If you think the prius is a farce, you should check out the truth about bio-diesel and ethanol...
They have a negative net energy balance when you take into account refining, production, fertilizer and other energy inputs. The positive energy balances I have seen reported places only 'non-domestic' petroluem on the negative side of the energy balance sheet. By disregarding natural gas and domestic sourced coal burned for electricity and heat production during refining the balance is a net positive. Not quit a fair assessment. But if you want to demonstrate that petroleum imports can be reduced, I guess it is resonable... just not factual. Plus, to make a dent in oil imports, we would have to plant corn or soy on just about every square inch of the country.
