Abstract

The Brazilian electricity matrix, with a higher percentage of renewable sources than the world matrix, stands out in hydroelectric generation, an advantage or vulnerability depending on the rainfall regime, the volumes of the reservoirs, and the need to activate the thermoelectric plants. This work analyzes technical, economic, and the management aspects related to decisions about the composition and use of the Brazilian electricity matrix. The method was fundamentally based on the literature review. We seek answers about energy availability to meet Brazilian demand and whether government decisions can be considered the most appropriate. We analyzed the Internal Electricity Supply in Brazil since 1970, crossing it with data on population growth and GDP growth, comparing it with the evolution of the installed capacity of energy generation.
