Atlantic Wind Connection would link wind farms over hundreds of miles

During the last ice age, glaciers a mile high pushed several dozen cubic miles of rock, sand and debris into the ocean off North America’s mid-Atlantic coast, creating a broad shelf that extends up to 40 miles offshore. This long, flat stretch of seabed and the shallow, windy waters that cover it make the ideal spot for dozens of offshore wind farms—and if all goes well, the network that would link those turbines together and back to the coast will soon be in place.
Seven miles off the coast of Kent, 100 380-foot turbines, spanning 22 square miles and representing two years of construction, have begun to power Britain. Bearing a price tag of 780 million pounds, this is the world’s largest offshore wind farm.
China is already the world's largest market for wind power, but it's not stopping with the onshore sites. A 102-megawatt wind farm is slated to hit full power this month in the Yangtze River delta near Shanghai, Technology Review reports. And that's just the beginning, as Chinese officials opened bids on creating three or four more offshore wind power projects that could generate 1,000 megawatts total.
