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.
fuel ethanol were used annually in the United States, and by 2004 usage had risen to over 3.4 billion gallons.
