Using corn and distillation is the most expensive way to produce ethanol, and there's not near enough farmland to sustain the USA for any length of time. Thanks to the miracles of organic chemistry, ethanol can be made much less expensively using other sources, such as natural gas. BUT, natural gas production is already close to being maxed out, is hard to transport, (we would have to supply pretty much all the gas ourselves) ....so it doesn't look so good. The drastic increases in NG prices lately would support this. (ours went up by 47% just this year)
In addition, the following was cut and pasted from this address... (and this site is rather 'optimistic')
http://www.eap.mcgill.ca/MagRack/SF/Winter%2091%20M.htm
Based on the high yielding 1988 corn crop of 119 bushels/ acre the energy generated by the ethanol exceeded energy inputs by 16%. However H appears we still have a long way to go to enable this technology to supply our North American oil addiction. In 1989, 400 million bushels of corn in the U.S were used for ethanol production which produced the equivalent energy of 21 million barrels of oil. The U.S uses about 16.5 million barrels of oil per day.
Therefore, the 3.5 million acres of corn would provide America with approximately 30 hours of oil.
Another site (not very positive) indicated 97% of our land would have to be planted with corn, and the cost of production is way more than what we get out of the ethanol.
