Since wave energy is still relatively new, there are fewer areas that currently have or are installing wave farms. It's about 3 miles offshore, north of Porto, and was designed to use 3 Pelamis wave energy converters. It has an installed capacity of 2. Due to the financial collapse from an economic crisis, however, it was shut down. United Kingdom. In May, , a wave farm currently 66 machines was launched in Scotland.
Off the north coast of Cornwall, England, the Wave hub facility acts as a giant extension cable. It allows 20 MW to be connected to it, but could go up to 40 MW. It also could end up powering up to 7, households and save around , tons of CO2 in the next 25 years. Australia have wave farms that are currently under development off the West coast and near Portland, Victoria.
There is also a greenWave device off of Southern Australia. The Reedsport farm was supposed to be installed in , but due to legal and technical problems, the project came to a halt. Wave energy has a lot of potential. Wave energy also has many different positive aspects.
First, the energy is green. Harnessing wave energy doesn't emit any harmful gases, and it can easily replace energies that do, such as using fossil fuels. Ocean waves have a lot of energy, and wave power is a renewable energy source capable of generating electricity. Harnessing the Power of the Waves There are three main methods for harnessing energy from waves and converting it to electricity. Share this article. Share on Facebook. Share on Twitter.

Top Stories Environment How to keep beaches clean days a year. The beach is the final frontier between land and the ocean. Portugal is heavily subsidizing the Pelamis project, with an eye to becoming a major European exporter of clean green power in the future. Little is known about the effects that large wave or tide farms might have on marine ecosystems in general.
Despite the uncertainties, however, proponents say the potential advantages are too striking to ignore. Eight hundred times denser than air, moving water packs a huge energy wallop. Like solar and wind, power from moving seas is free and clean. But sea power is more predictable than either wind or solar. Waves begin forming thousands of miles from coastlines and days in advance; tides rise and fall as dependably as the cycles of the moon.
That predictability makes it easier to match supply with demand. Roger Bedard, who leads ocean energy research at the U. Within a decade, he says, the U. Although he acknowledges that initial sea-powered generation projects are going to be expensive, Bedard believes that as experience grows and economies of manufacturing scale kick in, hydrodynamic power will follow the same path toward falling costs and improving technologies as other alternatives. Any future tax on carbon emissions could narrow that gap even more, as would additional clean-power subsidies.
For some nations, wave and tide power could pack an even bigger punch. Estimates suggest, for instance, that the choppy seas surrounding the United Kingdom could deliver as much as 25 percent of its electricity. Diesel fuel. Heating oil.
