Wave Energy is one of the niche Water Energy Technologies that is still in its infancy stage in terms of technology maturity.Wave Energy has been around a long time with around 350 patents being granted for this technology and around 200 startups working on this renewable energy form.Wave Energy basically derives power from the movement of waves to generate electricity or power.Wave Power exists due to the differences in the speed of ocean water and wind power.The energy is transferred by the Wind Energy to the Waves which can be utilized to generate power.A wide variety of wave energy generators like buoys,underwater devices are being developed to harness the power of the waves in a cost efficient manner.Wave Energy Research is concentrated mainly in the United Kingdom which has made tidal and wave power central to meeting its 2020 European goal for renewable energy.Edinburgh in UK has become a center of wave energy development and EMEC has developed Cornwall as an important site for demonstration of wave energy projects.Some of the wave power companies are listed on the stock market as well.Due to the technology immaturity ,most of these stocks are micro cap and not an investible class for big investors.

Wave Energy is being developed for a long time almost since the 1700s through a variety of devices and convertors.Wave Devices are being used mainly to generate electricity and for water desalination.Wave Energy has a myriad of systems being developed as the technology is still immature.Wave energy generation is still a research field and there are as many designs as companies active in this field.Note as a technology matures,a single technology system gain ascendance as others are discarded along Darwinian lines.For example solar technology which is in the phase before maturity has majority of its energy convertors of the mainstream polycrstalline solar panels.Wind Energy which is further along the learning curve has most of its energy being generated from large vertical axis wind turbines.Wave Energy on the other hand has not come around a single dominant type of device.A number of devices are being developed to harness wave energy efficienty and at low cost.Wave Energy faces problems of being exposed to strong weather elements therefore wave energy designs are progressing along the lines of devices which require low maintainance and which are able to withstand weather better through devices with lower number of moving parts.
