In response to a recent query from an independent student newspaper in the UK, I wrote up an editorial piece on the politics of biofuels. I will post it over here in a few days, but for now it is hosted at their site:
One of the intentions was to point out for European readers why the U.S. and the EU have begun to diverge on their biofuel policies. In the U.S. this is primarily a political issue, because our main biofuel is home grown. In the EU it is mostly imported, so they can take a more objective view.
