Cut out the government subsidies for ethanol and it would disappear almost overnight. It is hideously expensive to make, the land used to raise the corn could be used for useful things like growing food for people or livestock feed. There would be riots in Iowa and the corn belt if the government tit was withdrawn from ethanol. It shortens the life of anything you run it through, costs taxpayers hundreds of millions of dollars if not billions. The only thing green about it is the taxpayers dollars. We are moving from California to Arkansas. Cannot wait to put California in our rear view mirror and move to a Free State.
