I have to disagree. Illinois adds 15% ethanol to it's gas, and we've been running on it for years with no problems. It's cheap, it's renewable, and it helps corn farmers get rid of excess product.
If ethanol is cheaper, then why is it necessary that Congress mandates it's use? Are they smarter than the rest of us, or something. Does Congress know more about the Oil Bidness than all those fellas in the Oil Bidness?
If it just was a substitute for lead in gasoline it would be okay, and if it was really just a way to use up "surplus" corn, other than making burbom of course it would be okay.
But corn is being grown to make ethanol, and the process is a net energy loser. The farmers get subsidies for growing and selling the corn, and make big contributions with some of the money and the contributions go to the politicians who back the use of ethanol. Because of this, ethanol IS a PORK project.
