The Primary Energy Fallacy: Why Electrification Changes Everything, EP. 293

This week on Energy Unplugged, Richard Howard, Aurora Energy Research’s Global Research Director, is joined by Jan Rosenow, Energy Programme Lead, Jackson Senior Research Fellow and Professor of Energy & Climate Policy at Oxford University.

Drawing on his latest research, Jan explores the concept of the “primary energy fallacy” - the mistaken assumption that the clean energy transition requires replacing today’s fossil fuel energy inputs on a one-for-one basis with clean power. Richard and Jan discuss why this view overstates the scale of the challenge, and how electrification fundamentally changes the equation by delivering the same energy services with far less energy input.

The conversation examines how electrification is reshaping transport, buildings, and industry, why electric technologies are often dramatically more efficient than their fossil-fuel counterparts, and what this means for energy demand, system planning, and decarbonisation strategies. From electric vehicles and heat pumps to industrial process heat and thermal storage, the discussion explores the opportunities and barriers that will determine the pace of electrification over the coming decades.

You will learn about:

• Why the “primary energy fallacy” may be causing us to overestimate the scale of the energy transition.

• How electrification can deliver the same energy services with significantly less energy input.

• Why transport is electrifying rapidly, while buildings and industry continue to face economic and policy barriers.

• How technologies such as heat pumps, thermal batteries, and electric process heating are expanding the scope for electrification.

• What governments and energy markets need to do to make electricity the default choice across the economy.
