Corn based ethanol has clearly raised the price of food in America. But there is good news on the horizon. Several companies are investing and testing ethanol produced from Jatropha and from algae. There is enough algae to create ethanol without creating any other harmful consequences (at least none that we know of now). Jatropha uses less water, fertalizer and can be grown on fewer acreas of land when compared to corn based ethanol. I see the silver lining. I hope it is true.
