Summary

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.

Hello and welcome to another episode of the Everything Electric podcast.

0:15.9

Little bit different this week.

0:17.8

This is definitely an audio podcast.

0:25.2

You can put that lack of a video feed down to the interviewer on this particular episode. I'm not going to name that interviewer. I don't want to

0:31.9

shame them. They're already shamed enough as it is. But anyway, the important thing is that the audio is brilliant and the audio works and you can hear,

0:40.3

because that's really what you need to do.

0:42.1

You need to be able to hear what we were talking about.

0:44.1

Oh, that's just giving it away that I am the interviewer who screwed up the video.

0:49.2

I forgot to press record.

0:50.9

Anyway, who I'm talking to for this episode, it has been on the show before,

0:57.1

but a while ago, about four or five years ago, extraordinary man, really, you know,

1:02.9

if you want to find someone that genuinely has a deep, profound understanding of the energy

1:08.7

transition of the impact of burning 105 million barrels

1:14.1

of oil a day. You know, all those basic things in the background of the fully charged show

1:20.4

and everything electric and everything we've been doing for the last 16 years, he's like right

1:26.1

at the front. So today we'll be talking to Professor Jan Rosanoe.

1:31.1

And I just want to read out because I'm not going to remember this. His, who he is.

1:35.4

So he, Jan is the professor of energy and climate policy at the Environmental Change Institute and the Jackson Senior Research Fellow at Oriel College Oxford, which which is where we recorded it and it looked beautiful and some stupid idiot didn't press record.

1:50.0

Anyway, moving on. He is also a senior associate at the Cambridge Institute for Sustainability Leadership at the University of Cambridge and an affiliate faculty at the University of Sussex.

1:59.0

He's kind of quite well connected. So I'm not

2:01.9

going to waffle on. I'm just going to ask you, please do check out the show notes here, which

2:06.6

will also include a link to our live events. One of them is coming up fairly soon in Harrogate,
