Source?
Granted, its not a very efficient process, but its still in the plus column, not the negative in terms of energy production.
I wonder if it'd be cheaper if we just fermented the $$$ instead of throwing it at the corn farmers?
"Source?"
Do you actually read the articles & posts???
I already told you on post #6 that the World Bank estimates that Brazil produces ethanol for a buck a gallon!
Now either start reading the articles and the posts or go sober up elsewhere!

"The Energy Balance of Corn Ethanol: An Update", by Hosein Shapouri and James A. Duffield, U.S. Department of Agriculture, Office of Energy Policy and New Uses, and Michael Wang of the Center for Transportation Research, Energy Systems Division, Argonne National Laboratory. Agricultural Economic Report No. 813: "Corn ethanol is energy efficient... For every BTU dedicated to producing ethanol there is a 34% energy gain... Only about 17% of the energy used to produce ethanol comes from liquid fuels, such as gasoline and diesel fuel. For every 1 BTU of liquid fuel used to produce ethanol, there is a 6.34 BTU gain."
