Kurt Cobb points us to an article on Energy Bulletin that suggests ethanol is not everything it’s cracked up to be. By some measurements, it may take as many as 6 units of energy input to yeild one unit of ethanol output, and ironically, most of that input is fossil fuel-based fertilizer. Even if you were to grow corn organically, the amount of land used to produce ethanol would be tremendous and impractical, it is suggested. Energy Bulletin says investments in efficiency would have a far greater payoff in both environmental and financial terms.
