Thousands of Britain’s wind turbines will create more greenhouse gases than they save, according to potentially devastating scientific research to be published later this year.
The finding, which threatens the entire rationale of the onshore wind farm industry, will be made by Scottish government-funded researchers who devised the standard method used by developers to calculate “carbon payback time” for wind farms on peat soils.
Wind farms are typically built on upland sites, where peat soil is common. In Scotland alone, two thirds of all planned onshore wind development is on peatland. England and Wales also have large numbers of current or proposed peatland wind farms.
But peat is also a massive store of carbon, described as Europe’s equivalent of the tropical rainforest. Peat bogs contain and absorb carbon in the same way as trees and plants — but in much higher quantities.
British peatland stores at least 3.2 billion tons of carbon, making it by far the country’s most important carbon sink and among the most important in the world.
Wind farms, and the miles of new roads and tracks needed to service them, damage or destroy the peat and cause significant loss of carbon to the atmosphere, where it contributes to climate change.
Writing in the scientific journal Nature, the scientists, Dr Jo Smith, Dr Dali Nayak and Prof Pete Smith, of Aberdeen University, say: “We contend that wind farms on peatlands will probably not reduce emissions …we suggest that the construction of wind farms on non-degraded peats should always be avoided.”
Dr Nayak told The Telegraph: “Our full paper is not yet published, but we should definitely be worried about this. If the peatland is already degraded, there is no problem. But if it is in good condition, we should avoid it.”
Another peat scientist, Richard Lindsay of the University of East London, said: “If we are concerned about CO2, we shouldn’t be worrying first about the rainforests, we should be worrying about peatlands.
“The world’s peatlands have four times the amount of carbon than all the world’s rainforests. But they are a Cinderella habitat, completely invisible to decision- makers.”
One typical large peat site just approved in southern Scotland, the Kilgallioch wind farm, includes 43 miles of roads and tracks. Peat only retains its carbon if it is moist, but the roads and tracks block the passage of the water.
The wind industry insists that it increasingly builds “floating roads,” where rock is piled on a textile surface without disturbing the peat underneath.
But Mr Lindsay said: “Peat has less solids in it than milk. The roads inevitably sink, that then causes huge areas of peatland to dry out and the carbon is released.”
Mr Lindsay said that more than half of all British onshore wind development, current and planned, is on peat soils.
In 2011 the Scottish government’s nature protection body, Scottish Natural Heritage, said 67 per cent of planned onshore wind development in Scotland would be on peatland.

Growing oil palm to make ‘green’ biofuels in the tropics could be accelerating the effects of climate change, say scientists.
Researchers from Bangor University found the creation of oil palm plantations are releasing prehistoric sources of carbon dioxide back into the atmosphere.
The findings throw into doubt hopes that biofuels grown in the tropics could help cut greenhouse gas emissions.
Working as part of an international team, the north Wales scientists looked at how the deforestation of peat-swamps in Malaysia, to make way for oil palm trees, is releasing carbon which has been locked away for thousands of years.
It is feared this carbon will be attacked by microbes and produce the greenhouse gas, carbon dioxide. The Bangor researchers say the ancient carbon comes from deep in the soil, which as the effects of deforestation take hold, breaks down and dissolves into the nearby watercourses.
When describing their work which appears in Nature, Prof Chris Freeman commented: “We first noticed that the ditches draining areas converted to palm oil plantations were loaded with unusually high levels of dissolved carbon back in 1995, but it was not until my researcher Dr Tim Jones took samples to measure the age of that carbon that we realised we were onto something important”. Dr Jones added “We were amazed to discover that the samples from Malaysian oil palm plantations contained the oldest soil-derived dissolved organic carbon ever recorded.”
The Bangor University researchers measured the water leaching from channels in palm oil plantations in the Malaysian peninsular which were originally Peatland Swamp Forest. There are approximately 28,000 km2 of industrial plantations in peninsular Malaysia, Sumatra and Borneo with even more planned, making them a major contributor to peatswamp deforestation in the region. Prof Freeman commented; “Our results are yet another reminder that when we disturb intact peatswamps and convert them to industrial biofuel plantations, we risk adding to the very problem that we are trying to solve”
Prof Freeman added: “We have known for some time that in South East Asia, oil palm plantations were a major threat to biodiversity, including the habitat for orang-utans, and that the drainage could release huge amounts of carbon dioxide during the fires seen there in recent years. But this discovery of a “hidden” new source of problems in the waters draining these peatlands is a reminder that these fragile ecosystems really are in need of conservation.”

