What They Said

“I've always been rather skeptical of target metrics. They usually get adopted by politicians who are no longer in power when these targets kick in, and then they're quietly abandoned.” — Jan Rosenow, Zero: The Climate Race

Still on the proposed 35%-by-2035 electrification target, Rosenow grants the symbolic value of such targets but says he would not be too obsessed with them.

…this very clearly: that the expectation is that in most parts of the world, the cheapest way of generating electricity will be a combination of renewables, mainly solar and wind plus storage, even factoring in storage at the same time. It will be cheaper than building new gas-fired power stations.

Akshat Rathi

…electricity by 2035, from about 20-ish percentage. We'll come to the sort of final energy question later, but there is clearly an increase in electricity share of whatever energy is being consumed. Do you think that target should include that the electrification needs to come from clean sources?

Jan Rosenow

…there before. So, yeah, it is the target as it stands is not particularly helpful when it comes to understanding how you deliver on that target and what the benefits will be. I would still say having, you know, there's a huge symbolic value of having an electrification target because it does focus people's minds and it leads to a conversation about electrification. And that's a good thing. But I've always been rather skeptical of target metrics. They usually get adopted by politicians who are no longer in power when these targets kick in, and then they're quietly abandoned. So, I think targets are useful to focus minds and drive the discussion in a certain direction, but I wouldn't be too obsessed with them either.

Akshat Rathi

I suppose you could say the same thing about the Paris Agreement, where there are clear targets about keeping global warming below two degrees Celsius and preferably below 1.5 degrees Celsius. It focuses the mind to actually act on it, even though there is a very real risk that we may even blow…

Jan Rosenow

I think a good way of maybe visualizing this in your mind is to think about the energy flow that we see in the world. And a lot of people have drawn Sankey diagrams. That's a sort of technical term. Captain Sankey, he was, I think, an Irish engineer who wanted to understand how efficient steam…

Akshat Rathi

And so one way to think about it is from the perspective of oil. Like drilling just crude oil is primary energy. Then having refined products in petrol, diesel, or jet fuel is final energy. And then if the fuel is used for motion most of the time, that motion itself, the outcome of that motion, how…

“Without electricity we would not have a functioning energy system, and that includes the fossil fuel energy system. Your gas boiler needs electricity to run. When you get your car fueled at the pump, there's an electric pump that pumps the petrol or the diesel into your car. The water system would fail. The whole society depends on electricity.” — Jan Rosenow, Zero: The Climate Race

The host raised the argument that an electrified economy is more exposed to cyberattacks and blackouts. Rosenow says the current fossil system already depends on the grid, so the risk is not new, though he calls it serious and says it needs an honest discussion.

…the network, connect people? Or is it perhaps to connect new devices to make sure we can go through this transition? And then the question becomes, how do we do that in the most cost-effective way that lowers cost for consumers and that gets us to where we need to get in the fastest possible way?

Akshat Rathi

…digital network, so really open to cyber attacks. And of course, electricity is hard to store. Even if we have batteries, electric ones, or heat batteries, it's just not possible to store energy as we can in, say, an oil reserve or a gas reserve. How do you make an electrified system a secure one?

Jan Rosenow

This is a great question. Let me perhaps comment briefly on the key competing goals of the transition, which have often been framed as the energy trilemma, where you have affordability. have reliability of supply and you have sustainability and I think increasingly those three goals are not in conflict necessarily and there are definitely sweet spots where you can deploy a technology find a solution that delivers simultaneously on all three having said that of course if we electrify we have to think about resilience and we have seen in Berlin for example I think it was last winter that after a deliberate attack on I think it was a substation in the south of Berlin there's been a blackout for extended periods of time and you know other things similar things may happen maybe cyber attacks what I would say though is that without electricity we would not have a functioning energy system that includes the fossil fuel energy system so when you think about your gas boiler that needs electricity to run when you think about getting your car fueled at the pump there's an electric pump that pumps up the the the petrol or the diesel into…

