The Five Most Important Energy Forecasts of 2008

I think the sentence you're interpreting as a WOW factor on V2G technology was more likely a slip of the lip from a tired politician since PHEV's are not net generators of electricity and the whole point of a PHEV is to use excess power from the grid instead of gasoline.

In my view, the V2G concept overlooks the critical fact that when you take a PHEV out of the garage it is no longer connected to the grid. So unless we plan a grid expansion and smart metering to every parking spot in America, the bulk of the plug-ins will remain disconnected from the grid during the hours that other grid demands are highest.
