I saw a big sign in front of the BP in Marathon today advertising E85 ethanol. First one I've seen in this area. Went for $2.65 a gallon today, whereas the regular stuff went for $3.07/3.17/3.27/D 3.12.
I know corn-based ethanol isn't the be-all end-all, as production isn't all that efficient, and widespread usage could cause a whole new set of problems with prices and shortages, but hopefully other forms of ethanol will catch on and help us alleviate our dependence on foreign oil.
Personally, I think we should ban tobacco and allow tobacco farmers to replace their crops with industrial hemp, which, incidentally, counts ethanol as one of its myriad uses.