Akshat Rathi

it's already true that the electric system is core to global economics to any country's economics more than any other type of fuel has been you know the oil shocks of the 1970s had a devastating effect on global economies while the oil shock of 2022 or 2026 hasn't quite had the same economic impact…

Jan Rosenow

and there are also examples of cyber attacks or data breaches when it comes to fossil fuel infrastructure you know the examples of pipelines suddenly not working anymore and and and it's not just limited to the electricity sector um but i wouldn't you know i wouldn't want to just brush that away…

Akshat Rathi

let's take uh the framing that you talked about earlier which is more and more countries will use electricity some of these countries are already on that cusp many call them electrostates there is an advantage that comes from it which is if you are generating that electricity at home through…

“We over-tax electricity compared to fossil fuels. We essentially have higher tax rates and levies and policy costs on the electricity bill. … And fossil fuels get a bit of a free ride.” — Jan Rosenow, Zero: The Climate Race

The host asked what governments can do now to make electricity cheaper so people see the savings from electrifying. Taxation is the first lever Rosenow names, ahead of network costs and gas-set wholesale prices.

…take investment at scale. That's why Eberdrola has committed two-thirds of its capex toward building smarter, more resilient networks. Because generating more electricity is only part of the challenge. As demand grows, the future needs a grid capable of delivering it. Find out more at eBadrola.com.

Akshat Rathi

…it may not be. But getting to that future requires you to have political buy-in from people to electrify, which at the cost that prices are today doesn't seem viable. What can governments really do right now to make electricity cheap and show the savings that may come from electrification today?

Jan Rosenow

There's a number of things. Let me start perhaps with taxation, because that's kind of an obvious area where governments can quite quickly decide to lower the cost of electricity. We know that in many countries, we over-tax electricity compared to fossil fuels. We essentially have higher tax rates and levies policy costs on electricity bill. That's also the case in the UK, but elsewhere as well. And fossil fuels get a bit of a free ride. So that rebalancing of taxation and levies can, in some cases, make a really, really significant difference to what the price of electricity is. Then you have things like network costs. That's a bit more tricky because we are paying for infrastructure that we may need for the next 10, 20, 30 years, but we need to build it now in anticipation of a rising electricity demand. So how are you…

Akshat Rathi

One aspect of this, which is sort of playing out with the Iran war and where fossil fuel prices are, sure, many consumers have looked to electric options, but a lot of governments' initial reaction has been to find other sources of fossil fuels or to subsidize energy right now because the prices…

Jan Rosenow

I think there's always a short-term scramble to solve the crisis. And that's understandable. I mean, if you're in government and you see prices shoot up by maybe three, four, five, or 10 times even in 2022, that's what we've seen in the gas markets in Europe. You have to react. And you can't just…

Akshat Rathi

In terms of Europe, the biggest share of emissions tends to be heating homes and buildings with natural gas. I know you have looked at electrification of heating very closely. The obvious solution is heat pumps, but there are success stories and then there are failures across Europe when you look…

“What is a missed opportunity is when governments then stop there and only do the short-term fix, because that's sticking plaster. It's dealing with the symptoms, but it's not curing the illness. And the illness is the over-reliance on fossil fuel imports and an exposure to these very volatile markets.” — Jan Rosenow, Zero: The Climate Race

The host asked why governments answer an energy price shock with subsidies and new fossil supply instead of electrifying. Rosenow says the emergency response is understandable but wrong if it stops there.

…with batteries, with renewables. But we still have places like Italy, for example, or the UK, where gas is a very dominant factor in the wholesale market. So reducing that by speeding up the deployment of storage, speeding up the deployment of renewables will also help bring down prices.

Akshat Rathi

…more fossil fuels for 10, 15, if it's a new industrial build, maybe for decades to come. You've worked with governments, advised them, you've showed why an electrification system is a better one. And yet this urgency that we must electrify hasn't quite sunk in with most governments. Why is that?

