How are conventional sources of energy different from non-conventional sources of energy?

How are conventional sources of energy different from non-conventional sources of energy? Explain any five points of distinction.

Conventional sources of energy are coal, petroleum, natural gas, firewood cattle dung cake and thermal and hydel electricity while solar wind, tidal, geothermal, biogas and atomic energy are the examples of non-conventional sources of energy.

  • Conventional source of energy have been in use since long, while non-conventional sources of energy have been in use only recently.
  • Conventional sources of energy except water power are exhaustible, while non- conventional sources of energy except nuclear energy are inexhaustible.
  • There is uneven distribution of conventional sources of energy while wide distribution of conventional sources of energy except nuclear power.
  • Except water, power conventional sources are pollution free while non-conventional sources of power are pollution free except nuclear power.
  • Huge capital is required for establishing plants of conventional sources of energy while less capital is required for establishing plants for non-conventional sources of energy.
