As it currently stands, we actually use MORE ENERGY (in terms of BTUs) of FOSSIL FUEL in the planting/fertilizing/growing/harvesting/drying process of agriculture of corn for fuel than it produces. It's a negative sum game, and only financially feasible due to the subsidy the federal government pays to the farmer for growing it. If the conversion of biomass to ethanol ever becomes economically feasible, then maybe I can accept the rationale behind using ethanol as a fuel. Until then, it's nothing more than a political lie about "sustainability" being fed to the consumer. And it fucks up my carbs and plastic tanks and other fuel components.
