U.S.-based wind power added significantly more new electricity than any other resource in 2014, according to U.S. Department of Energy (DOE) data.
Wind power generated 4% of all the electricity in the U.S. in 2014 and maintained its position as the fifth-largest electricity source in the U.S., according to the latest data from the DOE's Energy Information Administration.
According to data compiled by the American Wind Energy Association, Iowa led U.S. states by producing nearly 29% of its electricity from wind power, followed by South Dakota at 25% and Kansas at 22%. Wind energy provided more than 15% of electricity in a total of seven states.
All renewable energy sources, including hydropower, now deliver more than 13% of the nation's electricity, with wind energy providing more than one-third of that total
