Ethanol is the biggest joke.....we need to scrap it and find something else. Why should we pay farmers to grow the corn, pay ethanol plants to make the ethanol, and then pay for the gas in our cars? It costs $10 a gallon to make but sells for $4? And on top of all that, food costs rise, because all the corn is used for ethanol. It's ridiculous, and it's not an answer to anything.
