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. 00:00 A little error... 03:22 Fragile Fuel Systems and Global Crises 05:53 The Myth of North Sea Energy Security 07:44 The Colossal Scale of Global Oil Consumption 08:44 The 20/80 Rule: Why Electricity Isn't Everything 10:41 Efficiency: Why Electrification Halves Energy Use 12:47 China’s Solar Revolution and Coal Reality 15:52 The Mindset of the New Generation of Engineers 18:51 Market Tipping Points: Cheaper, Faster, Lighter 22:26 Data Centers vs. EV Grid Impact 28:04 Raw Materials, Lithium Mining, and Circular Economies 34:02 SMRs, Fusion, and Carbon Capture: The Reality Check 41:41 Energiewende and Global Energy Access 48:14 The Next Big Thing: Industrial Heat Batteries 52:40 Domestic Advice: Batteries vs. Solar Why not come and join us at our next Everything Electric expo: https://everythingelectric.show Check out our sister channel Everything Electric CARS: https://www.youtube.com/@fullychargedshow Support our StopBurningStuff campaign: https://www.patreon.com/STOPBurningStuff Become an Everything Electric Patreon: https://www.patreon.com/fullychargedshow Become a YouTube member: use JOIN button above Buy the Fully Charged Guide to Electric Vehicles & Clean Energy : https://buff.ly/2GybGt0 Subscribe for episode alerts and the Everything Electric newsletter: https://fullycharged.show/zap-sign-up/ Visit: https://FullyCharged.Show Find us on X: https://x.com/Everyth1ngElec Follow us on Instagram: https://instagram.com/officialeverythingelectric To partner, exhibit or sponsor at our award-winning expos email: commercial@fullycharged.show EE NORTH (Harrogate) - 8th & 9th May 2026 EE WEST (Cheltenham) - 12th & 13th June 2026 EE GREATER LONDON (Twickenham) - 11th & 12th Sept 2026 EE SYDNEY - Sydney Olympic Park - 18th - 20th Sept 2026 #fullychargedshow #everythingelectricshow #homeenergy #cleanenergy #battery #electriccars #electric-vehicles-uk
