World's Biggest Offshore Wind Farm Switched On in Britain
http://spectrum.ieee.org/energywise/green-tech/wind/worlds-biggest-offshore-wind-farm-switched-on-in-britain
Around a year and a half ago, the Walney wind farm in the Irish Sea started spinning and prepared to relish the title of being "biggest in the world." It ended up enjoying that status a bit longer than expected, but the London Array, off the coast of Kent, now leaves Walney and its 367 megawatts in the dust.
Some numbers: 175 turbines. 630 megawatts. Half a million homes. 100 square kilometers. 450 kilometers of offshore cabling.
In other words, it's pretty big. The speed at which these enormous projects are popping around in the waters around the U.K. is impressive, especially considering the ongoing difficulties with getting even a single offshore turbine up and running in the U.S. (Cape Wind might have one by next year! Maybe!) There are now around 20 distinct offshore wind farms around the U.K., generating enough power for 2.3 million homes; when all offshore turbines that are spinning, in construction, or planned are combined, they total 15 gigawatts of capacity
about a quarter of the entire U.S. onshore wind power capabilities.
