Natural Gas 101

From , former About.com Guides

Natural gas can be used as a motor fuel as either compressed natural gas (CNG) or liquefied natural gas (LNG). Cars and light trucks may be ordered from manufacturers to operate on natural gas, and can also be set up as bi-fuel vehicles: to operate on either gasoline or natural gas. A real plus—if natural gas is available where you live, a filling station can be outfitted right in your garage for convenient at home refueling.
