he's estimating the energetic i.e. objective cost. If the government subsidized to the point of us stopping pumping up oil or true fossil neutral rate (ignoring the CO2 already up there, which will over hundreds of years fall back to natural levels), then we would have to manufacture our fuels... with what energy? sure in the long term I think we can use renewable, but it isn't deployed yet. The only way this makes sense is if we deploy true renewable energy, and stop allowing fossil fuel industry to masquerade as green.
