“Renewable energy is growing faster than ever before…. Many view such news as rays of hope in a rapidly destabilizing climate. We all need some good news – but is renewables expansion really the good news people like to think? Can we really put our hopes for stabilizing the climate into trying to simply replace the energy sources in a growth-focused economic and social model that was built on fossil fuels? Or do we need a far more fundamental transition towards a low-energy economy and society?” —Almuth Ernsting
Almuth Ernsting, a co-director of Biofuelwatch, critically analyses the much-celebrated renewable energy success stories coming out of Germany, Norway and Denmark. She comes to a startlng conclusion – “Thus, on closer inspection, many of the “great renewable energy successes” don’t look so great after all.” Moreover, she quotes one scientist who argues — “To talk about ‘renewable energy’ or ‘sustainable energy’ is an oxymoron, as is ‘sustainable mining’ or ‘sustainable development.’ The more energy we use, the less sustainable is humanity.”
Ms Ernsting lays out her evidence in the following article, accessible by clicking on the linked title. Alternatively, below is a repost with added subheadings and highlighted text to bring to the fore the author’s key points. Don’t miss the SEE ALSO link at the bottom of this post to a 4:00-minute video of Almuth talking about the connection between biofuels and deforestation and peat fires.
First – two key definitions
Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat. Renewable energy replaces conventional fuels in four distinct areas: electricity generation hot water/space heating, motor fuels, and rural (off-grid) energy services. Bioenergy is renewable energy made available from materials derived from biological sources. Biomass is any organic material which has stored sunlight in the form of chemical energy. As a fuel it may include wood, wood waste, straw, manure, sugarcane, and many other by-products from a variety of agricultural processes.
Although “renewable” energy is growing faster than ever before, it is neither carbon neutral, “clean” nor sustainable. We need to transform into low-energy societies that meet human – not corporate – needs.
Renewable energy is growing faster than ever before. Sure, some countries are lagging behind, but others are setting widely praised records.
Germany has installed over 24,000 wind turbines and 1.4 million solar panels, and renewables generate 31 percent of the country’s electricity on average – and as much as 74 percent on particularly windy or sunny days. According to the German government, 371,400 jobs have been created by renewable energy. Norway generates 99 percent of its electricity from renewable energy. Denmark already generates 43 percent of electricity from renewables and aims to phase out fossil fuel burning by 2050.
Many view such news as rays of hope in a rapidly destabilizing climate. We all need some good news – but is renewables expansion really the good news people like to think? Can we really put our hopes for stabilizing the climate into trying to simply replace the energy sources in a growth-focused economic and social model that was built on fossil fuels? Or do we need a far more fundamental transition towards a low-energy economy and society?
Problem – renewable energy hasn’t stopped record fossil fuel burning
Here’s the first problem with celebratory headlines over renewables: Record renewable energy hasn’t stopped record fossil fuel burning, including record levels of coal burning. Coal use is growing so fast that the International Energy Authority expects it to surpass oil as the world’s top energy source by 2017.
Problem – no form of large-scale energy, including renewables, is carbon neutral
Perhaps the 1,500 gigawatts of electricity produced from renewables worldwide have prevented a further 1,500 gigawatts of fossil fuel power stations? Nobody can tell. It’s just as possible that renewables have simply added 1,500 gigawatts of electricity to the global economy, fueled economic growth and ever-greater industrial resource use. In which case, far from limiting carbon dioxide emissions worldwide, renewables may simply have increased them because, as discussed below, no form of large-scale energy is carbon neutral.
As long as energy sources that are as carbon-intensive and destructive as fossil fuels are classed as “renewable,” boosting renewable energy around the world risks doing more harm than good.
Germany, a case in point – 87.8 percent of its total energy use continues to come from fossil fuels
Germany’s Energy Transition illustrates the problem: Wind turbines and solar panels have certainly become a widespread feature of Germany’s landscape.
The bulk of Germany’s renewables comes from bioenergy, which contributes to resource degradation at home and abroad
The picture looks even worse when one examines the mix of energy classed as renewable in Germany:
Germany’s wind turbines and solar panels have hardly made a dent in its fossil fuel use and carbon emissions
On closer examination, therefore, 24,000 wind turbines and 1.4 million solar panels have scarcely made a dent in Germany’s fossil fuel burning and carbon emissions.
In Norway’s case, its economy remains heavily dependent on oil and gas exports
Norway’s situation is unique in that virtually all of the country’s electricity is generated from hydro dams, which were gradually expanded over the course of more than a century.
And its transfer of hydro dam technology to developing countries causes flooding, land loss, soil erosion, forest destruction, population displacement, increase in methane emissions and more
Norway’s own hydro dams – many of them small-scale – have raised little controversy but the same cannot be said for Norway’s efforts to export this model to other countries. The Norwegian government and the state-owned energy company Statkraft have been at the forefront of financing controversial dams and associated infrastructure in Laos, India, Malaysian Borneo and elsewhere. One example is Statkraft’s joint venture investment in a new dam in Laos that has displaced 4,800 people and is causing flooding, erosion, and loss of fisheries and land on which people relied for growing rice.
Another example is Norwegian aid for transmission lines for mega-dams in Sarawak, a Malaysian province in Borneo which has seen vast areas of tropical rainforest – and the livelihoods of millions of indigenous peoples – sacrificed for palm oil, logging and also hydro power. One dam alone displaced 10,000 people and at least 10 more dams are planned, despite ongoing resistance from indigenous peoples. Far from being climate-friendly, hydro dams worldwide are associated with large methane emissions – with one study suggesting they are responsible for 25 percent of all human-caused methane emissions and over 4 percent of global warming. The disastrous consequences of Norway’s global hydro power investment illustrates the dangers of the simplistic view that anything classed as renewable energy must be climate-friendly and merits support.
