Ethanol is an alcohol produced from starch and sugar crops. Ethanol is made from corn, sorghum, potatoes, wheat, sugar cane - even from biomass such as cornstalks and vegetable waste. Ethanol is a renewable fuel made from products that we can grow year after year. This is in stark contrast to other fuels which are derived from non-renewable resources.
Ethanol is made from corn, sorghum and other renewable resources.
How ethanol keeps the air cleaner. By helping the components of gasoline burn more completely, ethanol helps reduce harmful tailpipe emissions such as carbon monoxide and hydrocarbons. Additionally, ethanol is a natural source of octane which replaces harmful chemicals typically used to increase octane. Even the way ethanol is manufactured helps keep the air cleaner. The production and use of ethanol from renewable crops adds no additional carbon dioxide to the atmosphere.
