The Energy Department has released three wind market reports demonstrating continued growth in wind energy nationwide.

America’s wind industry added more than 8,200 megawatts (MW) of capacity last year, representing 27 percent of all energy capacity additions in 2016.

In 2016, wind supplied about 6 percent of U.S. electricity, and 14 states now get more than 10 percent of their electricity from wind.

The reports cover the following market sectors: land-based utility scale, offshore, and distributed wind.

Iowa led the nation in the percentage of in-state generation of electricity from wind; wind energy accounts for more than a third (36.6%) of Iowa’s electricity.

Iowa ranks 2nd nationwide (behind only Texas) in cumulative installed capacity with 6,911 MW of utility-scale wind turbines.

Iowa ranked 3rd nationwide (behind only Texas and Oklahoma) in annual installed capacity for 2016 with 707 MW of utility-scale wind energy.

Iowa leads the nation in small wind turbine installations, with 9.45 MW of small wind installed between 2003 and 2016.

For overall distributed wind capacity (including both small and large turbines deployed in distributed applications), Iowa ranks 3rd nationwide (behind only Texas and Minnesota), with 129.2 MW installed since 2003.

Wind power capacity in the United States experienced strong growth in 2016.

Recent and projected near-term growth is supported by the industry’s primary federal incentive—the production tax credit (PTC)—as well as myriad state-level policies.

Wind additions have also been driven by improvements in the cost and performance of wind power technologies, yielding low power sales prices for utility, corporate, and other purchasers.

“The wind industry continues to install significant amounts of new capacity, and supplied about 6 percent of total U.S. electricity in 2016,” said Acting Assistant Secretary for Energy Efficiency and Renewable Energy Daniel Simmons. “As our reports explain, a combination of federal subsidies, state mandates, and technological advancements continue to help drive new wind capacity additions.”
