Natural gas is a fossil fuel energy source. Natural gas contains many different compounds. The largest component of natural gas is methane, a compound with one carbon atom and four hydrogen atoms (CH 4 ). Natural gas also contains smaller amounts of natural gas liquids (NGLs, which are also hydrocarbon gas liquids ), and nonhydrocarbon gases ...
