Here's more "loco" stuff that I just made up: New wind turbine farce: How they take power from the National Grid even when they are NOT generating any electricity Wind turbines use electricity to keep spinning in cold weather to stop icing Off-shore turbines only operate when the wind is between 10 and 50 mph Wind energy can produce enough electricity to power 8.8 million homes But low wind speeds have cut the renewable output By Rosie Taylor for the Daily Mail Published: 14:44 EST, 1 January 2015 \| Updated: 13:06 EST, 2 January 2015 Off-shore wind turbines take power from the National Grid when not generating electricity, it has emerged. They use electricity to keep their blades rotating slowly in cold weather to prevent them icing up and to power the systems which turn the blades into the wind. It costs around twice as much to produce electricity using offshore wind than at traditional coal and gas-fired power stations. Scroll down for video +2 Off-shore wind turbines take power from the National Grid when not generating electricity, file photo Critics say it is a ‘folly’ that turbines need National Grid power even when idle. But experts counter by saying that all methods of producing power need to use electricity to function. The issue has flared up after one resident in North Wales told how he had observed more than 100 turbines off the coast ‘idling very slowly’ in freezing conditions. Brian Christley, of Conwy, raised his concerns in a letter to The Daily Telegraph. He wrote: ‘Over the weekend just gone – the coldest of the year so far – all 100-plus offshore wind turbines along the North Wales coast were idling very slowly, all using grid power for de-icing and to power their hydraulic systems that keep the blades facing in the same direction.’
