President Bush made a big push for alternative fuels in his State of the Union speech Tuesday night, calling on Americans to reduce gasoline consumption by 20% over 10 years. And as soon as the sun rose on Wednesday, he set out to tour a DuPont facility in Delaware to tout the virtues of “cellulosic ethanol” and propose $2 billion in loans to promote the stuff. For a man who famously hasn’t taken a drink for 20 years, that’s a considerable intake of alcohol.
A bit of sobriety would go a long way in discussing this moonshine of the energy world, however. Cellulosic ethanol–which is derived from plants like switchgrass–will require a big technological breakthrough to have any impact on the fuel supply. That leaves corn- and sugar-based ethanol, which have been around long enough to understand their significant limitations. What we have here is a classic political stampede rooted more in hope and self-interest than science or logic.
