A plug-in hybrid electric vehicle (PHEV) is a full hybrid, able to run in electric-only mode, with larger batteries and the ability to recharge from the electric power grid. They are also called gas-optional, or griddable hybrids. Their main benefit is that they can be gasoline-independent for daily commuting, but also have the extended range of a hybrid for long trips. They can also be multi-fuel, with the electric power supplemented by diesel, biodiesel, or hydrogen. The Electric Power Research Institute's research indicates a lower total cost of ownership for PHEVs due to reduced service costs and gradually improving batteries. The "well-to-wheel" efficiency and emissions of PHEVs compared to gasoline hybrids depends on the energy sources of the grid (the US grid is 50% coal; California's grid is primarily natural gas, hydroelectric power, and wind power). Particular interest in PHEVs is in California where a "million solar homes" initiative is under way, and global warming legislation has been enacted
Did you know:
If you bought a hybrid vehicle in 2004 or 2005, you can claim a $2,000 one-time deduction on your 2004 or 2005 tax returns. The deduction is scheduled to drop to $500 in 2006, buy may be resurrected if/when a new energy bill is passed.

The gas-electric hybrid uses less gasoline than conventional internal combustion engines and does not have the limitations in range that have been a problem for traditional electric vehicles. This type of piston engine is used in hybrid electric vehicles which have begun to enter the market as of 2002.
The number of hybrid vehicles available to consumers continues to grow as Ford Motor Company offers the first commercially available hybrid SUV, the Escape Hybrid, for model year 2005. Toyota Motor Corporation will also be offering hybrid versions of the Toyota Highlander and Lexus RX400 SUVs for model year 2005. Honda will be offering a hybrid version of the Accord for this model year, further increasing consumer choices for hybrid vehicles.
Regenerative Braking. The electric motor applies resistance to the drivetrain causing the wheels to slow down. In return, the energy from the wheels turns the motor, which functions as a generator, converting energy normally wasted during coasting and braking into electricity, which is stored in a battery until needed by the electric motor.
Some people have been researching scooters as a way to cope with the gas price increases:
