I have been researching and teaching energy policy, low-carbon technologies, decentralized energy systems, and energy modeling for more than 25 years. I have been a Professor of Energy and Environmental Systems at the Centre for Environment and Sustainability (CES), University of Surrey, UK since 2007. From July 2019, I have worked part-time at Surrey as an independent consultant/researcher for 80% of my time. My consulting focus is now on modern energy cooking services, a 39.8 million GBP program funded by DfID and led by Loughborough University, GAMOS, and the World Bank’s Energy Sector Management Assistance Program (ESMAP). MECS aims to accelerate the transition from biomass (wood/charcoal)-based cooking to modern, clean, low carbon, energy-efficient alternative methods that utilize renewable sources of electricity such as solar photovoltaic systems and biogas.
