Profile Overview

Quick Facts

  • Iowa is the nation's largest fuel ethanol and biodiesel producer, accounting for one-fourth of U.S. fuel ethanol production capacity and one-fifth of biodiesel manufacturing capacity.
  • Iowa's nearly 5,100 wind turbines generated 42% of the state's electricity in 2019, the highest wind power share for any state.
  • In 2019, wind turbines generated more electricity in Iowa than coal-fired power plants for the first time, as coal's share of net generation in the state declined by more than half over the past decade to 35%.
  • Iowa is the only non-crude oil-producing state among the top 5 energy-consuming states on a per capita basis, due to Iowa's relatively small population along with its energy-intensive manufacturing and agricultural sectors. 
  • In 2018, Iowa was the fourth-largest consumer of hydrocarbon gas liquids, mostly propane--which is used for drying the state's large harvested corn crop and for heating one in eight Iowa households.
