Ethanol from corn is a poor use of resources.  Ethanol from sugar cane is 
much better, but cane only grows in the tropics.

Using corn to feed cows is also a poor use of resources.  It takes 8 kg of 
corn to produce 1 kg of beef, this is not efficient. 
In addition, ruminant livestock produces about 28% of  human-related 
methane.

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.
