The electrification imperative: the power of electrofficiency

Much of the debate about the energy transition focuses on how to produce enough clean energy to replace fossil fuels. But electrification offers another fundamental advantage: it can dramatically reduce the amount of energy needed in the first place. Electric technologies such as heat pumps and electric vehicles can provide the same services using substantially less energy than the fossil-fuel technologies they replace. This combination of electrification and greater efficiency is known as electrofficiency. In this talk, Professor Jan Rosenow will explore why electrofficiency matters for the transition away from fossil fuels and what it means for the future of the energy system. He will examine the opportunities for direct electrification across buildings, transport and industry, how widespread electrification could reshape overall energy demand, and where other solutions may still be required. The talk will also consider the implications for electricity grids and infrastructure, the policy changes needed to accelerate deployment, and the barriers standing in the way of faster electrification. Professor Rosenow will also introduce the new Oxford Martin Electrification Accelerator, which he directs, and explain how it aims to bring together research, policy and practice to overcome these barriers and accelerate the transition towards a cleaner, more efficient and increasingly electric energy system.
