Consortium Plans World's Largest Wind Farm in UK
A joint venture between Shell, E.On UK and Core Limited has for goal to build an offshore wind farm off the South-East coast of England. The power generation potential would be of 1,000 megawatts, making it the biggest in the world and allowing it to power about 25% of London, which would cut emissions of carbon dioxide (the main greenhouse gas) by 1.9 million tonnes a year. Currently, "the world's biggest offshore wind farm that's already in operation is Denmark's Nysted windfarm, which can produce 165 megawatts." The Alternative Energy Blog has details, and you can get a bit more info from the official sources.
