The report finds that in 2011, roughly 6,800 megawatts (MW) of new wind power capacity was added to the U.S. grid, a 31 percent increase from 2010 installations. The United States’ wind power capacity reached 47,000 MW by the end of 2011 and has since grown to 50,000 MW, enough electricity to power 13 million homes annually or as many as in Nevada, Colorado, Wisconsin, Virginia, Alabama, and Connecticut combined. The country’s cumulative installed wind energy capacity grew 16 percent from 2010, and has increased more than18-fold since 2000. The report also finds that six states now meet more than 10 percent of their total electricity needs with wind power.
