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.
