Exit up ahead: A University of Minnesota study has concluded that corn-based ethanol is no better than gasoline.
The Star Tribune says ethanol may even be a bigger polluter, when it comes to greenhouse gas emissions and particulate matter. Cellulosic ethanol made from switchgrass and other plant materials is far better for human health, the scientists say.
But the Renewable Fuels Association claims the study is flawed. Among other things, it assumes that grassland will be taken out of the federal Conservation Reserve Program to make more corn-based ethanol. The RFA says most of the increase in corn production in the U.S. has been through higher yields rather than conversion, and there’s no peer-reviewed evidence for the study’s methods. (see the pdf).
