Coal is the most abundant fossil fuel, but natural gas has been called nearly the perfect energy source. From all fossil fuel , natural gas (which is mainly known as methane) has the least impact on the environment. It burns cleanly. The chemical product of burn methane is carbon dioxide and water vapour, which are not pollutant, although they are green house gases.
Like oil, natural gas flows easily and cheaply by pipelines, unlike oil, gas does not move as freely in international trade by sea. Liquid natural gas (LNG) is extremely hazardous, because the mixture of methane and air is explosive. Natural gas is also non-renewable; its supply is finite. Worldwide just two regions contain two third of the proved gas reserves: Russia and the Middle East. The remaining is divided equally among North America, Western Europe, Africa and Asia, each of which contains 4% to 8% of the total.
Most gas is used directly for industrial and residential heating. in fact ,gas has been overtaken both coal and oil as a house-heating fuel and more then half of the homes in the united states are now heated by gas .a portion is also used in electricity –generating plants.
