Plug-In Hybrid Cars Provide Alternative

A standard hybrid car has an electric engine powered by batteries and an optimized on-board gasoline engine. The only source of electricity for charging the batteries is the gasoline engine. In a plug-in hybrid vehicle, an additional source for electricity for charging the batteries may be an AC wall plug while the vehicle is parked in the owner's garage, or a solar panel on the roof.

The government will be cool to plug-in hybrid cars because the current highway financing scheme is based on gasoline taxes. Additional energy paths for charging the batteries of a hybrid car bypass the gasoline tax.

Nevertheless, automobile manufacturers should be encouraged to add equipment allowing the use of additional electricity sources in hybrid cars.
