Are We at the Bottom of the Ethanol Barrel?

The fuel gain of corn based ethanol is so marginal, that i wonder if more fuel is being used for transportation to keep the operation of an ethanol refinery running than the refinery actually produces fuel.The current total output of ethanol can only provide a tiny fraction of fuel needs and for that uses loads of corn, vast percentage's of production. And this is a subsidized sector, and hardly turns a profit.
Brazil, one of the leading ethanol producers, sees the percentage of replaced fuels by ethanol at a measle 5% in 2020 ... if they can reach it.
