What is a wave energy technology?

Wave energy technology uses rising and falling roots of surface waves driven by tidal forces on the ocean to produce electricity, either from direct water flow or pressure effect that water can have on surface streams of air. While Wave Energy Technology technology offers a promise that it is basically free energy and completely renewable, its impact on the marine environment is largely unknown. This technology is also in the development phase where prototypes are tested, which could eventually be reduced to provide a large amount of energy for coastal cities. The turbine is designed to move the rotation in response to rising or falling when changing the air flow so that it rotates. However, the process generates a lot of noise, which is one of its main disadvantages.

another method uses a large, floating, elongated pelamis tube that bobs up and down tothe surface when the waves pass below them. This moves the lever attached from each tube to the hydraulic pump that controls the electrical generators. A similar hydraulic design uses equipment that sits on the seabed, connected to floating units that move as a piston when the waves rise and fall, to pump seawater through generators. The energy technology of the oyster wave technology also uses the pumping effect of waves to open and close the hydraulic panel, which pumps the liquid to the coastal station, where the pressure is again used to control the electric generator.

In the US since 2007, the projects of experimental waves on the Oregon coast have the date of completion between 5 and 10 years, and it is assumed that they will create enough for maximum capacity to supply 60,000 households. The devices are used by buoys depicting wool located in the Pacific Ocean and complement similar experiments by the states of Washington, Hawaii and New Jersey. Testing is performed while attempting to assess the impact of systems onthe environment.

While American programs are largely experimental, Europe is in the development of wave energy technology. During the European sector, Wave Energy technology has been studied for more than 25 years with different levels of support and public success. Problems with expanding the expansion of tidal energy systems to practical levels include irregularity in the size and direction of the wool, the structural ability to handle extreme ocean weather patterns and adapt the design of the device so that it is effective in using slow and irregular wave movements.

The ability to use energy from the waves is directly proportional to the squares of their amplitude or the period of time between the ridges and their size. As a result, the waves are generated in the latitudes of 30 ° and 60 ° north and southern widths around the world. European nations with the highest potential to connect to this energy source are Iceland, United Kingdom and Ireland, as well as northern Spain and SouthNorway.

estimates are that the total amount of ocean energy available along the European coast is in the size of 320 gigawatts. It is believed that the coast of Great Britain will have the ability to produce 67 gigawatts of electricity from wool technology. For comparison, the United Kingdom, since 2008, had the capacity of electricity production of 76 gigawatts of energy from traditional oil, gas and renewable sources.

Environmental concerns about the location of the wave energy generator focus on five wide areas. The effects of multiple wave energy devices on Littoral or Shoreline dynamics and bentic ecosystems at the bottom of the shallow areas of Water are studied. Research of electromagnetic areas that the wave technology creates and have on the surrounding fish habitats and migration samples is also investigated. Overall effects on local life cycles of marine mammals and marine birds are also studied.

Further concerns about wave energy farms along the coast include their effect on recreationActions, their noise pollution and potential risk for navigation of transport. Despite these disadvantages, since 2008, global prototypes have produced two megawatts of power. The estimated worldwide production was estimated at 2,000 gigawatts per year, or 10% of the entire electricity consumption in the world in 2008. In order to reach such a production level, investment costs were estimated at EUR 820,000,000 ($ 1,173,830,000,000).
