Abstract
Results of useful exergy accounting at the societal (i.e. national or global) level are potentially important for policy purposes, such as the development of energy or GHG emission scenarios, and the determination of the major energy inefficiencies (and thus improvement potentials) within a country. However, useful exergy societal studies commonly differ in their accounting methodology, which affect the results. Such differences include the starting point (primary or final energy), the method used to compute primary exergy, the classes of useful exergy categories considered, the definition of second law efficiencies, the inclusion (or not) of exergy inputs related with non-energy uses, and the inclusion or not of muscle (and human) work....

To help bring a more consistent approach to useful exergy accounting at the societal level, we review the methodologies of past studies, highlighting the differences and discussing their advantages and disadvantages in each case. Based on this, we select our preferred options, leading to a proposed common methodology that can be used to build national and international series of useful exergy. (Less)
