Ehhh, I'm actually kind of bearish on grains as bio-fuel. I'd like to see the switchgrass biofuel take off. A surprising amount of emissions in the USA (and Brazil) are due to deforestation associated with turning forests into farmland. That's largely mitigated by using "natural plants", like switchgrass instead of farm crops. I mean, its all "solar power into fuel", which is great. But its also important to recognize that some (ie: switchgrass based biofuel) are better than others (ex: grain or corn based biofuel).
