Hello, I realize this isn't directly related to transportation planning but this is probably the most appropriate place to post my question.
What's the deal with ethanol?
I've heard that it's much "cleaner" than gasoline (less pollution) but that the production of ethanol consumes more energy than the final product saves.
Is "more energy" in the above sentence fossil fuel energy or some other type of energy?
Someone fill me in. There's a lot of talk about ethanol with the higher gas prices. But a lot of people who I know that are typically for a healthier environment are coming out against ethanol.