Biofuels will serve the interests of large industrial groups rather than helping to cut carbon emissions and ward off climate change, according to research to be published in the International Journal of Environment and Health this month.
Simone Vieri of the University “La Sapienza” of Rome, Italy, explains that, in its policies to combat climate change, the European Union has planned to increase to 10% the share of fuel derived from biofuels on the market by 2020. It has focused attention on first-generation biofuels, made from the conversion of plant material which can be grown specifically for fuel production, such as corn, soy, sugarcane or palm oil. It has given only a secondary role to second-generation biofuels, made from agricultural and woody crop biomass, including waste and by-products.
Vieri suggests that, “In 2020 the EU won’t be able to keep to its 10% biofuels goal using only European agricultural production, but will have to continue importing the greatest part of raw materials, or biofuels.”
In this frame, Vieri explains that, “The EU’s decision to focus on the first-generation biofuels, raises many doubts.” In particular, the approach seems to favour several issues. For instance, it favours production systems that are in competition with traditional agriculture for use of resources and production factors, he says. Additionally, to encourage agro-industrials models, such as those on which the production of first generation biofuels is based, might compromise the possibility of developing models based on multifunctional agriculture and, then, on the production of energy from agriculture waste and by-products rather than from dedicated products.
The adoption of first-generation biofuels sometimes leads to exploitation of human and environmental resources of poorer countries, adds Vieri, as they are commonly the source of many of the agricultural raw materials used for production of biofuels. Moreover, agricultural production processes that change land use can lead to zero net benefit in terms of emissions reduction.
Other problems that arise when reliance is placed on first-generation biofuels lie with the economics. Financial market speculation strengthens the link between the price of oil and the price of the main agricultural raw materials, Vieri says. Furthermore, an increase, or instability of agricultural products’ prices, weighs heavily on poorer nations and their food security.
In this context “the choice to promote first generation biofuels is an example of how politics places the protection of the interests and profit strategies of a restricted number of subjects before the costs and benefits to be had on a wider scale,” adds Vieri.
Vieri adds that the “green economy” model might break new ground if it were to prove able to facilitate reduced emissions and allow economic growth and development with direct benefit to society itself rather than the profits of multinationals.

Construction on Brazil’s megadam, Belo Monte, has been halted again as around 150 demonstrators, most of them from nearby indigenous tribes, have occupied the main construction site at Pimental. Over a hundred indigenous people joined local fishermen who had been protesting the dam for 24 days straight. Indigenous people and local fishermen say the dam will devastate the Xingu River, upending their way of life.
“The renewed occupation of the project’s earthen cofferdams paralyzed construction works, while indigenous protestors seized the keys of trucks and tractors forcing workers to leave the strategic Pimental work camp on foot,” reads a press release from the NGO Amazon Watch. Around 900 workers were sent home.
This is the second occupation attempt in less than six months. Over the summer some 300 indigenous people sustained an occupation of the dam for 21 days, before breaking it off though little headway was made in talks with consortium building the dam, Norte Energia.
The Belo Monte dam, which would be the world’s third largest, has been plagued by controversy from its origin decades ago; the battle for the dam has been fought both in Brazil’s courts and on the international stage. If built, the dam will flood an estimated 40,000 hectares of present rainforest and could push some fish species to extinction. In addition, 16,000 people will be displaced according to the government, though some NGOs say the number is more likely double that.
Despite the impacts, the dam has been strongly supported by Brazilian President Dilma Rousseff, and every legal injunction against the dam has been overturned. Norte Energia has filed with a local court for repossession of the construction sties.
Indigenous groups say the construction of the dam is already imperiling their way of life, as the Xingu river becomes more difficult to navigate. They have also said they have no intention of leaving until Norte Energia meets their demands.
“We are witnessing the devastation of this land. The island of Pimental was completely destroyed, with a sole tree left standing, and the water is putrid. It is very shocking,” an protestor told Amazon Watch.
Dams are often described as ‘green’ energy source, however in the tropics they actually release significant methane emissions due to rotting vegetation. Although it has a shorter life than carbon, methane is a far more potent greenhouse gas.

From the air it looks like a huge lake, fed by many tributaries, but on the ground it turns out to be a murky expanse of water, in which no fish or algae can survive. The shore is coated with a black crust, so thick you can walk on it. Into this huge, 10 sq km tailings pond nearby factories discharge water loaded with chemicals used to process the 17 most sought after minerals in the world, collectively known as rare earths.
The town of Baotou, in Inner Mongolia, is the largest Chinese source of these strategic elements, essential to advanced technology, from smartphones to GPS receivers, but also to wind farms and, above all, electric cars. The minerals are mined at Bayan Obo, 120km farther north, then brought to Baotou for processing.
The concentration of rare earths in the ore is very low, so they must be separated and purified, using hydro-metallurgical techniques and acid baths. China accounts for 97% of global output of these precious substances, with two-thirds produced in Baotou.
The foul waters of the tailings pond contain all sorts of toxic chemicals, but also radioactive elements such as thorium which, if ingested, cause cancers of the pancreas and lungs, and leukaemia. “Before the factories were built, there were just fields here as far as the eye can see. In the place of this radioactive sludge, there were watermelons, aubergines and tomatoes,” says Li Guirong with a sigh.
It was in 1958 – when he was 10 – that a state-owned concern, the Baotou Iron and Steel company (Baogang), started producing rare-earth minerals. The lake appeared at that time. “To begin with we didn’t notice the pollution it was causing. How could we have known?” As secretary general of the local branch of the Communist party, he is one of the few residents who dares to speak out.
Towards the end of the 1980s, Li explains, crops in nearby villages started to fail: “Plants grew badly. They would flower all right, but sometimes there was no fruit or they were small or smelt awful.” Ten years later the villagers had to accept that vegetables simply would not grow any longer. In the village of Xinguang Sancun – much as in all those near the Baotou factories – farmers let some fields run wild and stopped planting anything but wheat and corn.
A study by the municipal environmental protection agency showed that rare-earth minerals were the source of their problems. The minerals themselves caused pollution, but also the dozens of new factories that had sprung up around the processing facilities and a fossil-fuel power station feeding Baotou’s new industrial fabric. Residents of what was now known as the “rare-earth capital of the world” were inhaling solvent vapour, particularly sulphuric acid, as well as coal dust, clearly visible in the air between houses.
