Methane is just used as a fuel for a gas turbine (can also be used to drive an internal combustion engine coupled to a generator). The turbine is coupled to a generator, which generates electricity.
During energy generation chemicals such as methane are released into the air as a result of oil and natural gas extraction. The combustion of coal and natural gas for electricity production causes the release of sulphur dioxide, nitrogen oxides and carbon dioxide into the air.
