In 2006 we imported 3.5 Billion liters (925 Million Gallons) of ethanol from Brazil. They do more than want to; they export more to us than anywhere else.
It's all to protect a few votes in the midwest. If we are going to do this, you have to jump in with both feet. Right now, this morning, refined sugar is about 10 cents a pound. At 10 pounds per gallon of ethanol, thats $1 a gallon with a refined product. You don't need to refine it before fermentation, but that just shows how cheap it can be if we weren't propping up the corn farmers. In Brazil, ethanol is 1/2 the price of gasoline and they export a surplus.
