Ethanol is a renewable, domestically produced alcohol fuel made from plant material, such as corn, sugar cane, or grasses. Using ethanol can reduce oil dependence and greenhouse gas (GHG) emissions. Ethanol fuel use in the U.S. has increased dramatically from about 1.7 billion gallons in 2001 to about 14.4 billion in 2016.1.
Corn is also used to make ethanol (for either drinking or as a fuel source for motor vehicles), its by-products and grains as animal feed and biomass for energy, as a source of cooking oil, and for corn syrup and corn starch in the food industry.
