Research summary

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

Teaching summary

Steve is the lead for the module 'Introduction to Modelling, Methods and Scenarios' (BENV0012) on the MSc Economics and Policy of Energy and the Environment.

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.
