Using the PHEV (Plug-In Hybrid Electric Vehicle) to Transition Society Seamlessly and Profitably From Fossil Fuel to 100% Renewable Energy

Green Car Congress

Already Porsche, Mercedes and other high-end automotive manufacturers are making such PHEVs because of the availability of low-cost electricity from wind and solar and the availability of government incentives which make them competitively priced in the beginning. The convenience and low cost of this concept alone merit attention.