Jan Rosenow

I think there's always a short-term scramble to solve the crisis. And that's understandable. I mean, if you're in government and you see prices shoot up by maybe three, four, five, or 10 times even in 2022, that's what we've seen in the gas markets in Europe. You have to react. And you can't just say, oh, over the next 10 years, we're going to change the energy system. You have to do something in that very moment. And in this case, it was making sure we have enough gas for the winter that was coming. We already saw there was a cut in gas supply from Russia in, I think it started in September or August 2021. And you have to react to that and make sure there is enough energy available, right? At the same time, when prices rise, you've got to protect people from those price rises. So I totally understand why governments have acted in that way. What is a missed opportunity, though, is when governments then stop there and only do the short-term fix, because that's sticking plaster. It's dealing with the symptoms, but it's not curing the illness. And the illness is the over-reliance on…

Akshat Rathi

In terms of Europe, the biggest share of emissions tends to be heating homes and buildings with natural gas. I know you have looked at electrification of heating very closely. The obvious solution is heat pumps, but there are success stories and then there are failures across Europe when you look…

Jan Rosenow

Yeah, I think we know what the ingredients are and it's really quite simple. One of which we already talked about is electricity price. So we know where the electricity to gas price ratio is low. So by low, I mean at least below three, ideally lower than that. People will start buying heat pumps.…

Akshat Rathi

So one unit of electricity should be a third of the price of gas? No.

“I just don't see how in 10 years' time, or even now, there's a strong business case for building new fossil generation. And research shows this very clearly: in most parts of the world, the cheapest way of generating electricity will be solar and wind plus storage, even factoring in storage. It will be cheaper than building new gas-fired power stations.” — Jan Rosenow, Zero: The Climate Race

The host pointed out that the US data center and AI boom is expected to raise gas burn in the short term, and asked whether that holds in the long run. Rosenow says the economics have already shifted against new gas plants.

…There's still some fossil in there, but it's tiny. I think 90% plus of all capacity being built is renewable. So I would be surprised if the additional electricity demand that we're layering on top would be provided with fossil fuels. I think most of it will be served with renewable energy.

Akshat Rathi

…like the United States, where we are seeing a boom because of artificial intelligence and all the data centers that need to be powered, there is clear indication that gas burn is going to increase in the short term. But you think, even in the US, in the long term, this is not going to be the case.

Jan Rosenow

Yes, and that's specifically because the fundamental economics have changed in a way where I just don't see how in 10 years' time, or even now, there's a strong business case for building new fossil generation. And research shows this very clearly: that the expectation is that in most parts of the world, the cheapest way of generating electricity will be a combination of renewables, mainly solar and wind plus storage, even factoring in storage at the same time. It will be cheaper than building new gas-fired power stations.

Akshat Rathi

So, let's take this goal that many countries are going to talk about at COP31, which is to increase the final energy of global consumption to 35% for electricity by 2035, from about 20-ish percentage. We'll come to the sort of final energy question later, but there is clearly an increase in…

Jan Rosenow

I mean, one of the problems with such targets is always that you could achieve them in a way that actually isn't particularly helpful. So, let's, you mentioned data centers before, right? You could just build loads of data centers, which drives up the electrification rate. Is that a good thing?…

Akshat Rathi

I suppose you could say the same thing about the Paris Agreement, where there are clear targets about keeping global warming below two degrees Celsius and preferably below 1.5 degrees Celsius. It focuses the mind to actually act on it, even though there is a very real risk that we may even blow…

“You could just build loads of data centers, which drives up the electrification rate. Is that a good thing? … It's not a good thing from replacing, displacing fossil fuel consumption in industry, buildings, transport, because it's just adding electricity demand that wasn't there before.” — Jan Rosenow, Zero: The Climate Race

The host asked whether the COP31 goal of raising electricity's share of final energy to 35% by 2035 should require that the power be clean. Rosenow answers that the headline metric can be met in unhelpful ways, such as an AI data center boom that adds new demand without displacing any fossil fuel.
