Chanel, If one does the math on ethanol versus gasoline in motor vehicles one rapidly finds there is only a very small decrease in CO2 emissions and a significant increase in water vapor emissions (which is a much more potent but relatively short lived GHG). When one considers the energy consumed to grown corn or other feedstocks for ethanol fuel, the decrease in CO2 emissions disappears. When one considers the destruction of trees in areas that would normally be considered non-cultivatible without the federal subsidies paid for by our taxes, then that just aggravates the situation because Nature's CO2 recycling devices are being destroyed.

One must also consider we cannot grow enough biofuel feedstock to significantly impact fossil-fuel consumption, especially when that feedstock needs processing that consumes a considerable amount of energy itself.

To significantly impact energy security we need to explore our own resuources, develop more nuclear, and increase the efficiency with which we utilized our energy. Just think about all the energy we bury in landfills, for instance. I do not disagree with processing manure for fuel--it is a waste. I do object to processing food stuffs for fuel, especially since it raises the price of those food stuffs. Heck, the Feds do not include the costs of food and fuel in their inflation calculations--why do you think they don't?
