Wave power is the capture of energy of wind waves to do useful work – for example, electricity generation, water desalination, or pumping water. A machine that exploits wave power is a wave energy converter (WEC).Waves are generated primarily by wind passing over the sea's surface and also by tidal forces.

Wave energy converters (WECs) are generally categorized by the method, by location and by thesystem. Locations are shoreline, nearshore and offshore. Types of power take-off include: , , pump-to-shore.
Wave energy's worldwide theoretical potential has been estimated to be greater than 2 TW.Locations with the most potential for wave power include the western seaboard of Europe, the northern coast of the UK, and the Pacific coastlines of North and South.

The answer: Wave energy technology needs to be cheaper, produce more energy, and brave the ocean''s brawn better and for longer. Now, the marine energy team at the National Renewable Energy Laboratory (NREL), has designed a system that could achieve all three needs.
Now, the marine energy team at the National Renewable Energy Laboratory (NREL), has designed a system that could achieve all three needs. The variable-geometry, oscillating, surge wave energy converter creates windows for waves to pass through so wave energy devices don''t bear the full force of their power. The design could also be more cost
The theoretical estimate of global wave power is about 32,000 TWh/year (with a mean power of 3.65 TW) . In terms of the usable wave power resource, excluding areas with wave power level < 5 kW/m, the global estimate is around 3 TW, while the mean wave power experienced by global oceanic coastlines is about 2.11 TW .
Wave power is based on interaction between ocean waves and energy converters, specifically engineered to harness wave energy. The kinetic energy produced by the waves drives turbines, which then generate power that can be converted into electricity.
Wave energy conversion devices include rafts and pendulums, which are the most prevalent. The Wave Power Deliver firm (Yemm et al., 2012) has devised a raft-type wave energy conversion device (shown in Figure 4) that should be built at sea in water depths greater than 40 m.
Waves have a lot of energy. Waves form as wind blows over the surface of open water in oceans and lakes. Ocean waves contain tremendous energy. The theoretical annual energy potential of waves off the coasts of the United States was estimated to be as much as 2.64 trillion kilowatthours, which is equal to about 63% of total U.S. utility-scale electricity generation, in 2023.
