Of the fossil fuels, natural gas is the cleanest source of energy to use for many of our every day needs and activities. It plays an important part in reducing pollution so that a clean and healthy environment can be maintained. Because of its almost perfect combustion process, very few byproducts are emitted into the atmosphere as pollutants. The environmentally friendly attributes of natural gas reduce air pollution.
Composed primarily of methane, the main products of the combustion of [tag]natural gas[/tag] are carbon dioxide and water vapor which are the same compounds we exhale when we breathe. Unlike other fossil fuels, the combustion of natural gas releases very small amounts of sulfur dioxide and nitrogen oxides, virtually no ash or particulate matter, and low levels of carbon dioxide, carbon monoxide, and other reactive hydrocarbons.
Transportation vehicles such as automobiles, trucks, and buses contribute greatly to the air pollution in the United States. This kind of air pollution makes for low visibility, smog, and various greenhouse gas emissions. According to the Department of Energy (DOE), more than 80 percent of air pollution in cities is produced by transportation vehicles. Natural gas can be used to cut down on these high levels of pollution from gasoline and diesel powered cars, trucks, and buses.
According to the EPA, vehicles operating on compressed natural gas have reductions in carbon monoxide emissions of up to 97 percent and reductions in carbon dioxide emissions of 25 percent. Nitrogen oxide emissions, and other non-methane hydrocarbon emissions could all be reduced drastically. Because of the relatively simple makeup of natural gas, there are fewer toxic and carcinogenic emissions from vehicles running on natural gas.
