Titled "Ethanol, schmethanol," the article is from the current issue of the Economist and says that everyone is wrong that ethanol will make cars greener. The problem with the piece is that instead of telling us in detail why ethanol doesn't make driving more green; it goes into detail about other fuels like biopetrol and butanol and octanol. Deep, deep detail.
Still, having an article that explains some of ethanol's inherent flaws (less energy than petrol, engine corrosion, water absorption) in comparison to other fuels will be a good resource for those of you who like to point out why ethanol is a terrible idea. If you don't want to read through the piece and just want a quote from the piece that summarizes the story, try this one: "the political rush to back ethanol, just because it is green and people have heard of it, is a mistake."
