The dynamics of renewable energies in the Brazilian energy matrix in the 21ST century

In the early 21st century, Brazil began adopting a series of energy policies aimed at analyzing and understanding the dynamics of its energy matrix. In this context, this article aims to analyze the dynamics of the Brazilian energy matrix based on the main energy policies adopted in the early 21st century. The research methodology begins with a bib-liographic review on the topic, directed at understanding the studied dynamics, as well as the construction of a theoretical framework from directly and indirectly related works. The bibliographic survey was conducted through research in libraries, digital repositories, and scientific journals, referencing books, dissertations, theses, databases, and articles related to the topic. This investigation is important as it deals with energy-related issues that are related to climate concerns. We conclude that, based on existing data, although there are concerns and debates about the environment and climate change in Brazil, there has been little progress in terms of the percentage of renewable energy sources incorporated into the Brazilian energy matrix between 1990 and 2020. Examining the Brazilian energy panorama in 1990 and 2020, we can see that the share of renewable sources reached 49%, making it the highest percentage of renewable sources in the internal energy supply during this period of analysis, with 51% of non-renewable sources.
