Natural gas vehicles are proven technology. There are 10 million NGVs in the world, but only 130,000 in the United States. The NAT GAS Act will help jump-start the NGV industry in America. It will grant tax credits to fleet owners to begin replacing their fleets with NGVs.

Taxis and government vehicles, school and municipal buses, express delivery and utility trucks -- in fact, any fleet that generally goes home to the "barn" each night -- are candidates for moving away from burning imported gasoline or diesel to running on domestic natural gas.

Natural gas is one of the most widely distributed natural resources in the country. Gas lines run up and down nearly every street in every community in America. Heavy-duty and fleet vehicles tend to run the same routes on a regular schedule. Drivers stop at the same places to eat, rest and refuel, so the infrastructure to service those vehicles is a relatively simple issue to solve.