In Denmark’s case, its use of biofuels is worse for the climate than equivalent quantities of oil once all external factors are included
What about the much-heralded renewable transition of Denmark? There coal use is falling and around 21 percent of total energy is sourced from renewables. Denmark holds the world record for wind energy capacity compared to population size. Unlike many other countries where wind energy is firmly controlled by large energy companies, Denmark has seen strong support for locally owned wind energy cooperatives, widely considered an inspiring example of clean, community-controlled energy. Nonetheless, wind energy in Denmark accounted for just 3.8 percent of Denmark’s total energy use in 2010.
Bioenergy accounts for a far greater percentage of Denmark’s “renewable energy” than does wind – and indeed for a greater share in the country’s overall energy mix than is the case in any other European country. As in Germany, Denmark’s bioenergy includes biofuels for transport, which studies show tend to be worse for the climate than equivalent quantities of oil once all the direct and indirect emissions from deforestation, peatland destruction and other land use change associated with them are accounted for. And it includes wood pellets, with Denmark being the EU’s, and likely the world’s, second biggest pellet importer after the United Kingdom. Most of those pellets come from the Baltic states and Russia, from countries where clear-cutting of highly biodiverse forests is rampant. Studies show that burning wood from whole trees can be worse for the climate than burning coal over a period of decades or even centuries.
Changing the catch-all definition of ‘renewables’ to exclude carbon-intensive and destructive energy sources is not the answer
Clearly, the current catch-all definition of “renewables” is a key problem: Defining methane-spewing mega-dams, biofuels, which are accelerating deforestation and other ecosystem destruction, or logging forests for bioenergy as “renewable” helps policy makers boost renewables statistics, while helping to further destabilize planetary support systems. As long as energy sources that are as carbon-intensive and destructive as fossil fuels are classed as “renewable,” boosting renewable energy around the world risks doing more harm than good.
A saner definition of “renewable energy” clearly is vital but would it open the door toward 100 percent clean and plentiful energy? Comparing the rate of wind energy expansion in Denmark and wind and solar power expansion in Germany with the tiny contribution they make to both countries’ total energy supply indicates otherwise.
Life-cycle impacts of wind and solar are smaller than fossil fuels but the manufacturing impacts are not benign
Wind and solar power require far less land per unit of energy than biomass or biofuels, but the area of land needed to replace fossil fuel power stations with, say, wind turbines is vast nonetheless. According to a former scientific advisor to the UK government, for example, 15 offshore wind turbines installed on every kilometer of the UK coastline would supply just 13 percent of the country’s average daily energy use. And offshore turbines are more efficient than onshore ones.
Researchers agree that the life-cycle impacts of wind and solar power on the climate and environment are definitely smaller than those of fossil fuels, as long as turbines and panels are sensibly sited (not, for example, on deep peat). But this doesn’t mean that the impacts are benign. Generating that 13 percent of UK energy from offshore wind would require wind turbines made of 20 million tons of steel and concrete – more than all the steel that went into US shipbuilding during World War II. Steel manufacturing is heavily dependent on coal, not just as a fuel for the furnaces but because it is needed to enrich the raw material, iron ore, with carbon to make it stable. And concrete is hardly “carbon neutral” either – cement (a key component) accounts for 5 percent of global carbon dioxide emissions.
Solar PV panels are up to four times as energy and carbon-intensive to produce as wind turbines:
Talk of carbon-free, clean energy sustainable solutions is an oxymoron
Zero-carbon, clean energy? Well, no. And yet, there are no large-scale energy sources with lower carbon emissions and less harmful environmental impacts than wind and solar power. As one scientist argues from the perspective of thermodynamics: “To talk about ‘renewable energy’ or ‘sustainable energy’ is an oxymoron, as is ‘sustainable mining’ or ‘sustainable development.’ The more energy we use, the less sustainable is humanity.”
The ultimate solution — return to a low-energy, low consumption, pre-1973 lifestyle
We certainly need to swiftly end fossil fuel burning and the destruction of ecosystems and that will require us to rely on the least harmful energy sources such as wind and solar power. But the myth of plentiful “clean” energy stops us from focusing on the far deeper changes needed – a transformation toward a low-energy society.
A depressing conclusion? Not necessarily. As UK climate change campaigner and author George Marshall has pointed out, we could cut flights (and probably all transport emissions) and slash energy used for home heating by 80 percent overnight by going back to the way people used to live as short a time ago as 1972, provided we used home insulation and efficient boiler technology developed since then. Instead, 40 years of efficiency gains have been wiped out by ever-greater consumption. Yet UK “personal satisfaction” surveys show that people’s sense of satisfaction or happiness peaked in 1970. Once people’s basic needs for energy are met, rising energy use remains vital for corporate profits and economic growth, but not for people’s quality of life.
Transition to a low-energy society must be a priority for anyone aware of the urgency and gravity of climate change
Most readers will have never lived in a low-energy society. Imagining what such a society might look like and how to move toward the transformation required to get there, and to overcome the corporate interests that depend on profits from ever rising energy use, must be priorities for anyone aware of the seriousness of climate change.
Daunting no doubt, but once we’ve abandoned faith in plentiful “clean” energy, we can finally make a start.
