context_page_description: According to M. King Hubbert's Hubbert peak theory, peak gas is the point in time at which the maximum global natural 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.
  The concept of peak gas follows from Hubbert peak theory, which is most commonly associated with peak oil. Hubbert saw gas, coal and oil as natural resources, each of which would peak in production and eventually run out for a region, a country, or the world. Since Hubbert's initial predictions in 1956, "the proper application of ever more powerful statistical techniques has reduced much of the uncertainty about the supply of oil and natural gas". One view in 1997 was that Hubbert's use of an exponential decline model was statistically adequate in explaining real world data. However, longer-term experience has shown the predictions to be incorrect.
