The planned Cape Wind project would put 130 wind turbines in Nantucket Sound, four to 11 miles off the Massachusetts coast. It would be America's first offshore wind farm and it would be a big one. The numbers from a new report on the project are impressive:
The turbines would supply about 10 percent of the 2013 power demand in Southeastern Massachusetts and about 1 percent of the total 2013 New England demand.The project would save the New England region about $185 million a year, according to the report, which was prepared this month by Charles River Associates and commissioned by backers of the project. Over 25 years, this would amount to $4.6 billion.
Part of the reason this wind farm would do so well is that Nantucket Sound happens to be an outstanding place for turbines (it's officially "outstanding," in fact-see below):
