Ocean wave energy as a possible power source for the brazilian energy matrix

Energy is a fundamental element for the development of societies, with energy transformation from renewable sources a challenging theme throughout the world. In Brazil, the energy matrix is composed mainly of non-renewable sources such as petroleum and its derivatives, but the transformation for electricity supply is carried out mainly by hydroelectric plants. This paper presents data from the National Energy Balance between the years 2011 to 2016, regarding the internal supply of energy, as well as the sectors that use it as their main source of electricity, allowing a better visualization of the national scenario. In view of the problem, the main objective is to present possibilities for the production of energy by ocean waves, a concept already studied in developed countries. For example, three tested converter devices are considered: One in Norway and two in Denmark. Considering this possibility from the power of the ocean waves in the world, as well as the climatic, geographical and wave characteristics of Brazil, this work indicates the possibility of a significant increase in the Brazilian energy matrix through the use of the energy of the ocean waves. However, there is a growing need to foster research and development projects in this area, so that this alternative source of energy will become viable. © 2019 Trans Tech Publications Ltd, Switzerland.
