Natural gas burning on a gas stove Burning of natural gas coming out of the ground. Natural gas (also called fossil gas, methane gas, or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane (95%) [1] in addition to various smaller amounts of other higher alkanes.
As of 2020 whether natural gas should be used as a "bridge" from coal and oil to low carbon energy, is being debated for coal-reliant economies, such as India, China and Germany. [23] Germany, as part of its Energiewende transformation, declares preservation of coal-based power until 2038 but immediate shutdown of nuclear power plants, which ...
The Wobbe index is expressed in MJ/Nm³ (where 'Nm³' indicates'm³ in Normal conditions), or sometimes in BTU/scf.In the case of natural gas (molar mass 17 g/mol), the typical heating value is around 39 MJ/Nm³ (1,050 BTU/scf) and the specific gravity is approximately 0.59, giving a typical Wobbe index of 51 MJ/Nm³ (1,367 BTU/scf).
Natural gas (mostly methane) is an even more potent greenhouse gas when it escapes into the atmosphere prior to being burned. Since the industrial age began circa 1750–1850 with growing wood and coal use, the atmospheric concentration of carbon dioxide and methane have increased about 50% and 150%, respectively, above their relatively stable ...
Carbon dioxide equivalent (CO 2 e or CO 2 eq or CO 2-e) of a quantity of gas is calculated from its GWP. For any gas, it is the mass of CO 2 which would warm the earth as much as the mass of that gas. [34] Thus it provides a common scale for measuring the climate effects of different gases. It is calculated as GWP multiplied by mass of the ...

Countries by natural gas proven reserves (2014), based on data from The World Factbook. Natural gas is a widely available fossil fuel with estimated 850 000 km 3 in recoverable reserves and at least that much more using enhanced methods to release shale gas. Improvements in technology and wide exploration led to a major increase in recoverable ...
