Dr. Roger BentleyDr. Roger Bentley, University of Reading

Dr. Bentley is a Visiting Research Fellow at the University of Reading’s Department of Cybernetics. His research areas include global hydrocarbon depletion, solar energy, and broader energy issues. He was a member of the University of Reading’s ad hoc ‘Oil Resources Group’ which has given presentations on oil depletion to governments, industry, research institutions and academia.

In 2001/02, Dr. Bentley was Co-ordinator of the Oil Depletion Analysis Centre, London. Other positions held include Head of Research, Whitfield Solar Ltd.; Senior Research Fellow, University of Reading; Modelling Analyst, Thames Water Utilities; and Financial Analyst, Esso Chemicals.

Dr. Bentley has published some 40 academic papers.


Dr. Euan MearnsDr. Euan Mearns, University of Aberdeen

Dr. Mearns is an Honorary Research Fellow in the School of Earth Sciences at the University of Aberdeen. He worked as a researcher at The University of Oslo and then The Norwegian Institute for Energy Technology for a total of 8 years. In 1991 he set up a company in Aberdeen, Scotland providing isotope analyses to the international oil industry. His company worked for over 60 exploration and production companies world wide but eventually ran out of reservoirs to characterise and the company was sold in 2001. Euan has been at the University of Aberdeen since 2009. His main interests lie in understanding energy systems, forecasting, and energy policy.





Rembrandt KoppelaarRembrandt Koppelaar, Institute for Integrated Economic Research | Imperial College London

Rembrandt Koppelaar has been a Research Associate at the Swiss Institute for Integrated Economic Research (IIER) since 2010, where he works on modelling of resource availability and the effects of resource cost changes on economic growth. Since June 2012 he has been based at Imperial College’s Centre for Environmental Policy, where he studies technological change of energy and resource systems. His work there is part of a joint Imperial College and IIER project to develop an integrated economic computer model of a city and its environment, meant to analyse how more stable and cyclical resource use environments can emerge. He is author of the book De Permanente Oliecrisis, in which he discusses the end of cheap oil and its consequences (Dutch language, Nieuw Amsterdam publishers, 2008). Rembrandt holds a MSc degree in economics from Wageningen University, the Netherlands.

Chris VernonChris Vernon, University of Bristol | Centre for Sustainable Energy (CSE)

Chris Vernon is currently working towards a Ph.D. in glaciology focusing on the Greenland ice sheet at the Bristol Glaciology Centre, University of Bristol. He holds masters degrees in Computational Physics and Earth System Science from York and Bristol and has studied energy systems and environmental decision making with the Open University. Chris has 10 years’ engineering experience in the field of cellular telecoms, specialising in radio network architecture and off-grid power systems in emerging markets. He is also a trustee at the Centre for Sustainable Energy, where he works on the twin challenges of rising energy costs and climate change, and is an editor at The Oil Drum. He lives in Bristol.




Dr. Jelte HarnmeijerDr. Jelte Harnmeijer, University of Edinburgh | The Sustainable Community Energy Network (SCENE)

Jelte has 10 years’ experience working in both the developed and developing world as a scientist and programme manager. He studied and worked at the University of Cape Town, South Africa; the University of Sydney, Australia; the University of Washington, U.S.A.; and the University of Edinburgh, Scotland. Amongst other things, he spent seven years studying the world’s oldest oil droplets through a NASA grant. Jelte continues to contribute to carbon cycling and climate research, most recently through an article in Nature Magazine. Jelte is interested in the consequences of fuel supply constraints and climate change on economic- and agricultural systems, and has offered courses, workshops and seminars on these issues at universities and public fora alike. He managed a productive agro-ecological farm in California’s largest Indian reservation in 2010. More recently, he co-founded an Edinburgh-based Social Enterprise called SCENE that looks to offer global finance solutions for Community Renewables projects.


Simon Ratcliffe, UK Department for International Development (DFID)

Simon has an M.Sc. from University College London and an MBA from Warwick University.  He works as an Energy Advisor at the UK’s Department for International Development.  He is concerned about the impact of resource scarcity on developing countries, energy scarcity in particular.  He is cognisant of the fact that energy is the key element in economic development.  He is keen to find alternative energy pathways for developing countries in order to reduce their dependence on fossil fuels.  He is one of the authors of Scenarios 2019 – Fragmentation or Renaissance:  The inter-connections between oil depletion, climate change and global financial imbalances for the South African Presidency’s Scenario Planning in 2007.  He is also one of the authors of the Oil and Transport Reference Report for the National Transportation Masterplan for the South African Department of Transport in 2009.  He is a member of the organising committee of the Global Energy Systems Conference in his personal capacity.
