Class 10 Physics Sources of Energy Wave Energy

Wave Energy

  • Wave is caused by the strong wind blowing on the surface of the ocean.
  • Kinetic energy of waves is used to generate electricity.

 

  • A structure(as shown in the figure) is erected in the sea which has a piston attached to a turbine.
  • The other end of the piston touches the ocean water.
  • When there is a rising wave, the level of water increases, pushing the piston upwards. The piston is in turn connected to a turbine which rotates and electricity is produced.
  • When there is a falling wave, the level of water decreases, pushing the piston downwards. The piston is in turn connected to a turbine which rotates and electricity is produced.

Advantages of Wave Energy

Disadvantages of Wave Energy

·         More reliable (more than solar/wind)

·         Renewable

·         Low maintenance cost

 

·         Initial cost is very high

·         Not environment friendly because setting up of a plant could harm aquatic plants and animals.
