Understanding the interactions between energy and the economy in society is crucial if we are to navigate the future challenges of climate change and providing wellbeing for all. The thermodynamic concept of exergy, which reflects the quality of energy in units of work, helps us to trace the transformation of energy along supply chains and quantify the efficiency and losses from energy conversion. Useful exergy (UE), the useful part of energy that is delivered to the end of each energy chain, is an informative metric due to its close association with economic metrics, such as GDP.
A burgeoning community of academics are now interested in developing the use of exergy to understand industrial and economic systems. The community has been catalysed by five International Exergy Economics Workshops: 2014 at the University of Leeds, 2016 at the University of Sussex, 2018 at the Instituto Superior Técnico/University of Lisbon, 2020 (virtual), and 2021 (virtual).
On 27 June – 29 June 2022 the sixth International Exergy Economics Workshop (IEEW2022) was held in Fitzwilliam College, Cambridge. 30-40 researchers met over 3 days to discuss past, present and future research.
