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
natural gas 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....
