Obama on the Environment

Do you have a source for this claim? I'm no expert, but the October '07 National Geographic provides a fantastic article on biofuels and, though I agree that many of these fuels are not the answer, the article shows a production/output energy ratio for corn ethanol at 1/1.3 and Biodiesel at 1/2.5 Neither is ideal, but they both require less energy to produce than they return. The savings in greenhouse gas emissions, too, are significant compared to convential gas and diesel... Nuclear = Yuck :)
