Corn Ethanol Controversy!
Ethanol (CH3CH2OH) is a clear, colorless liquid. It is also known as ethyl alcohol, EtOH, and grain alcohol. Ethanol is widely produced by processing grains such as corn or starch and sugar crops. The grain is first milled, then fermented with yeast and different enzymes to turn the grain 's starches into alcohol(EPA). A distillation process then increases the ethanol concentrations, basically the same process a whiskey maker would use to make whiskey. Of course, law mandates that a denaturant is added, making the liquid unsafe for drinking. In the process, waste grain is produced and sold as farm animal feed. Bioethanol, can be made from many types of trees and grasses, but the procedure is much harder. The chemical formula of ethanol is the same whether it is made from starch and sugar-based feedstocks, such as corn grain (widely used in United States), sugar cane (Brazil), or from cellulosic feedstocks (such as wood chips or crop residues).

In the United States, ethanol is primarily used as a blending element in the production of gas and as an alternative fuel. More than 95% of the gasoline sold in the United States contains ethanol. Most of ethanol blending into U.S. motor gasoline occurs to meet the requirements of the 1990 Clean Air Act (RFG Fuel) and the Renewable Fuel Standard set forth in the Energy Independence and Security Act of 2007.
