Wave Energy: Pros and Cons

Wave power is one of the alternatives used nowadays in promoting better solutions for the energy problem with which the world in confronted. Along with solar energy, biomass, wind energy and several other types of sustainable energy, wave power is one of the most researched areas of renewable energy. This article is aimed at explaining how wave energy can be the solution for the major problem that the world has when it comes to energy.

Wave power results from the transport of energy by ocean surface waves and its capture into systems that can be therefore used for useful applications. Some of these applications include electricity generation, the pumping of water, or water desalination. It is estimated that specialists have been attempting to use wind energy since the late 1800s. However, this type of energy generation technology is not very common currently and it is certainly one of the least employed commercial technologies. Moreover, it is estimated that the first known patent to utilize energy from oceans waves was provided in the last year of the 1700s. An early application of the concept was used in 1910 to light and power the house of the inventor, Bochaux-Praceique, in Bordeaux, France. The specialists who filed it were from Paris and they are known under the name Girard and his son. The first experimental wave farm was opened in Portugal in 2008, at the Aguçadoura Wave Park.

Wave power seems an efficient way to produce more energy and to partially solve the energetic problem that we are witnessing. However, as any other type of renewable energy, it is costly and it is still under an experimental phase. Yet, it is limited to several geographical regions and only countries with an opening to a large sea or ocean may take advantage of its benefits.
