Ethanol from corn is very debateable if it is energy positive. I believe it is slightly positive. If you generate the heat using coal it can be in effect a coal liquefaction process. If you use natural gas - well - it is gas to liquids.

The above aside it is contributing to food inflation. Here there is opportunity for technology to convert waste products and not food to ethanol.
