Over the years, the energy has been assuming a role that is becoming gradually more and more important in the society. The development of several fields, that impact directly in the life quality of the population, is supported by the energy and the world would probably collapse if there was a sudden absence of it. However, the energy in the quantities currently used are not easy to generate, transform and distribute. If these processes are not performed correctly, several actives would be compromised, compromising as well the quality of life. Thus, it is presented the importance of having an institution which its only goal is to promote the efficiency of all the processes related to energy, the National Agency of Electrical Energy, in the Brazilian’s case.
