Abstract
The energy matrix defines the set of resources required by a country to supply the energy needed to carry out its productive processes (Gomez, 2015). It involves all energy harnessed from every energy source applied towards the country’s endeavors across every single industrial and technological sector (EPE, 2016). Two are types of resources available: (i) primary (e.g.: oil, natural gas and coal), understood as energy sources from nature (not undergoing transformation processes) and (ii) secondary (e.g.: gasoline, diesel, electricity), obtained from raw materials that undergoes transformations (Marcoccia, 2007). The Brazilian energy matrix —National Energy Balance (Balanço Energético Nacional, BEN)—, annually prepared by the Empresa de Pesquisa Energética (EPE) and published by the Ministério de Minas e Energia, MME (Ministry of Mines and Energy), constitutes a fairly complete document, regularly published since 1970, widely used by both, the government and the private sector, instrumenting their planning and investment activities (Vichi & Mansor, 2009). Figure 1 illustrates the actual Brazilian Energy Matrix. These data were recently published by the Energy Research Company (EPE, 2017) and synthesize energy supply as well as energy demand by the various sectors of the national economy. As shown, on the hand there exists a strong dependence on Petroleum and its derivatives (36.5%), on the other hand, less polluting energy sources, such as sugar cane (17.5%), slightly increased its energy production compared to that of 2015 (15.4%). This confirms that efforts to make the energy matrix increasingly sustainable have become important.
