E85

Why are so many delusional environmentalists investing tremendous amounts of money in the development of ethanol-based bio-fuels when refining the corn necessary to make it takes almost the same amount of energy that the weak fuel can produce? Is there any real redeeming quality about this new overhyped "wonder fuel"?

100 gallons of ethanol releases more CO2 than 10 grams of gasoline gj.  CO2 is also released to produce the energy to refine E85.  The question we're concerned about is whether the net effect is helpful or not (ie >>5's final statement).
