if they’re protecting the environment while they’re in the process of destroying it. It also means that only strong organised implacable challenge is likely to have any effect – there is a small ray of hope in the success of mobilised public opinion against mining in protected conservation areas, but whether that kind of mobilisation can be raised against fossil fuels remains to be seen.
It may be worth noting that another columnist this week found reason to sound more upbeat, though certainly not about his own country. Thomas Friedman, writing in the New York Times, lamented the failure of the US senate to pass the energy-climate bill but pointed to the seriousness with which Chinese Communists were by contrast tackling the climate change issue and turning it into an opportunity for the development of clean technologies. Friedman is inclined to optimism, as was apparent in his book Hot, Flat and Crowded, but he provides some basis for it in the case of China.
He quotes Peggy Liu, chairwoman of the Joint U.S.-China Collaboration on Clean Energy, a nonprofit group working to accelerate the greening of China.
“China’s leaders are mostly engineers and scientists, so they don’t waste time questioning scientific data…China is changing from the factory of the world to the clean-tech laboratory of the world. It has the unique ability to pit low-cost capital with large-scale experiments to find models that work.”
Friedman points to the way China has designated and invested in pilot cities for electric vehicles, smart grids, LED lighting, rural biomass and low-carbon communities.
It’s perhaps not much to pin hopes on, especially as coal continues to be used for much new power generation in China. But it may well yet be the case that burgeoning clean technologies will take us further than politicians can. In my inbox this morning was information from the Earth Policy Institute on the continuing rapid growth of solar photovoltaic cell production, described as the world’s fastest-growing power technology. China, Japan and Taiwan are the leading manufacturers. The writer acknowledges that it remains more expensive than fossil fuel-generated power, but points out that its costs are declining rapidly. If fossil fuels ceased to receive subsidies and were required to incorporate their currently externalised costs their relative cheapness would be exposed as only apparent.
Which is good reason to argue in New Zealand for more even-handed government investment in renewables by comparison with fossil fuel extraction. The absurdity of offering so much support for fossil fuels and so little for the green technologies on which our future, if we have one, will depend might be realised by some in our government if we keep on insisting. But it remains a hard slog.

The answer, my friend…
Some encouraging facts and figures are provided in an interview with the CEO of the European Wind Energy Association, Christian Kjaer, by Yale Environment 360. For the past two years 40 per cent of all new electricity generating capacity in Europe came from wind turbines. (Add solar and other renewables and that rises to 63 per cent.) From Spain to Sweden so many new turbines are being erected that Europe is on target to produce 15 per cent of its electricity from wind by 2020 and 50 per cent by 2050.
Kjaer puts the emergence of wind as Europe’s leading form of green energy down to a combination of government policies, entrepreneurial vision, and public support. Carrots and sticks are involved. The European Union provides tax credits, financial incentives, and priority access for renewable energy to the electricity grid to encourage the growth of wind, solar and other forms or renewables. The stick is the requirement that member states set renewable energy targets or face the possibility of being sued.
The result is that increasingly as plants fired by coal and natural gas reach the end of their lives they are being replaced by wind and solar power. The economic benefits of the transition are clear, with nearly 200,000 people currently employed in European wind power, rising to an estimated 450,000 by 2020. Kjaer has no doubt that green energy is an engine of job creation.
He thinks the early start that Europe gained in wind power, particularly in Spain and Germany and Denmark, gives them an advantage in the new industry and means they are reaping commercial benefits in terms of wind turbine manufacturing and activity further down the supply line. The high quality manufacturing sector, strongly supported by governments, should see Europe retaining an edge over the intensifying competition from Asian countries. “The winners of tomorrow’s energy wars,” he says, “are going to be those who understand how to develop new technology, deploy new technology and get the benefits of exporting that technology to the rest of the world.”
