摘要：The challenge of sustainability is present in electricity generation. The sources should be renewable, andproduction should respect the environment and all forms of life. Being the main energy sources in Brazil,hydroelectric and thermal power plants have drawbacks when considering environmental impacts. Incontrast, the use of photovoltaic energy is a sustainable alternative, pollution-free in its operating phaseand with significantly less impact in its construction phase. The purpose of this article is to make arelation between the electricity generated by the hydroelectric Itaipu plant, the thermoelectric complexJorge Lacerda, the Eletronuclear plant, and the analysis of a photovoltaic plant proposal for these threescenarios. The relation between the production of electricity in Itaipu, Jorge Lacerda, and Eletronuclearpower plants, and the projected energy production of a photovoltaic plant for each scenario was obtainedthrough calculations according to the area of each plant, generating a comparison between the installedpower of the referred plants, and the estimated installed capacity for the projected photovoltaic plant. Theenvironmental impacts were assessed for the different scenarios, and CO2 emissions were quantified. Thecalculated results show that the installed power of the projected photovoltaic plant was significantlyhigher than the installed power of the existing plants. The photovoltaic plant’s capacity factor, for theproposed study, was of 15%, and the projected annual photovoltaic energy for the respective areaspresented significantly higher values, of approximately 330,180.40 TWh in comparison to Itaipu plant,while in comparison to Jorge Lacerda plant, for instance, it was of approximately 428,229.23 TWh,whereas to Eletronuclear it was 0.0288 TWh. The results of this study show that photovoltaic plants withequivalent areas of Itaipu and Jorge Lacerda power plants, could generate higher annual energy,nevertheless the same analyses to Eletronuclear power plant showed that the projection would not beviable.
