When we think about energy, we consider it in terms of quantity. However, in a resource-constrained world, energy and in particular its efficiency, must also be appreciated from the point of view of quality, which is its ability to do work. In order to include the quality and not just the quantity of energy, we need to measure ‘exergy’. This brochure introduces the concept of exergy and provides examples of its application… read more
Exergy is the resource of value, the energy available for work; a measure of both the quality and quantity of available energy. Exergy analysis not only tells the truth about energy efficiency, but, in an extended perspective, potentially leads to resource accounting on a global scale: a common scale for our common future. In this Opinion Paper, the Science Europe Physical, Chemical and Mathematical Sciences Committee builds on a recent peer-reviewed publication, ‘A Thermodynamic Metric for Assessing Sustainable Use of Natural Resources’, to reach out to policy makers… read more
This workshop was convened by the Science Europe Scientific Committee for Physical, Chemical, and Mathematical Sciences to explore issues surrounding the concept of ‘convergence’ and its potential relevance to, and implications for, research funding organisations and research performing organisations in Europe… read more
