Ethanol fuel has a "gasoline gallon equivalency" (GGE) value of 1.5, i.e. to replace the energy of 1 volume of gasoline, 1.5 times the volume of ethanol is needed. [4] [5] Ethanol-blended fuel is widely used in Brazil, the United States, and Europe (see also Ethanol fuel by country). [2]

Summary of the main ethanol blends used around the world in 2013. Several common ethanol fuel mixtures are in use around the world. The use of pure hydrous or anhydrous ethanol in internal combustion engines (ICEs) is only possible if the engines are designed or modified for that purpose, and used only in automobiles, light-duty trucks and motorcycles.
A dish of ethanol aflame. Various alcohols are used as fuel for internal combustion engines.The first four aliphatic alcohols (methanol, ethanol, propanol, and butanol) are of interest as fuels because they can be synthesized chemically or biologically, and they have characteristics which allow them to be used in internal combustion engines.
Until 2005 Brazil was the world's top producer of ethanol fuel when it was surpassed by the United States. Together both countries were responsible in 2011 for 87.1% of the world's ethanol fuel production. [1] In 2009 Brazil produced 27.5 billion liters (7.26 billion U.S. liquid gallons), [13] representing 35.9% of the world's total ethanol ...
By the mid-1980s, over 100 new corn alcohol production plants are built and over a billion US gallons of ethanol for fuel were sold per year. The ethanol program is controversial for several reasons, not the least of which was that the ethanol industry was dominated by one company – Archer Daniels Midland of Peoria, Ill. In 1984, the number ...
the quality of the resulting ethanol compared to the quality of refined gasoline; the energy indirectly consumed (in order to make the ethanol processing plant, etc.). Much of the current academic discussion regarding ethanol currently revolves around issues of system borders. This refers to how complete a picture is drawn for energy inputs.
