ABSTRACT
In general, historically, Brazil is a country that does not develop a robust master plan for various areas responsible for supporting its development. As for the themes: education, transport, logistics, tourism, among others, the national infrastructure, in which the generation of electricity is a main character, does not have a strong planning and is pursued firmly that its actions come true. In addition, there is no clear driver for the system to seek in order to become more sustainable, reducing the economic, environmental and social impacts from the conversion of the energy potential of natural resources (renewable or not) into energy for society. The capacity of electric power generation is strategic for any country; it drives its economy and consequently its economic growth and increases the quality of life of its population. However, a robust planning is required to optimize the economics of electricity generation facilities in order to always meet the demand, without any significant spare capacity. Additionally, it is necessary to balance and evaluate the options available, so as to have a generating capacity which fulfills in addition to economic benefits, greater energy efficiency and reduced environmental impact, in order to allow the model to be sustainable. Thus, this paper presents the history and projections of population growth, evolution of GDP (Gross Domestic Product) correlated with the consumption and generation of electricity, as well as performs a calculation of the exergetic efficiency of Brazil’s generating capacity for the production of direct correlations with its economic ability and associated environmental impacts, including the likely projections, providing means for reflection on the possibilities of planning and drivers for the future as well.
