Currently, Argonne National Laboratory calculates that it takes 740,000 Btu of fossil fuels to make 1 million Btu of energy from ethanol using corn

Badger State Ethanol (BSE) is one of the 97 biomass-feedstock ethanol plants built in the U.S. as of 2006.
Based in Monroe, Wis., BSE has produced ethanol from corn since 2002. BSE痴 plant uses a dry mill process in
which the starch in the corn is hydrolyzed into sugar and then fermented into alcohol. The major steps in the
dry mill process
are: milling, liquefaction, saccharification, fermentation, distillation, dehydration and denaturing.
