Ethanol efficiency concession
I guess blogs are intended to allow us to drag out discussions forever, so I'll kick the sleeping dog and add another caveat to the point I made a few months ago (that point being the limit to the amount of arable land and agricultural effort we can afford to put into biofuel feedstock production)
Today's news included an article on the mileage efficiency concession (relative to gasoline) that seems to come along with ethanol use.
E85 (85% ethanol and 15% gasoline) use in flexible fuel vehicles seems to result in as much as 25% decline in mileage efficiency. This effect is admitted by GM, which is hitching its wagon to flex fuel vehicles.
