Iowa, South Dakota, Kansas, Oklahoma and North Dakota all sourced more than 20 percent of their electricity generation from wind power during 2016, according to new data from the U.S. Energy Information Administration (EIA). It shows wind supplied over 5.5 percent of electricity nationwide, up from 4.7 percent in 2015. 
With 99 percent of wind turbines located in rural areas, wind power's steady growth as a share of the nation's electricity supply has been accompanied by a surge of investment in rural America. The industry invested over $13.8 billion in new turbines last year, according to the American Wind Energy Association (AWEA), in addition to operating a fleet now over 52,000 turbines.   Full AWEA Press Release:
