Solar Energy 

               In India most of the electricity is generated through thermal power plant (coal).  But, as days passing, coal in the earth is getting reduced. And these power plants not only generate electricity but also results in air pollution, global warming and depletion in ozone layer.

                In order to overcome these issues we go for renewable energies such as

  • Solar energy
  • Wind energy
  • Hydro energy
  • Tidal energy
  • Geothermal energy
  • Biomass energy

              As for now, we look at solar energy. Solar energy takes heat from the sun and converts it into electricity. It doesn’t harm the environment as non-renewable energies do. And now-a-days solar power plants are being used widely all over the world.

 Advantages of solar power plant:

  1. Its maintenance cost is less.
  2. It can be used anywhere all over the world.
  3. It doesn’t produce harmful radiation.
  4. Electricity bill can be reduced.
  5. It doesn’t waste any resources.

             Although there are so many advantages of solar power plant but there are some disadvantages of this plant. They are:

  1. Initial cost of this plant is high.
  2. It depends on the weather conditions like if it is a cloudy day, then, the efficiency of the plant drops.
  3. It takes a lot of space.

                  Generally, solar thermal energy is of 3 types. They are:

  1. Low temperature – which is used for heating and cooling the air.
  2. Moderate temperature – which is used for heating the water.
  3. High temperature – which is used for generating the electricity.
