Actually, that is a myth as well. The "research" that supposedly proved that ethanol consumes more energy that it produces has been debunked a number of times.
No, it has not. Nobody has yet been able to conclusively prove that studies that arrive at similar outcomes to the Pimentel study at Cornell are not accurate--unless you assume incredible decreases in the actual energy inputs needed to grow and harvest corn.
That said, producing ethanol from corn is very inefficient. Ethanol from sugar would be price competitive with gasoline if we got rid of all the sugar price supports.
The same process repeats itself eventually with sugarcane (as the Brazillians are finding out). In order to produce enough of it to make any decent amount of ethanol, you ultimately kill the ground by robbing it of both carbon and other nutrients.
