Cassman recently published a paper on "Improvements in Life Cycle Energy Efficiency and Greenhouse Gas Emissions of Corn Ethanol." We'll need those ethanol ameliorations--the 2007 Renewable Fuels Standard calls for 36 billion gallons of biofuel by 2022, with much of that coming from Nebraska's bountiful cornfields.
In etho-politics, the Benator (a.k.a. U.S. Sentor Ben Nelson) joined several other corn-belt legislators, introducing biofuel legisltaion with two primary prongs, a) to increase the minimum blend from E10 to E15 (fuel enriched with 15 % ethanol instead of 10 %) and to limit the EPA from penalizing domestic ethanol producers for environmentally-damaging land use.
