Natural gas is an odorless, gaseous mixture of hydrocarbons—predominantly made up of methane (CH4). It accounts for about 30% of the energy used in the United States. About 40% of the fuel goes to electric power production and the remaining is split between residential and commercial uses, such as heating and cooking, and industrial uses. Although natural gas is a proven, reliable alternative fuel that has long been used to power natural gas vehicles, only about two-tenths of 1% is used for transportation fuel.

Less Expensive

The rising cost of gasoline and diesel is making CNG a more attractive alternative fuel. Because CNG is a clean-burning fuel, resulting in minimal engine wear, NGV owners also benefit from lower operating costs due to reduced engine maintenance requirements. Since CNG does not contaminate and dilute the crankcase oil, intervals between oil changes for NGVs are greatly drawn-out, depending on how the vehicle is used.

Better for the Environment

CNG burns much cleaner than gasoline and diesel. According to the Environmental Protection Agency, CNG can reduce carbon-monoxide emissions by 90% to 97% and nitrogen-oxide emissions by 35% to 60% when compared with gasoline. CNG can also potentially reduce non-methane hydrocarbon emissions by 50% to 75%, while producing fewer carcinogenic pollutants and little or no particulate matter.


As proven by government and independent tests, CNG is safer than gasoline and diesel. CNG storage tanks are stronger and safer than gasoline or diesel fuel tanks reducing the likelihood of an accidental fuel release. If released, natural gas is lighter than air and will dissipate quickly into the atmosphere instead of forming pools on the ground. Due to its narrow flammability range, natural gas will not burn in air concentrations that are below 5% and above 15%. Finally, natural gas is non-toxic and non-corrosive and does not pose a risk of water or ground contamination.

National Energy Independence

 Every day the United States spends millions of dollars to buy oil from foreign countries. These dollars going out of the United States add to our trade deficit and weaken our economy. About 98% of the natural gas we use comes from North America. Every gallon equivalent of natural gas used in vehicles is one less gallon of petroleum that must be imported. By using domestic natural gas, we strengthen both our nation’s economy and energy security -- keeping jobs and our money at home.
