Wind Power

Wind power constituted 25 percent of all US generation capacity additions during 2017. Wind energy contributed 6.3 percent of the nation's electricity supply, more than 10 percent of total electricity generation in 14 states, and more than 30 percent in four of those states (Iowa, Kansas, Oklahoma, and South Dakota).

Lower installed project costs, along with improvements in capacity factors, are enabling aggressive wind power pricing from 7 cents per kWh in 2009 to around 2 cents per kWh during 2017.
