Wave Energy:

Wave is caused by the strong wind blowing on the surface of the ocean. A structure 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 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
