The U.S. wind energy industry installed 1,389 megawatts in the third quarter, bringing to 4,204 MW the total of wind power projects completed in what is expected to be another record year, according to the American Wind Energy Association (PDF).

With even more reported under construction, the industry is on track to surpass 2007, when 5,249 MW were installed, with a total of about 7,500 MW this year (7,500 MW would generate enough electricity to power the equivalent of about 2.2 million homes).
