The great wind delusion has hijacked our energy policy


Anyone impressed by the efficient way in which Britain has organised the Olympic Games might consider the stark contrast provided by the shambles of our national energy policy – wholly focused as it is on the belief that we can somehow keep our lights on by building tens of thousands more wind turbines within eight years. At one point last week, Britain’s 3,500 turbines were contributing 12 megawatts (MW) to the 38,000MW of electricity we were using. (The Neta website, which carries official electricity statistics, registered this as “0.0 per cent”).

It is 10 years since I first pointed out here how crazy it is to centre our energy policy on wind. It was pure wishful thinking then and is even more obviously so now, when the Government in its latest energy statement talks of providing, on average, 12,300MW of power from “renewables” by 2020.

Everything about this is delusional. There is no way we could hope to build more than a fraction of the 30,000 turbines required. As the windless days last week showed, we would have to build dozens of gas-fired power stations just to provide back-up for all the times when the wind is not blowing at the right speed. But, as more and more informed observers have been pointing out, the ministers and officials of the Department of Energy and Climate Change (DECC) seem to live in a bubble of unreality, without any practical grasp of how electricity is made, impervious to rational argument and driven by an obsession that can only end in our computer-dependent economy grinding to a halt.

The latest attempt to get them to face reality is by Prof Gordon Hughes, a former senior adviser on energy to the World Bank, now a professor of economics at Edinburgh, whose evidence to the Commons committee on energy and climate change has now been published on the website of the Global Warming Policy Foundation. His most shocking finding is that the pursuit of our Climate Change Act target – to reduce Britain’s CO2 emissions by 80 per cent by 2050 – would cost us all £124 billion by 2020, or £5,000 for every household in the land: not just to build tens of thousands of absurdly subsidised wind turbines, but also for the open-cycle gas-fired power stations needed to provide back-up. To guarantee the same amount of power from combined-cycle gas-fired plants would cost £13 billion, barely a tenth as much.
