Compared to other hydrocarbon fuels, methane produces less carbon dioxide for each unit of heat released So That's why it is used as a fuel.

the chemical formula CH4 (one atom of carbon and four atoms of hydrogen). It is a group-14 hydrideand the simplest alkane, and is the main constituent of natural gas. The relative abundance of methane on Earth makes it an attractive fuel, though capturing and storing it poses challenges due to its gaseous state under normal conditions for temperature and pressure.Methane is used in industrial chemical processes and may be transported as a refrigerated liquid (liquefied natural gas, or LNG). While leaks from a refrigerated liquid container are initially heavier than air due to the increased density of the cold gas, the gas at ambient temperature is lighter than air. Gas pipelines distribute large amounts of natural gas, of which methane is the principal component.
FuelEdit
Methane is used as a fuel for ovens, homes, water heaters, kilns, automobiles,[22][23]turbines, and other things. Activated carbon is used to store methane. Liquid methane is also used as a rocket fuel when combined with liquid oxygen, as in the BE-4 and Raptorengines.
Natural gasEdit

Methane is important for electricity generation by burning it as a fuel in a gas turbine or steam generator. Compared to other hydrocarbon fuels, methane produces less carbon dioxide for each unit of heat released. At about 891 kJ/mol, methane's heat of combustion is lower than any other hydrocarbon but the ratio of the heat of combustion (891 kJ/mol) to the molecular mass (16.0 g/mol, of which 12.0 g/mol is carbon) shows that methane, being the simplest hydrocarbon, produces more heat per mass unit (55.7 kJ/g) than other complex hydrocarbons. In many cities, methane is piped into homes for domestic heating and cooking. In this context it is usually known as natural gas, which is considered to have an energy content of 39 megajoules per cubic meter, or 1,000 BTU per standard cubic foot.
Methane in the form of compressed natural gas is used as a vehicle fuel and is claimed to be more environmentally friendly than other fossil fuels such as gasoline/petrol and diesel.[23] Research into adsorption methods of methane storage for use as an automotive fuel has been conducted.[24]
