Making up over 62% of the state's generated electricity in 2022, wind power is the largest source of electricity generation in Iowa.[1][2] In 2020, over 34 billion kWh of electrical energy was generated by wind power. As of 2022, Iowa has over 12,200 megawatts (MW) of installed capacity with over 6,000 wind turbines, ranking second and third in the nation below Texas respectively.[3]
The development of wind power in Iowa began with a state law, enacted in 1983, requiring investor-owned utilities in the state to purchase 105 MW of power from wind generation.[4] Former governor Terry Branstad stated that by 2020 the percentage of wind generated electricity in Iowa could reach 40 percent. This goal has been exceeded, with over 40 percent of Iowa's electricity being generated from the wind as of October 2019 according to the Energy Information Administration, a first in the nation accomplishment.[5]
