The project 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
