Abstract
Energy systems need to be more efficient in order to guarantee a sustainable development in face with the challenges of Climate Change. Exergy analysis is a powerful concept to measure the quality of energy and the irreversibility associated with its use. São Paulo, the most populous and rich state in Brazil, was considered as the region of interest in this present study. The Residential, Commercial, Public and Transportation sectors were evaluated using exergy analysis and their respective energy and exergy efficiencies were calculated. As expected, the exergy efficiency was significantly lower than the energy efficiency. The exergy efficiency was then compared with the existing works available in the literature and it was found that São Paulo’s exergy efficiency is well within the range of other regions and countries. The effect of some efficiency improvements and the use of cleaner energy sources were tested within the model for the sectors considered. Exergy efficiency was then calculated to measure the impact of such improvements. The results are useful as a guidance for public policy envisaging a better use of our natural resources in less harmful ways to the environment.
