Higher gasoline prices and goals of decreasing U.S. oil dependence have spurred interest in natural gas vehicles (NGVs) for personal use and compressed natural gas as an alternative to conventional fuels. In the light-duty category, there are a growing number of CNG vehicles offered by auto manufacturers. In addition, many late model vehicles have EPA-approved after-market conversion systems available.
Purchasing a pre-owned fleet vehicle is another option, especially in states where natural gas has been used for fleet transportation for several decades. States with the highest natural gas fuel consumption rates are California, New York, Texas, Georgia, Massachusetts and Washington, D.C.
Many states have federal vehicle tax credits as incentives for drivers to purchase or convert a qualifying existing vehicle to a CNG vehicle.
