Wave power harnesses the energy of ocean waves to generate electricity. It is a renewable and relatively cheap energy source that can power various operations. The technology uses chambers that capture air pushed by waves to spin turbines. Critics are concerned about the visual impact and noise, but proponents hope the benefits will outweigh the concerns. Many energy companies and governments have invested in wave energy research.
Wave power is a form of alternative energy that harnesses the natural motions of the world’s oceans. In the late 1990s, a number of companies began exploring the possibility of wave energy, and in the early 2000s, a number of experimental installations were made around the world to see how feasible wave energy could be. It is believed that, if harnessed correctly, wave energy could generate massive amounts of electricity that could be used to run operations such as desalination plants, electric water treatment plants, and homes and electric utilities for consumers. As a result of the initial success, several nations invested more in the idea.
The concept harnesses the energy already abundant in the ocean, which manifests itself in the rise and fall of water in the form of waves. One of the easiest ways to capture this energy is through a simple inner tube. As the waves rise and fall in the chamber, they push air through the top, spinning a turbine that can be used in electricity generation. These chambers can be mounted on the shoreline, or they can be positioned out at sea in the form of large floating buoys.
There are a number of significant benefits to wave energy that make it highly attractive to alternative energy enthusiasts. The first is that wave energy is a truly renewable energy source, as it takes advantage of the natural processes already taking place. Furthermore, wave energy is relatively cheap once the structures are in place and especially if it is used locally, the cost to move the energy is also quite minimal. Also, wave energy plants would not take up valuable land, as is the case with solar panels and wind farms.
There are also some concerns about wave power, although most of these concerns are cosmetic. Critics say people will find the look of wave power plants unappealing and that this form of power generation could spoil many excellent views. Wave power will only be successful in a few high-energy ocean areas, and many of these areas are also beautiful and popular vacation spots. Critics are also concerned about the noise, which could be significant. Besides disturbing human life, the noise could also distract the animals that call the ocean home.
Many of the concerns about wave energy are valid, but proponents of the technology hope the benefits will eventually outweigh these concerns. Many large energy companies seem to agree, as a number of companies have invested in significant wave energy research. Governments have also promoted the technology as an environmentally friendly alternative to other methods of generating electricity.
