Oil and Gas

Although researchers all over the world are working on the technology to harness the alternate resources of energy like solar, wind, hydropower and nuclear energy, the conventional resources of oil, gas and coal are still the major resources of energy. These resources are fast declining since they are non renewable. Rapid industrialization and urbanization are responsible for this. In addition, these conventional resources add pollutants to the atmosphere.

Presently the positon of energy producers is like this
