Ethanol is an alcohol made by fermenting the sugar and starch components of crops including wheat, corn, sugar cane and other feedstocks. Ethanol can be produced using enzyme digestions, fermentation, and distillation and is the most commonly utilized biofuel in the world, especially in Brazil and the United States. Nearly all of U.S. gasoline contains ethanol in a low-level blend to meet the renewable standard requirements under the Clean Air Act. Ethanol is also increasingly available in E85, an alternative fuel that can be used in flexible fuel vehicles.
