Main Body

Natural gas is extracted from the refining of petroleum and is less polluting and more energy dense fuel than coal and petroleum. At present 63% of India's energy generation comes from thermal power plant of which 67% is natural gas based plant, it is likely to increase further. Globally, the natural gas is widely used with a vast network of pipeline and the shale gas evolution of USA

* USAGE OF NATURAL GAS * 1. Transportation sector - for cars, trucks, etc. it gives much lower PM 2.5 emissions than diesel or petrol. 2. Energy generation - in gas based power plants. It has a higher calorific value of 9000 kcal/ng than coal (4500 kcal/ng). 3. Fuel - for cooking and household application through a network of pipelines. 4. Fertiliser industry (a) Natural

also find its uses in fertiliser industry for production of meat mineral. * Distribution across globe * (Diagram showing world map with shaded regions) Top major regions of gas reserves: Asia - large reserves, Russia, Arabia, North Africa, Caspian region. It is found in: N America - with vast Appalachian and mid lands. S America - Venezuela region. Natural gas is an important source of energy and India has a spot on coal bed methane and shale gas are proving pivotal
