There are only five wind turbines operating in U.S. waters today. But that will likely soon change, partly because of states with ambitious offshore wind targets.
Massachusetts, for example, is about to pick one of the three bids it got from companies vying to build one of the nation's first commercial-scale offshore wind farms. Equipped with the capacity to generate enough electricity to power as many as 150,000 homes, the turbines located about 20 miles southwest of Martha's Vineyard would be among several big offshore wind projects that could transform the grid.
