ive heard they can make ethanol out of different grasses, which dont drain all the nutrients out of the soil like corn, dont need to be replanted each year like corn, and dont require massive fertilization and pesticides like corn. but then the seed/pesticide/fertilizer companies wouldnt make money, so it isnt as popular as it should be.
