In this work, a systematic review was carried out, using keywords, through the scientific research databases of Science Direct and Web of Science, approaching the statistical methods used to assess trends in historical climate data. Among the articles obtained in this selection, a study was found in Brazil, which analyzed trends in climate parameters, evaluating the impact on the energy sector, in a small hydroelectric power plant and in a solar plant. Linear regression and the nonparametric Mann-Kendall test, associated with the Sen’s slope, were the most used statistical methods in the analysis of historical climate trends. Compared to others, these tests are less influenced by the presence of outliers. The most studied climatic parameters were precipitation and air temperature. It was noticed that few articles addressed climate trends in combination with impacts on the energy sector, especially those based on renewable resources, which are the most susceptible to climate change, opening a gap for further studies along this line.
