Even some of the Greenies are realizing that Ethanol is a bad idea. Uses way more water than other crops, huge energy input to turn it into fuel, and IIRC after all of the processing along the way the CO2 released is a net increase compared to gasoline.
Added to the suck of government subsidies (our tax dollars) and the cost of production, ethanol also gives reduced mileage, aggressively attracts water, which leads to poor driveability and other issues. Ethanol is also corrosive to some metals and rubber. All add to costs which come right out of our pocketbooks. The farmers are growing a menace.
