We’ve been hearing a lot about the potential of biofuels, particularly ethanol, as being a great (and green) answer to our global dependence of petrochemicals. Which is true, to a certain extent.

Of course, we’ll need to do something about the enticing boondoggle subsidies that are making corn ethanol such an enticing political playing piece first. [Image by Jpeg Jedi]
