Alternative Fuel Vehicle refers to a vehicle that runs on a fuel other than traditional
gasoline or
diesel; any method of powering an engine that does not involve
petroleum. Due to a combination of heavy
taxes on fuel, particularly in
Europe, tightening environmental
laws, particularly in
California, and the possibility of further restrictions on
greenhouse gas emissions, work on alternative power systems for vehicles has become a high priority for governments and vehicle manufacturers around the world.
