2022 AUG 23

Preliminary   > Geography   >   Resource geography   >   Energy sources' distribution in india

Why in news?

  • ONGC stated drilling its first well at Puga (Ladakh) to generate electricity using geothermal power to reduce the dependence of Ladakh on diesel-run generators.

About Puga:

  • Puga hot spring area, located at the junction of the Indian and Tibetan plates along the Indus Suture Zone, has the greatest potential for the near-term development of geothermal energy in the Indian subcontinent

What is Geothermal Energy?

  • Geothermal energy is heat derived within the sub-surface of the earth.
  • Water and/or steam carry the geothermal energy to the Earth's surface.
  • Depending on its characteristics, geothermal energy can be used for heating and cooling purposes or be harnessed to generate clean electricity.

Potential of Geothermal Power

  • As per the Geological Survey of India, there are around 340 geothermal hot springs in India
  • Ex: Chummathang (Ladakh), Cambay (Gujarat), Khammam (Telangana), Tattapani (Chattisgarh), and Ratnagiri (MH)
  • Though India has been one of the earliest countries to begin geothermal projects way back in the 1970s, but at present, there are no operational geothermal plants in India.
  • The top five countries in terms of geothermal power generation are the US, Philippines, Indonesia, Mexico and New Zealand


Consider the following statements:

1. India’s geothermal energy potential is largely concentrated in northern Indian plains

2. India has the largest number of operational geothermal plants in the world

Which of the statements given above is/are correct?

(a) 1 only

(b) 2 only

(c) Both 1 and 2

(d) Neither 1 nor 2