He speaks of the need for Europe to make a serious effort in terms of changing the way they operate their grids, and to move more quickly to develop an offshore grid for utilizing the offshore wind energy. Politicians need to give attention to optimizing and expanding the grid infrastructure to accommodate a larger amount of variable wind power in the system, and also other renewables.
“One of the main reasons for the strong political support for a supergrid is also that we want to create an internal [European] market for electricity, which of course, in the end, should give consumers the most affordable electricity. That’s the whole idea about the internal market, is that it would create the free movement over borders of goods, services, and in this case electricity at the lowest cost. And in order to create an internal market for electricity you need the infrastructure, just as you need roads to move goods around the European Union.”
Concerning policies required for a robust industry Kjaer speaks first of stable long-term frameworks for investing in renewables. Stable frameworks help the European industry by contrast with the US where the framework is unable to be predicted more than one or two years ahead. This means the US is not reaping the job creation benefits of wind energy; a lot of manufacturing has to be imported since no one’s going to invest in a factory in the United States if they don’t know how the market looks beyond the next two years.
As an aside, a news item today reported US steelworkers complaining that in the manufacture of wind turbines and solar panels China is breaking WTO rules by an array of subsidies, tax credits, cut-rate loans, and other policies that give Chinese companies a strong competitive advantage over foreign firms. If Kjaer is right they might do better to complain of their own government’s failure to support green energy development ahead of the fossil fuel industry which is still favoured by extensive subsidies.
To return to Europe. Kjaer identifies three elements in the stable framework Europe is providing for renewable energy. Financial support such as tax credit is one. Access to the grid is another:
“And what European legislation does, it mandated all 27 member states to give priority access to wind energy, which means that if you have a wind farm and a gas plant, and they’re planned projects, the wind energy should be connected first. And also, if you have plants operating on the system, electricity from the renewables plant gets fed into the grid first.”
The third element is more straightforward administrative procedures. Kjaer spoke of hopes of streamlining what in some European countries are extremely tortuous permission processes.
Asked about public opposition to the expansion of wind turbines, he acknowledged it was an issue, more so in some countries than others. Onshore turbines in the UK are particularly difficult.
“But it’s my feeling that the concern from locals is biggest in the beginning of a new market taking off. So the first thousand megawatts are much more difficult to install than the next thousand megawatts. Because people get used to them, they understand that they don’t make noise anymore — the turbines twenty years ago made quite a lot of noise, today you can’t hear them, almost, if you’re more than two hundred meters away.”
Asked whether 100 per cent renewable electricity by 2050 was possible Kjaer explained why he thinks it is:
“Almost two-thirds of our new capacity is from renewables. That figure was about 20 per cent in the year 2000. So in nine years we’ve gone from 20 per cent to 62 — by 2020 of course we can get to 100 per cent of new capacity. And if we can get in 2020 to a situation where all new capacity is renewables, then we will, by definition almost, have 100 per cent renewable electricity by 2050 because all the other power plants will be taken off [line].”
Infrastructure is the absolute key:
“ – we need to build an infrastructure that is different. But, again, our infrastructure in Europe is aging – we haven’t been building power lines since the ‘60s or ‘70s. It needs to be replaced anyway. So we need to make sure that the infrastructure is changed in a way that it accommodates 100 per cent renewable electricity by 2050.”
While I was preparing this post a newsletter coincidentally arrived from the New Zealand Wind Energy Association, welcoming the Government’s continued commitment to its target of 90 per cent renewable electricity by 2025 in the draft New Zealand Energy Strategy and affirming the part that wind generation is able to play.
“In New Zealand, wind generation has increased 10-fold since 2003, helping lift total renewable generation to recent highs of over 70%. With four wind farms currently under construction, together with other new and planned renewable projects, New Zealand is making progress towards the 90% target and the rewards that it brings to the economy and the environment.”
It points to the economic advantage of globally competitive electricity prices that will accrue to New Zealand in the development of its ample renewable energy resources.
“Electricity prices have increased significantly in recent years on the back of rising natural gas prices. Increasing use of renewables such as wind energy, which has no fuel or carbon emissions costs, is helping to check these rising prices.”
