Energy transition is often depicted as a choice between different supply-side technologies such as wind or solar versus oil and coal. However, the demand side of the energy transition — focusing on efficiency improvements to buildings, adopting walking and biking over driving, and electrifying consumer appliances — deserves just as much attention. Would you believe that widespread adoption of demand-side measures like these could cut the UK’s energy demand in half without sacrificing services or quality of life? That’s one of the key insights our guest in this episode has to share. Nick Eyre is one of the most well-informed experts on the demand side of the energy transition. He is Professor of Energy and Climate Policy, and Senior Research Fellow in Energy, at the Environmental Change Institute at Oxford University in England. He serves as the Director of the Centre for Research into Energy Demand Solutions, which is UK Research and Innovation’s (UKRI's) primary investment in energy use research. He is also a Co-Director of the Oxford Martin Programme on Integrating Renewable Energy, which is undertaking research on the combined, technical, economic, social and policy issues in moving to electricity systems with very high levels of variable renewables. For the past five years, Nick has led a comprehensive project involving hundreds of researchers to review nearly 500 publications on the demand side of energy. This project concluded at the end of 2023, and he joins us today to share its key insights. He’ll help us understand the most important demand-side decarbonization strategies in 2024, and what we can do to accelerate their deployment. It’s a really comprehensive, yet very accessible (and not too geeky) discussion that offers at least a few practical insights that all of our listeners could readily consider applying in their own lives.
