Profile Overview

Quick Facts

  • Iowa is the nation's largest fuel ethanol and biodiesel producer, and accounts for one-fourth of U.S. fuel ethanol and one-fifth of biodiesel production capacity.
  • In 2020, wind turbines generated 57% of Iowa's electricity, the highest wind power share for any state.
  • Iowa ranks in the top 10 states in electricity sales per capita, and about one in four Iowa households rely on electricity for home heating.
  • Iowa is the only non-crude oil-producing state among the top 5 energy-consuming states on a per capita basis, mainly because of Iowa's relatively small population and its energy-intensive industrial sector. 
  • Iowa is 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.
