Sure, you might be able to describe the difference between cellulosic ethanol made by Coskata and that made by Mascoma. Or, perhaps your biofuel knowledge is just right to explain how cellulosic ethanol and corn ethanol are different, and what each might mean to the environment. But trust me, the general public has a long way to go to understand what all these new fuel types are. Remember the posts about filling up with the wrong fuel?
Anyway, I'd just like to point out this letter to the editor that appeared in today's Washington Post. In a May 3 editorial called " The Greening of Montgomery," the WaPo mangled the difference between biodiesel and ethanol, suggesting that while switching Montgomery County's fleet of diesel cars to biofuels would be a good move, because of the problems with ethanol, care should be taken. A reader, Lynne Tucker of Bethesda, wrote in to clarify just which biofuel can go into what type of engine. What we can learn from this is that, as we educate ourselves the latest and greatest green car news, there's a lot we need to do to educate others.
