The US added about 3,600 megawatts of wind power capacity in the first nine months of 2015, almost triple the amount from a year earlier, as businesses and local governments moved to line up their own supplies of electricity.
Thirteen wind farms accounted for 3,596 megawatts installed through September, up from 1,254 megawatts a year earlier, according to a report Thursday from the American Wind Energy Association. The 1,602 megawatts added from July through September were almost four times the total in last year’s third quarter, the Washington-based trade group said.
