Conventional and Non Conventional Sources of Energy Part 1

Conventional and Non Conventional Sources of Energy

Different sources of energy are majorly categorised into two sources:

  • Conventional sources of energy
  • Non-conventional sources of energy

ऊर्जा के पारंपरिक तथा गैर पारंपरिक स्रोत भाग 1 

Conventional sources of energy

  • Conventional sources of energy are the natural sources of energy available for a limited time period.
  • These sources are the non-renewable sources of energy and they get depleted with time.
  • They are usually obtained from decaying material which was formed over millions of years ago.
  • Examples of conventional sources of energy: coal, natural gas, petroleum etc.
  • Conventional sources have cause immense environmental damage and has significantly contributed to global warming.


Conventional and Non Conventional Sources of Energy Part 1_3.1


Different types of conventional sources of energy


  • Coal is one of the most important sources of conventional energy.
  • Coal is the most abundant fossil fuel found in India and it has been the main source of India’s energy supply for many years.
  • Since the advent of industrialization coal has been most common source of energy.
  • There are around 150000 million tonnes of coal deposits in India. Out of which, deposits are mainly in the states of Odisha, Bihar, Jharkhand, Madhya Pradesh, and West Bengal.
  • India is the fourth-largest coal producing nation in the world.


Natural gas

  • It is an important source of energy in India.
  • Natural gas consists about 95% Methane and rest ethane and propane.
  • It occurs deep under the crust of the earth either alone or a long with oil above the petroleum deposits.
  • It is available in Tripura, Jaisalmer, off-shore areas of Bombay High and in the Krishna – Godavari delta.
  • It is used both as a domestic and industrial fuel.


Petroleum products

  • It is an important source of energy in India.
  • It is used in automobiles, trains, aircraft, and ships and other transportation vehicle.
  • The key oil-producing states in India are Mumbai, Assam, and Gujarat.
  • Some of the crude oil producing locations in our country are:
    • Ankleshwar and Kalol in Gujarat
    • Rudrasagar and Lakwa in Assam; and
    • Bombay high (off-shore area).


Conventional and Non Conventional Sources of Energy Part 1_4.1


Non-conventional sources of energy

  • The sources of energy which are being produced continuously in nature and are in exhaustible are called renewable sources of energy (or) non-conventional energy.
  • These sources of energy do not cause environmental pollution and are, therefore, environmental-friendly sources of energy.
  • Examples of non-conventional sources of energy: tidal energy, wind energy, hydel energy, solar energy, and geothermal energy.


We will discuss the different types of non conventional sources of energy in the next article.
