"A study in the Netherlands found that turning back-up gas power stations on and off to cover spells when there is little wind actually produces more carbon than a steady supply of energy from an efficient modern gas station.
The research is cited in a new report by the Civitas think tank which warns that Britain is in danger of producing more carbon dioxide (CO2) than necessary if the grid relies too much on wind.
Wind turbines only produce energy around 30 per cent of the time. When the wind is not blowing - or even blowing too fast as in the recent storms - other sources of electricity have to be used, mostly gas and coal.
However it takes a surge of electricity to power up the fossil fuel stations every time they are needed, meaning more carbon emissions are released."
