Análises de eficiência energética em faturas elétricas com ênfase na redução de custos: estudos de caso consumidores do grupo A e grupo B

Abstract

The scarcity of fossil fuels, the gradual and accentuated increase in prices in some sectors such as electricity and automotive, and environmental problems have led to a concern among world leaders who are committed to implementing measures that ensure greater energy sustainability. This sustainability is primarily based on energy efficiency. Energy efficiency in general means doing more or at least the same thing, using or producing less. There are various applications of energy efficiency currently, such as studying air circulation in buildings, lighting studies, studying the reuse of electrical equipment, as well as the study of energy efficiency in electrical energy bills. Changes in tariff systems applied by resolutions of the National Energy Agency (ANEEL) affect the cost of electricity, and as a result, unsuspecting consumers are harmed due to their ignorance of their consumption characteristics and the tariff system they are being enrolled in. Due to the current electricity scenario in Brazil, the Brazilian nation has witnessed its largest recorded water crisis in recent years, advances in the prices of products and raw materials, and consumers are seeking alternatives to mitigate and reduce the costs caused by electricity consumption. One way to apply energy efficiency through electricity is to analyze consumers' electricity bills, presenting solutions to reduce the costs generated by the use of energy, either by electrical consumption or contracted demand, bringing cost reductions in electricity bills and efficiency to the concessionaires' systems and consumers. The purpose of this work is to analyze the effects caused by the recommended changes through energy efficiency techniques that have been developed and present the techniques in four case studies with real consumers and the elaboration of an energy efficiency technique manual with the aim of disseminating the concept of energy efficiency, so important in today's times.