There’s a note of understandable exasperation in a section of the newsletter addressing the misinformation barrier which it says is bizarrely making it easier to obtain resource consent for new thermal generation than for renewable generation.
Such misinformation as this:
“In the last few months we’ve seen claims that a proposed wind farm won’t generate the amount of electricity that the developer estimates because wind generation varies with the wind. Such claims overlook that developers’ calculations already take the variable nature of wind generation into account. Developers usually identify both the installed generating capacity of the project in megawatts (or MW) and the total amount of electricity that they expect the project to generate in a year in gigawatt-hours (GWh). This estimate of generation takes into account the wind conditions at the site and that varying wind conditions affect generation.”
The newsletter points out that wind is proving itself in New Zealand on its own merits. (I would add, in spite of the unfair advantages enjoyed by fossil fuels which are only just beginning to have a modest price put on them.) Unlike other countries, New Zealand wind farms are not subsidised. A wind farm will be built here only when it can generate electricity at a cost that is competitive with other forms of generation.
The NZ wind resource is very strong by comparison with other parts of the world where wind farms are being installed. Our wind farms generate almost twice as much electricity per installed megawatt of capacity as the international average.
In response to the claim that new thermal generation is required as back up for new wind farms the newsletter responds that our existing hydro base is sufficient to balance about 2000MW of wind capacity without adding significantly to the price of electricity. Current wind energy capacity sits just under 500MW, so there’s obviously some distance to go before back up becomes a serious concern.
It’s the view of the newsletter that the considerable range of research and practical experience available regarding wind energy after more than 10 years operation in NZ and more than 20 years overseas reveals that many of the claims commonly heard in denigration of wind energy do not stand up to scrutiny.
So, this evidence from Europe and New Zealand, along with that from the US and from China among others, demonstrates that in spite of all its detractors wind generation is advancing rapidly. It’s heartening to see that there are governments prepared to offer the financial and policy support that it needs. Some point sneeringly to that and utter the dirty word ‘subsidies’. In a market place which doesn’t price the environmental costs of fossil fuels there is currently no other way of putting renewables on an equal footing. In any case the imperative to phase out emissions means that we must pay what it costs to do so, just as, for example, we are preparing to pay the costs of repairing the earthquake damage in Canterbury. There are some expenditures which can’t be avoided. Would that our Draft Energy Strategy would recognise that.
Ramping up renewables
There may be conflicting reports as to whether renewable energy can replace fossil fuels in time to significantly reduce carbon dioxide emissions, and there are still plenty of people in positions of authority, like our own Energy Minister, who see little reason to hurry the process. The heavy lobbying influence of big oil and coal interests remains powerful. But it’s heartening to be reminded from time to time that transition is nevertheless under way in many parts of the world and that it’s gathering pace. An Earth Policy Institute article has arrived in my inbox offering just such a reminder. It refreshes what Lester Brown had to say about the shift to renewable energy in his book Plan B 4.0.
I reviewed the book on Hot Topic last year, but at the risk of repeating myself I’ll report some of the points which he now reiterates and updates. The first is that the transition to energy powered by wind, solar and geothermal sources is moving worldwide at a pace and on a scale we could not have imagined even two years ago. Texas, the oil state, is a prime example. It has 9,700 megawatts of wind generating capacity online, 370 more in construction, and a huge amount in the development stage. When all of these wind farms are completed, Texas will have 53,000 megawatts of wind generating capacity—the equivalent of 53 coal-fired power plants. This will more than satisfy the residential needs of the state’s 25 million people, enabling Texas to export electricity, just as it has long exported oil.
South Dakota has begun development on a vast 5050-megawatt farm that when completed will produce nearly five times as much electricity as the state needs. It will become an exporter, as some ten American states and several Canadian provinces are planning to be.
