> Or... maybe people just use less. 7 percent? Easy. E10 (current standard) == 90-units of gasoline / petroleum. E15 == 85-units, or a 5.6% reduction. That's most of that 7% reduction already handled. E20 == 80-units, or a 12% reduction in gasoline from E10. Done and done. I'm not trying to oversell anything. It just seems like one of the easiest sources of alternative fuel we got. You're right in that more advanced ethanol exists beyond corn, but those advanced refineries only exist in small numbers. Realistically speaking, if we are to ramp-up ethanol production in this country, its gonna be corn. The advanced-biofuels are _almost_ ready, but still something that's a year or two away from mass production. (They're done the "research" phase and we're even making millions-of-gallons of cellulosic ethanol per year... but its not the billions we need quite yet) ------ I'm not trying to "oversell corn", I'm just acknowledging that we can't really rely upon adv. biofuel (ex: Switchgrass ethanol) quite yet. I'm optimistic on that front. But if we're talking about solutions that may exist by the time these Russian sanctions hit our economy (ie: once our domestic strategic oil reserves run out), its looking like Corn is the short-term answer.
