Electrification Could Cut Global Energy Use in Half

In this episode of the Everything Electric PODCAST, Robert Llewellyn sits down with Professor Jan Rosenow, Professor of Energy and Climate Policy at Oxford University, to reveal why electricity currently only tells 20% of the global energy story.

They delve into tackling the “hidden 80%”, the mobility and heating sectors still dominated by fossil fuels; and explore why our current system is “astonishingly inefficient,” wasting two-thirds of all energy inputs as heat. Jan explains how shifting to electrification at scale could cut total global energy demand in half and tackles the biggest myths and milestones of the transition:

  • The Grid Threat: Why data centers pose a more significant regional challenge to the grid than 100 million electric vehicles.
  • Critical Materials: Is the world really running out of lithium, or are we entering an era of “urban mining” where 95-97% of battery materials can be recycled?
  • The China Factor: A look at the “mind-blowing” scale of solar adoption in China and the declining utilization of their coal plants.
  • Beyond Climate: Why electrification is now a primary lever for energy security and economic resilience in a volatile world.

From the efficiency of heat pumps to the emergence of industrial heat batteries , this episode connects the dots on what the next phase of the energy transition really looks like.
