The wind industry made major gains last year, especially in Texas, Iowa and South Dakota, according to a trio of recent DOE reports that found notable growth in the nation's installed wind energy capacity. More than 8,200 MW of wind energy capacity were added last year, representing 27% of all energy capacity added in 2016. Wind now supplies roughly 6% of electricity in the U.S., and 14 states obtain more than 10% of their energy from wind. U.S. wind installations generated more than 226 million MW last year, nearly double the 120 mil-lion MW produced in 2011.
