Natural gas is created by mixing intense heat and pressure with the bodies of plants and animals, or plankton, that have been in the ground for hundreds or millions of years. Natural gas can be both wet or dry. It can be used for heating, cooking, electrical generation, transportation and more.

According to the U.S. Energy Information Administration (EIA), all natural gas used in the U.S. is created in the U.S., reducing our dependence on fuels from other countries. Natural gas can also be a cleaner alternative. When natural gas is burned, it creates fewer pollutants than the burning of coal or petroleum for equal amounts of energy. Natural gas is primarily a nonrenewable resource, but can be renewable when produced using decomposed organic materials to make biogas.

These gasses can be collected from wastewater treatment plants, landfills or farms and will prevent the release of methane into the air. To upgrade biogas to renewable natural gas (RNG), the methane content is increased by removing water vapor, carbon dioxide, hydrogen sulfide and other impurities. RNG is a pipeline-quality gas that is fully interchangeable with conventional natural gas and thus can be used in natural gas appliances and vehicles.
