Aspectos gerais dos impactos ambientais provocados por empreendimentos de geração de energia hidrelétrica : uma abordagem bibliográfica

Abstract

After the industrial revolution there was a great increase in population in Brazil and consequently increased consumption of natural resources which caused an increasing search for mechanisms of energy production using the gravitational force of flowing water. The dams are considered the main option electric power production, since the technique is economically viable mainly by using natural resources that the country has in abundance. However one must know the effects caused by this type of project on the environment. This study aims to identify the environmental impacts of hydroelectrics, verify the procedures for implementation of these projects, check if there are and what are the procedures for environmental monitoring. The research followed the precepts of the exploratory study through a literature search which according to some authors consulted is developed from theoretical and historical consisted of a literature that includes books, papers and other essentials. It was noted that many plants have impacts, both positive and negative, that there is environmental monitoring and that under a broad point of view, one can assume that in general the advantages of plants prevail since the energy is widely need for almost all human activities. However the environment in which they are installed shall be thoroughly analyzed and carefully because of the impacts.
