Compared to their gasoline- and diesel-powered counterparts, NGVs offer a number of benefits:
- Reduced maintenance costs. Because natural gas burns cleaner than gasoline, NGVs can go longer between oil changes and engine tune-ups.
- Reduced fuel costs. An equivalent gallon of natural gas costs, on average, about one-third less than conventional gasoline or diesel at the pump. It also costs less than other fuels, including ethanol, methanol and propane.
- Less wear and tear on vehicles. Natural gas does not react to metals the same way gasoline does. The pipes and mufflers on NGVs last longer. NGVs also experience less knocking, no vapor locking, and start up and drive more smoothly.
- Reduced impact on the environment. Natural gas is a clean-burning fuel for vehicles. On average, the carbon footprint for an NGV will be 25 to 28 percent less than its gasoline- or diesel-powered equivalent. According to the U.S. Environmental Protection Agency, NGVs:
- Reduce carbon-monoxide emissions 90 to 97 percent.
- Reduce carbon-dioxide emissions 25 percent.
- Reduce nitrogen-oxide emissions 35 to 60 percent.
- Potentially reduce non-methane hydrocarbon emissions 50 to 75 percent.
- Emit fewer toxic and carcinogenic pollutants.
- Emit little or no particulate matter.
- Eliminate evaporative emissions.
- Reduced dependence on imported oil and increased energy security. NGVs are fueled by a natural resource that the United States has in abundant supply. About 86 percent of the natural gas currently used in the U.S. is supplied by domestic sources. Most of the remaining usage is supplied by Canada. At the same time, natural gas reserves in the U.S. have been increasing as new drilling technologies make it possible to tap into unconventional sources. It’s now estimated that domestic supplies are sufficient to meet U.S. natural gas demand for more than 100 years. This ample supply makes it possible for us to increase the use of natural gas and reduce our dependence on foreign sources of energy and imported oil.
- Easy to refuel and safe to drive. NGVs are as easy to refuel as other vehicles, and actually safer to operate.
