Alternative fuel sources and America

If you don't believe that oil companies are doing all they can to reduce the percieved viability of alternate fuel sources, you are an extreme optimist or a moron.

I was hoping for a more intellectual debate on it, and editing in a fourth question.

We're not going to be able to tap the same supplies of material for food and fuel. We need to use algae to produce the ethanol (if that is shown to be feasible).
