Ethanol produced from agricultural crops is most correctly referred to as Bio-Ethanol, and it is obtained from the fermentation of sugar found in the various feedstocks (raw materials). Ethanol can be produced from a variety of feedstocks including, but not limited to, corn, sugar cane, and sorghum. Using ethanol is one of the best available ways to fight air pollution from vehicles because it contains 35% oxygen; and adding oxygen to fuel results in more complete fuel combustion, thus reducing harmful tailpipe emissions. Ethanol also displaces the use of toxic gasoline components such as benzene, a carcinogen. Ethanol is non-toxic, water soluble and quickly biodegradable. With regard to the "Greenhouse Effect," the ethanol production process represents a carbon cycle, where plants absorb carbon dioxide during growth, "recycling" the carbon released during fuel combustion. The use of 10% ethanol blends reduces greenhouse gas emissions by 12-19% compared with conventional gasoline, according to Argonne National Laboratory. In 2005, ethanol use in the U.S. reduced C02-equivalent greenhouse gas emissions by approximately 7.8 million tons, equal to removing the annual emissions of more than 1.18 million cars from the road (Source: Renewable Fuels Association www.ethanolrfa.org)
