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.
The use of ethanol for fuel was widespread in Europe and the United States until the early 1900s (Illinois Corn Growersâ Association/Illinois Corn Marketing Board). Because it became more expensive to produce than petroleum-based fuel, especially after World War II, ethanolâs potential was largely ignored until the Arab oil embargo of the 1970s.
