Energy Sources in India: Overview and Impact

  • 70% of cooking energy in rural areas comes from wood and dung cakes, but deforestation is depleting forests rapidly.
  • Coal is a crucial conventional energy source in India, meeting most energy needs and used in power generation and domestic settings.
  • Coal is classified into Peat, Lignite, Bituminous, and Anthracite based on quality and age, with Anthracite being the highest quality.
  • Coal is further divided into Godwana and Terser types based on age, with Godwana being older and found in regions like West Bengal and Jharkhand.
  • Petroleum is India's second-largest energy source, used in various industries and derived from rocks formed underground.
  • Natural gas, found alongside petroleum deposits, is considered clean energy and used in industries and as CNG and PNG for transport and cooking.
  • Electricity is mainly generated through hydroelectricity and thermal electricity, with hydroelectricity being renewable and utilized in multipurpose projects in India.
  • Non-conventional energy sources like nuclear, solar, wind, biogas, tidal, and geothermal energy are being adopted due to the depletion of fossil fuels and environmental concerns.
  • Nuclear energy is generated by altering atomic structures using elements like uranium and thorium found in specific regions in India.
  • Solar energy, wind power, biogas, tidal energy, and geothermal energy offer renewable and environmentally friendly alternatives to conventional energy sources, with India having significant potential for their utilization.
