Wave motion transfers energy from one point to another, often with no permanent displacement of the particles of the medium—that is, with little or no associated mass transport. A disturbance on the surface of a liquid body, as the sea or a lake, in the form of a moving ridge or swell is also called wave. One type of wave is a mechanical
wave, which propagates through a medium in which the substance of this medium is deformed.
The deformation reverses itself owing to restoring forces resulting from its deformation. Another type of wave can travel through a vacuum, e.g. electromagnetic radiation (including visible light, ultraviolet radiation, infrared radiation, gamma rays, X-rays, and radio waves).
Wave power is particularly beneficial for coastal regions where waves are strong but is mainly used further into the sea with large scale wave farms which draws energy from the currents and tidal waves. Wave power is not dissimilar to wind power, the more wind we have the better the waves will be in addition to the natural current. Wave power generators are inherently ecologically-friendly. Without a need for fossil fuels, and
with no harmful chemicals released, wave power stations such as the “Duck” and the “Sea Snake”
do not pollute our atmosphere or deplete the earth’s supply of non-renewable fuels. They are also quiet in operation with many turbines emitting less noise than a vacuum cleaner, so there is practically no noise
