What is wave energy?

Wave energy is the capacity of the waves of doing work. It is a renewable energy. Ocean waves are generated by the influence of the wind on the ocean surface.Waves are generated by wind passing over the surface of the sea. As long as the waves propagate slower than the wind speed just above the waves, there is an energy transfer from the wind to the waves. Both air pressure differences between the upwind and the lee side of a wave crest , as well as friction on the water surface by the wind, making the water to go into the shear stress causes the growth of the waves.

How wave generator works?

A wave generator at a costal site uses the motion of waves to make a floating section move up and down. This motion drives a turbine which turns a generator. A cable between the generator and the shore delivers electricity to local users or via a network of cables to distant users.Wave generators need to withstand storms and they don’t produce a constant supply of electricity. , Furthermore, lots of cables would be needed along the coast to connect the wave’s generators to the electricity grid. This would spoil the views of the coastline. In addition, tidal flow patterns might be changed, affecting the habitats of marine life and birds.

How ocean waves are caused?

Ocean waves are caused by the wind as it blows across the sea. Waves are powerful sources of energy. This problem is that it’s not easy to harness this energy and convert it into electricity in large amounts. This wave power station is rare.

Environmental ConsiderationsPotential environmental considerations for the development of wave energy include the following: • Positive or negative impacts on marine habitat (depending on the nature of additional submerged surfaces, above-water platforms, and changes in the seafloor); • Toxic releases from leaks or accidental spills of liquids used in those systems with working hydraulic fluids; • Visual and noise impacts (device-specific, with considerable variability in visible freeboard height and noise generation above and below the water surface); • Conflict with other sea space users, such as commercial shipping and recreational boating;
