Some good answers here, led me to do some more research
About 1/3 of the US corn crop goes towards livestock feed.
13% is exported.
40% is used for ethanol production
That leaves 14% for food and beverage (including oils, syrups, sugars)
Ethanol is being used in some cases to replace MTBE, to increase octane rating. Why? Because of it's resistance to ignition. This is very tiny percentage of the gasoline blend. E10 and E85 are ethanol as an attempt to replace fossil fuels. However, that resistance to ignition, when used at 10% or 86% is what makes it an inefficient fuel, increasing consumption by 3% or 25% respectively. It takes one unit of fossil fuel to generate 1.3 units of (less efficient) ethanol fuel.
Since 1980, the ethanol industry has received $45B in government subsidies.
The windmills don't seem so bad anymore.
