How does wave energy work?


Quick Answer

As the wind hits the surface of the water, the energy transfer of the wind to the water causes the water level to rise and fall, producing waves. To generate wave energy, a technological device that sits in the water is then used to make electricity from the waves, and a cable is used to transfer this electricity to the power grid for use. One of the main benefits of this type of energy is that it is highly renewable.

Some of the technological devices used in wave energy include an oscillating body, over topping device and oscillating water column. The oscillating body uses an electric generator that is driven by the up-and-down motion of the waves, while an oscillating water column uses a turbine with decompressed air. An over topping device uses the draining of the water in a basin to produce electricity.
