Ethanol fuel. The use of ethanol as a fuel for internal combustion engines, either alone or in combination with other fuels, has been given much attention mostly because of its possible environmental and long-term economical advantages over fossil fuel. Ethanol fuel is an alternative to gasoline.
Ethanol Uses. The most common use of manufactured ethanol is as a vehicle fuel for internal-combustion engines. Most gasoline available in the U.S. is blended with 10- to 15-percent ethanol content. Flexible fuel vehicles can run on fuel with a very high ethanol content --- 85 percent ethanol to 15 percent gasoline, for example --- or even on pure ethanol (see References 4). More than 13 billion gallons of ethanol were produced in the U.S. in 2010, and production capacity continues to rise.
