What Does
Ethanol Mean?
Ethanol is a renewable energy source derived from plant materials (also known as biomass).
Ethanol is produced by a fermentation process and, as such, is derived from plants that contain the sugars and starches needed to support that fermentation (e.g. sugar cane and corn).
Ethanol is considered an environmentally friendly alternative to fossil fuels since it emits significantly fewer harmful emissions.
Safeopedia Explains Ethanol
Ethanol fuels are often blends of ethanol and gasoline. Most gasoline sold in the United States contains about 10% ethanol.
While the use of ethanol fuels has many environmental benefits, it does contain less energy than a comparable volume of gasoline. This results in lower fuel economy.
