Diversification of energy sources, notably those classified as renewable, is a worldwide trend, with the UN Sustainable Development Goal No. 7, called Agenda 2030 (UN, 2015). In the last few years, Brazil has used more than 40% of its consumption from renewable sources of electricity, which is much higher than the world average and OECD countries (EPE, 2018). Currently, wind and photovoltaic energy have stood out with strong growth in participation in the Brazilian energy matrix. Considering that the subsidy for renewable energy is shared among all consumers, understanding the impact of subsidies on the development of the use of these energy sources is necessary for the evaluation of the results obtained. Studying the wind and photovoltaic sources, which have been highlighting in the world scenario, is important for the understanding of this phenomenon. The objective of this work was to analyze the evolution of the participation of wind and photovoltaic energy sources (EFV) in the Brazilian energy matrix of electricity generation in the period from 2013 to 2017. The data used were extracted from the National Electric Energy Agency using the Microsoft® Excel® 365 and R ver. 3.5.1. For this, both descriptive and numerical summary methods, as well as methods of normalization and Pearson's correlation, were used. It was found that the increase in the participation of these energy sources in the Brazilian energy matrix is consistent, even with the climatic limitations occurring in certain parts of the year, indicating that government subsidies have taken effect.Downloads
