Wave energy is renewable and emissions-free form of energy production. It can have a local environmental impact on the site where the plant is placed. The nature of the impact is difficult to ascertain since this technology is so new, but there are indications that the wave power can have a positive impact on the local biotopes. This positive impact is the result of wave power plants acting as artificial reefs with increased growth for both micro and macro fauna as a result. Ocean waves have a lot of energy and the potential for almost continuous utilisation. It is estimated that wave power could cover 10% of the entire world’s electricity needs.
