Steve Pye is an Associate Professor of Energy Systems
at the UCL Energy Institute, University College London (UCL). Steve has 15
years’ research experience on energy and climate modelling and policy analysis. His
research concerns the challenge of energy system decarbonisation, using
different whole system energy modelling approaches, with a particular focus on
scenario modelling of national and global low carbon pathways, uncertainty
assessment, and the equity and health dimensions of energy transitions. Steve’s
research track record is reflected in over 40 peer review journal articles and
numerous technical reports and papers. He has led multiple research projects for
a range of funders including the Energy Technologies Institute, the UK
Committee on Climate Change, and the European Commission. Most recently, he has
been a researcher co-investigator on the CREDS Heat Decarbonisation Challenge,
focused on how models consider features of Energy System Architecture. Steve
has also been involved in a range of major international initiatives, including
the Deep Decarbonisation Pathways
Initiative, Lancet
Countdown, and the UNEP
Production Gap report.




Steve's research focus on the use of energy-economic models to explore transition pathways under stringent climate targets, both at the UK and global scales. Of particular interest are the following topics in relation to energy sector decarbonisation (as reflected in recent publication) -
* Incorporating uncertainty into decision making
* Determining the role of fossil fuels
* Social equity considerations in modelling transitions
* Net zero emission pathways
