Who s contribution is this??? - please let me know - Horst

Wave energy is produced when electricity generators are placed on the surface of the ocean. The energy provided is most often used in desalination plants, power plants and    water pumps. Energy output is determined by wave height, wave speed, wavelength, and water density. To date there are only a handful of experimental wave generator plants in operation around the world. The articles on this page explore the world of wave energy and its possible applications.

- What is the effect on the environment?

Corrosion: Protection of metal constructions can be provided up to 30 years and more.

Pollutants: Wave energy companies use big volumes of hydraulic fluids, which may cause a leak of hydro fluid to the ocean.

Other benefits: Does not have any noise pollution, does not generate solid waste or wastewater, does not have any gaseous or CO2 emissions and is totally clean and pollution free.

Coast damage:

Oscillating water column is a type of energy generator with waves; are devices that generate energy from the rise and fall of water caused by waves in the ocean. As water rises and falls around and inside an OWC, air is displaced by the water in a collecting chamber and pushed back and forth past a Power-Take-Off (PTO) system. The PTO system converts the airflow into energy.

Does it produce carbon dioxide?

how does it works: you have 2 floating blocks, they are atteched to poles wich are atched to a rad, on that rad they atteched a dynimo, that dynimo generates the energy. (the dynimo works the same as yhat one you use on a bike)

Comment of Ms. Doolaard

Please add a picture of how it works and discuss what you can see on this picture.

-What is the effect on the enviroment? Waves-Brazil-Promotes-First-Power-Generator.jpg The generators used for wave energy do effect the enviroment a bit. the metal inside the water gets rusted fast cause of the salt cause of this the water gets dirty. Also waves destroy the coastline but that happens anyway cause we can´t stop them.So wave power has minimum effect on the enviroment.

Comment of Ms. Doolaard

What about the poor fish and pollution of the horizon?


Science exchange ‘wave power’ - How does it work? Most of the energy comes from the rising and falling water level and requires exposure to the waves. Currently, there are three basic technological paradigms for wave energy and various companies are pursuing their own designs in these areas.

- Where can you find “plants” of this source and why? The best wave energy environments are along western coastlines because the largest, most consistent winds come from the west. In the United States, wave power hotspots are California, Oregon, Washington and Alaska. Globally, wave energy leaders include the United Kingdom, Portugal, Australia and New Zealand. Northern Canada and southern Africa are other wave power hotspots, according to the U.S. Department of Energy.

-Can it be used in the Netherlands, why?/why not? no because, There are limited wave power opportunities in the East, when the shape of the land can sometimes yield energy resources.

Can you use this energy source in Spain?

Please say this in your own words.
