Dr Paul Brockway


I joined the University of Leeds in 2015 as Research Fellow, before promotion to Senior Research Fellow in 2017. I was awarded a 5 year EPSRC Early Career Fellowship in 2018, and am also now a University Academic Fellow.

My transition to the area of exergy economics started in 2002 with a 2 year placement with Voluntary Service Overseas (VSO), and later in 2006-2009 I undertook a 3 year distance learning MSc in climate change and sustainability. My background is as a structural engineer, before moving to work in corporate sustainability, especially using a consumption-based approach to carbon accounting. In 2012 I left my consulting background to undertake a full-time PHD in Ecological Economics at the University of Leeds, which I completed in 2016.

Research interests

My research is focussed on studying macroeconomic energy-economy interactions, through primarily the lens of exergy analysis. Exergy is considered as 'available energy', and enables the study of the energy conversion chain from primary to final to useful stages - where it is lost in exchange for energy services.

My work spans various energy-economy fields, including societal exergy analysis, energy rebound, the role of (thermodynamic) energy efficiency on economic growth; energy return on investment (EROI).  I work within an network of international researchers in the field of exergy economics, and act as one of the conveners of this network, which has an outward facing website here: https://exergyeconomics.wordpress.com/

My current programme of work (2018-2023) follows the award of a 5 year Early Career EPSRC Fellowship entitled  "Applying thermodynamic laws to the energy-GDP decoupling problem". My fellowship applies thermodynamic laws to examine a national and global problem: how can we decouple primary energy use from economic growth? - i.e reduce energy consumption to help mitigate greenhouse gas emissions, whilst allowing economies to grow to improve citizen well-being. However, despite wide-scale energy efficiency policies and investment, at the global level no absolute decoupling (energy down, GDP up) has occurred. The vision for the fellowship is a better understanding the role of energy efficiency and energy rebound in the energy-GDP relationship, thereby improving the evidence base for primary energy reduction policies. Studying exergy flows through an economy enables thermodynamic-based quantification of both aggregate energy (exergy) efficiency and energy rebound. The aim of my project is to build on momentum and insights from recent research – including my own – to complete world leading exergy-based research into the energy-GDP decoupling problem within an expanded international research network.

Three key research questions are studied:

  • Q1. What is the relationship between energy efficiency and energy rebound?
  • Q2. How much primary energy will we need in the future to meet our energy service demands?
  • Q3. To what extent can we decouple primary energy use from GDP