Brown then moves across the Atlantic to point to the hopes of the Scottish government for the development of an enormous off-shore wind generating capacity of some 60,000 megawatts. I reported on Hot Topic a few months ago on a major survey which has identified North Sea potential from wind and wave of even larger potential, capable of producing six times as much electricity as is currently used in the UK. If joined to a northern super-grid it could enable access to a single European electricity market and export opportunity.
Algeria plans to build 6000 megawatts of solar thermal generating power for export to Europe via undersea cable
It’s not only the developed world that is embracing renewable energy on a rapidly growing scale. Brown instances Algeria’s plans to build 6000 megawatts of solar thermal generating power for export to Europe via undersea cable. He points to their awareness that they have enough harnessable solar energy in their vast deserts to power the entire world economy. Solar energy is clearly of enormous potential not only in the Mediterranean region but also in the south-west US and the Indian desert and China, and there is regular news of new developments in all of these areas.
Brown touches on Turkey where construction permits are being issued for 7,000 megawatts of wind generating capacity, in response to bids to build a staggering 78,000 megawatts. In Indonesia the state oil company Pertamina is responsible for developing most of a planned 6,900 megawatts of geothermal generating capacity.
“These are only a few of the visionary initiatives to tap the earth’s renewable energy. The resources are vast. In the United States, three states—North Dakota, Kansas, and Texas—have enough harnessable wind energy to run the entire economy. In China, wind will likely become the dominant power source. Indonesia could one day get all its power from geothermal energy alone. Europe will be powered largely by wind farms in the North Sea and solar thermal power plants in the North African desert.”
The 20th century saw the globalisation of the world energy economy as countries everywhere turned to oil, much of it from the Middle East. This century, says Brown, will see the localisation of energy production as the world turns to wind, solar and geothermal energy. It will also see the electrification of the economy.
“The transport sector will shift from gasoline-powered automobiles to plug-in gas-electric hybrids, all-electric cars, light rail transit, and high-speed intercity rail. And for long-distance freight, the shift will be from diesel-powered trucks to electrically powered rail freight systems. The movement of people and goods will be powered largely by electricity. In this new energy economy, buildings will rely on renewable electricity almost exclusively for heating, cooling, and lighting.”
Can renewable energy be expanded fast enough? Brown thinks so, encouraged by the phenomenon of the extraordinary growth of the communications and information economies in only the last thirty years. Others don’t. Barry Brook in Australia is one, with his views summed up in this recent article and much more on his Brave New Climate website. Not that he’s arguing for fossil fuels – in his view nuclear power is the only technology that can get us there fast enough and economically enough.
Lester Brown falls back on the analogy of the Second World War when the American economy changed direction with extraordinary speed and prospered in doing so. He’s not alone in sounding this theme, but he was an early proponent of it. The difficulty with this concept is that our societies are hardly yet ready to see climate change in the stark terms which obtained in 1939 and 1941.
Whether renewables will be ratcheted up quickly enough or not they certainly represent one of our best hopes of containing climate change impacts. Don’t forget to tell Gerry Brownlee so before September 2, when submissions on the new draft energy strategy close. I’ve said elsewhere on Hot Topic what I see as wrong with the draft. Simon Boxer of Greenpeace has put it succinctly:
“It’s a document that lacks vision and goals. It shows that the Energy and Resources Minister Gerry Brownlee is ignoring the climate crisis. It’s a route map to a dead end.
“The Government’s energy strategy prioritises drilling and mining for more oil and coal, while providing virtually no stimulation for the development of renewable energy and clean technology. It fails to acknowledge the seriousness of climate change and makes no attempt to set measurable emissions reduction targets.”
If you’d like some suggestions the Greens offer a thoughtful submission guide. If you’re lacking time a shortcut is offered by Greenpeace or WWF . Many of the 40,000 submissions received by the government on Brownlee’s proposals to mine conservation land no doubt used form statements provided by organisations. They still count, so use one of the offered quick responses rather than pass the opportunity by.
