My tdi runs on renewable energy too, it is besides the point here. The question is how do you do a fair comparison of vehicle efficiency when multiple power sources are being compared. Electricity has already gone through the major conversion from it's source, be it sun or coal or whatever, so a straight btu-energy equivalence may over simplify it. In fact I'm not convinced that there IS a good way to compare the two, might as well keep them separate, not letter grades or mpge dumbing down.
