Ever since the idea of global warming came up, scientists and researches around the world have been trying to find alternative energy sources to help reduce CO2 emissions. In the past, we have had a small amount of energy from solar panels and wind. Those are now being used more and more. Given the fact that the earth is 3/4 water, we are finally looking into using water power to generate electricity. According to the ABC Science article Wave Power, the technology for this wave electricity is still being developed and there are high hopes for it succeeding. It is mainly being tested and worked on in the UK and Europe, but is slowly becoming a global focus and idea. Andy Baldock, a UK wave energy analyst, says, "Waves are caused by wind blowing over long stretches of water, and [that wind] gets stronger towards the poles... That means that Australia and New Zealand have got good resources, as well as northern Europe, Canada and northern USA." The technology is starting to get more finalized and secure and now we also have an idea as to where the technology would be placed. Some are looking to use pilot wave power units (rest on the waters surface), which has chambers to help displace the air by moving up and down. The air is then forced inside a turbine to create the energy which then travels through a pipeline back to the land it is nearest. There are also other technologies being testes such as floats which move with the waves creating electricity and pure drinking water by bringing water to land at a high pressure. I am a huge supporter of alternative energy sources and trying to create a "green" planet. I feel if we have the technology, we should execute the idea of wave power. It is all around us and is such a huge part of earth. We need to use what we have and water is definitely easily available. GO WAVE POWER! I couldn't get this video to upload, but for an example of wave energy go to this link:
