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

Green Car Congress

The alternative-fuel car evolved to reduce exhaust emissions and other problems derived from burning fossil fuels. Globally, billions of people are using this ancient grid as installed, but the enormous potential of the grid is untapped—we could be getting much more energy from it. by Professor Andrew Alfonso Frank.
