Incorporação da energia solar nas residências de Fortaleza: análise dos impactos para o sistema de produção e distribuição do nordeste

Abstract

Brazil has one of the cleanest electricity grids in the world, but it is highly dependent on hydroelectric generation and, consequently, on the randomness of the national rainfall regime, which makes our energy system highly insecure. Energy crises such as the ones in 2000, 2013 and the one we are experiencing today (2021) were the result of climatic instabilities that ended up depleting the reservoirs of our plants. Studies suggest that climate changes that generate water crises will be more and more constant, and in this context of concern with improving our energy security, the discussion about the feasibility of investing in alternative renewable energy gains momentum. Among them, solar energy, which will be the focus of this work. An environmental, social and economic feasibility was made for the implementation of photovoltaic systems in homes in Fortaleza, as well as the possibility of scaling it and what this would bring us in terms of energy and water security and economic return to those involved. The results of all feasibility were extremely positive about this investment and are organized in this document.
