Make a list of conventional and non-conventional sources of energy. Give a brief description harnessing one non-conventional source of energy.

Explanation

Conventional Sources of Energy
(i) Fossil fuels
(ii) Hydro-electric power plant
(iii) Thermal power plant
(iv) Biomass
Non-conventional Sources of Energy
(i) Solar energy
(ii) Tidal energy
(iii) Nuclear energy
(iv) Ocean thermal energy
Harnessing Tidal Energy:
(i) For this, a cylindrical structure is vertically placed in coastal areas where tides come.
(ii) A turbine is fitted at the top of this cylinder.
(iii) When the tide comes, air gushes through the cylinder. This turns the turbine and electricity is generated
(iv) When the tide goes, air moves in opposite direction. This also turns the turbine and electricity is generated.
