In 2005, Congress instituted a new renewable fuel standard. In response, refiners made a wholesale switch, removing methyl tertiary butyl ether (MTBE) and blending fuel with ethanol. Ethanol helps reduce petroleum use and greenhouse gas (GHG) emissions. Derived from corn, ethanol supports U.S. agriculture and helps support energy independence.
