According to AWEA, wind power generated a record 6.3% of U.S. electricity in 2017, but the impact is even more pronounced at the state level: Iowa, Kansas, Oklahoma and South Dakota generated over 30% of their electricity using wind.The report says operating wind power capacity grew 9% last year. The installation of 7,017 MW of wind in 2017 brings total U.S. installed wind power capacity to 88,973 MW; that’s just under 54,000 wind turbines operating in 41 states, Guam and Puerto Rico – enough installed capacity to power a record 27 million American homes.
