Agave, switchgrass, miscanthus, corn stover, forest and ag waste - virtually all plants, trees, bushes, and other flora contain lignocellulose that can be used to make biofuels without touching the food supply chain. Remember the original reason for bioethanol from corn wasn’t based on a fuel shortage, it was aimed at creating demand and thus higher prices for corn.
Just great. How many bobs do we have here? I know about WobblyBob and there may be a WhataboutBob and over in Iraq we left behind BagdadBob. The tequila is getting to me.
I always saw biofuels as less of an energy solution and more of a waste management solution. Getting rid of grease from restaurants is a nasty business.
