According to M. King Hubbert's Hubbert peak theory, Peak gas is the point in time at which the maximum global natural gas (fossil gas) production rate will be reached, after which the rate of production will enter its terminal decline. Natural gas is a fossil fuel formed from plant matter over the course of millions of years. It is a finite resource and thus considered to be a non-renewable energy source.
