Wave energy is obtained from ocean surface waves and is a renewable source of energy. Waves are generated by wind blowing over the surface of the sea or ocean. Several technologies have been designed to capture this wave energy, including wave energy converters that extract electricity from wave motion. These devices are installed offshore and can operate in water depths up to 40 meters. Common wave energy converters include devices resembling fins that extend vertically to catch wave energy, and machines located under water that use wave motion to push air through a turbine to generate electricity. The world's first commercial wave power plant using these technologies has been installed off the coast of Scotland.

2. Wave Energy

3.  Wave energy is obtained directly from the surface of
wave or surface wave under the pressures. The
waves are generated by winds blowing from the
surface of the sea or ocean.
What is Wave Energy ?

4.  Permanent waves create winding up in many parts of world
regularly and continuously.
There is a lot of energy in the waves of the sea and the ocean.
By movement of surface waves, wave machines produce wave
energy directly from the wave pressures.
What is Wave Energy ?

5.  To use wave energy effectively many types of technology are
designed. Some of the most suitable ones are being tested for
commercial use.
 Where can you find wave energy?
Generally, extreme latitudes and west coasts of continents.
View global wave atlas (based on satellite data) and another
world wave map The world’s first commercial wave energy
plant, .5 MW, developed by Wave Gen is located in Isle of Islay,
Scotland.

6.  Wave energy technologies are installed in the open
sea a bit away from the shore. The active depth of
surface wave is until 40 meters. What are wave
energy devices called?
 Waves have the potential to provide a completely
sustainable source of energy, which can be captured
and converted into electricity by wave energy
converter (WEC) machines. These WECs have been
developed to extract energy from shoreline out to
the deeper waters offshore.
Wave Energy

7.  Although all wave energy
technologies are designed to be
installed on the water surface or
near the surface of the water, they
differ according to appropriate
waves for them and the energy
they convert to.
Wave Energy

8. The finisher machines extend
vertically in the direction of wave
motion and they reflect or catch
the energy.
The working principle of Wave Energy

9.  Recent versions of this type of machine is designed
to be installed in places close to the sea and are
usually designed to be installed on the beach or near
the beach.
The working principle of Wave
Energy

10.  Vibrating machine is another variation of the water
column terminator. This machine is located under
the surface of the water and the water goes into a
part which includes compressed air in it.
The working principle of Wave
Energy

11.  Wave motion which allows the water to move up
and down like a piston pushes the air through the
turbine connected. And the turbines generate
electricity.
