Funny, if I remember right, biofuels were suggested as one of the solutions to peak oil and a dropoff in food production.
You can make biofuel out of wood waste. We're not termites, we don't eat that. But to use oil to grow crops to make fuel to replace oil doesn't seem right.
Food waste, switchgrass, corn husks . . .all of those can be made into ethanol. But I never saw the savings in having to use oil (mostly diesel) to harvest it all. That and increasing our use of potash as fertilizer to produce fuel seems even more of a waste. Nitrogen we can suck out of the air thanks to a smart German chemist, but Potash and Phosphates are even more limited than oil!
Robbing Peter to pay Paul for something that is needed by every living organism! Not smart.
