Largest producing U.S. states and companiesBiofuels are a biomass-derived type of alternative motor fuel. They may be used unblended for engines operating on pure biofuels or combined with refined petroleum for usage in regular engines. Different types include biodiesel, bioethanol, and biogas. Crops such as corn, wheat, and soy are among the most common feedstocks used to create these fuels in the United States. Many refineries are located in the Midwest. Iowa houses both the largest U.S. production capacity of ethanol plants and biodiesel plants. The state’s annual biodiesel production amounts to over eight million barrels, the most of any U.S. state.
