Due to the affordability of renewable solar energy, it has now been seen as a competitive source of energy in comparison to other energy sources such as oil or coal.

Several technologies help in accomplishing this task. Solar power plants are used for the conversion of sunlight into electricity. Photovoltaic cells use concentrated solar power for the same purpose.

Uses of solar energy:

  • Many households use this natural form of energy in heating, drying, and cooking purpose.
  • Solar cookers are nowadays used to cook food with the help of Sun’s energy.
  • To produce electricity via heat engines or solar cells
  • To remove salt from seawater.
  • To use the heat of the sun’s rays to dry towels and clothes.
