Wind Turbines ‘Only Lasting for Half as Long as Previously Thought’

Wind farms have just half the useful lifespan which has been claimed, according to new research which found they start to wear out after just 12 years.
A study of almost 3,000 turbines in Britain – the largest of its kind – sheds doubt on manufacturers claims that they generate clean energy for up to 25 years, which is used by the Government to calculate subsidies.
Professor Gordon Hughes, an economist at Edinburgh University and former energy advisor to the World Bank, predicts in the coming decade far more investment will be needed to replace older and ineffective turbines – which is likely to be passed on in higher household electricity bills.
He said the performance of the UK’s wind turbines over the past 11 years had ‘deteriorated markedly’ and that ‘the subsidy regime is extremely generous if investment in new wind farms is profitable despite the decline in performance due to age and over time.’
The research will fuel criticism of wind farms which are already unpopular among many local communities who say they blight the landscape, generate noise and may disrupt wildlife.
But the government which plans to increase the number of turbines from the current 3,873 to 10,000 within the next decade, insists they are essential to fight climate change.
