Energia como função de Estado no contexto da eficiência energética .

Abstract

From prehistory to the present day, the use of energy is closely related to the development of societies. Nowadays, there is no definitive definition what does energy means. However, the physical laws that involve most of the energy conversion processes are known. In particular, those related to the conservation and dissipation of energy, and it is essential to the sustainable and efficient use of available resources in nature. In this work, energy is presented as state function in the context of energy efficiency, based on a systemic approach, and a multidisciplinary perspective, through studies on the concepts and fundamentals of the subject under study. Finally, state equation and their state variables are presented in electrical and thermodynamic systems.
