The Nordics understood early on that fossil fuel dependency comes with a price: price volatility. They moved full speed ahead on electrification of heat starting decades ago. Today fossil fuel use for heating has dramatically fallen. https://t.co/aFYP7K8RAg https://t.co/k1Gz1747qb
Heat pumps are a key lever to become independent from fossil fuel imports. I'm quoted in this piece by @KarlMathiesen @politico on what installing a heat pump in the UK is actually like for consumers. TL;DR: There is some room for...
Some countries are better positioned to weather this energy crisis than they would have been just a few years ago. That's because of the rapid growth of renewable energy, battery systems and electric vehicles. NPR interviewed me for this excellent piece:...
Here we are again. In 2022–23 Europe spent €800bn subsidising fossil fuels to keep energy bills down. Imported fossil fuels mean volatile prices. The real solution is not new suppliers but a shift to clean energy. https://t.co/c6n2Q03PO1
Good news on a Sunday and in times of an energy crisis: the number of heat pump installations in the UK last year was over 4x higher than in 2020 new government figures confirm. https://t.co/CsxB2ff5P9
Why oil shocks still hit everything we buy. “We should be very concerned, the longer the conflict lasts, the more prices will rise and ripple through the economy.” From petrol to plastics, another fossil fuel crisis shows how exposed economies remain...
Heat pumps are the most efficient heating technology ever invented. They harvest and compress pre existing heat in the air, ground or water and transport it where it is needed. That energy is all around us. And it does not have to...
Solar does not care about the Strait of Hormuz. Oil flows through chokepoints. Solar follows a learning curve. Great piece @azeem https://t.co/QqddYuyh9a https://t.co/4dYcRUXdI4
The impact of the war in the Middle East on energy: We should fix the roof when the sun is shining not when there's a thunderstorm. Only when we shift energy demand from burning fuels to using electricity from clean power...
Energy policy déjà vu in Europe. Oil reserve release. Gas price cap debate. State aid on the table. The toolkit looks like 2022 because fossil fuel dependence remains. Renewables and electrification reduce exposure. Crisis management does not. https://t.co/PhWMbn21b8
I was interviewed by @AlJazeera on impacts of Middle East crisis on energy markets. We discussed Europe’s structural vulnerability due to fossil fuel imports, broader economic effects of energy price volatility & why this moment should sharpen focus on the energy...
Reaching net zero by 2050 is often framed as a cost burden. The UK Climate Change Committee’s latest analysis suggests the opposite. The real risk is fossil fuel dependency. https://t.co/m4AZokLzFS
Universities provide an interesting testbed for adopting innovative technologies. Here is Princeton using what appears to be a very large ground source heat pump with 2,000 (!) boreholes. https://t.co/SowKV9ivJe
Heating oil prices in the UK have trebled in a week. 2 million homes, no price cap protection, no warning. Heat pumps + solar are multiple times more efficient, don’t require an oil tank and oil deliveries and are an insurance...
Another Monday morning, more energy market turbulence. After fossil fuel prices stabilised somewhat towards end of last week they are reaching new highs. Renewable electricity does not as the sun & the wind don’t care much for what happens in...
Rising energy prices are pushing up inflation, especially in economies dependent on imported fossil fuels. The durable solution is structural: improve efficiency, accelerate electrification and scale up renewables. Energy policy is economic policy. https://t.co/hmcAVJFLOT
Brace yourself - energy prices may well rise quite a bit higher than last week. https://t.co/PwzU61UTCt
Geopolitical turmoil in the Middle East once again shows that reliance on volatile oil and gas exposes economies to price shocks. Renewables, electrification and storage offer more stable long term energy costs and stronger energy security. https://t.co/7ejmElNKxi
What will be impact of the conflict in the Middle East be on energy bills? What can we do to avoid being so exposed to international fossil fuel price volatility? I was asked these and other questions by LBC News....
Heat pump sales rose 11% in 2025 across 16 European countries, with 2.63 million units sold. Twelve countries saw growth, largely where subsidy schemes were stabilised and electricity costs addressed. Policy certainty and energy levies & taxation are proving decisive. https://t.co/hvp6WLgpb3
The Middle East conflict is stress testing global energy. Bloomberg sees oil at $108 in a severe escalation. We have seen this before. The difference now is that solar and batteries are more cost competitive. Every fossil fuel spike strengthens the...
Grid investment is rising fast. BloombergNEF reports record spending in 2025 of 470 to 483 billion US dollars, up 17 percent on 2024. This reflects structural change: more renewables, electrified transport & heating + rising demand from data centres. https://t.co/4l1nzdMy3j
Europe remains one of the economies most exposed to volatility in global energy markets. The EU still depends on imported fossil fuels for close to 60% of its energy needs. Among large economies, only Japan and South Korea have higher levels of...
📌 A reminder: Most of the gas Europe imports is used for heat - to warm our buildings and to provide process heat in industry. Only around 20% of gas is used to generate electricity. https://t.co/31yV3zzXKL
What does the potentially emerging energy crisis mean for Europe? Yesterday I was in a media briefing with 75 journalists. Here is a snippet of what I told them. https://t.co/3dT441Yllq
Gas prices jumped again this morning and are on track to double - a stark reminder of our exposure to fossil fuel volatility. The real solution isn’t more drilling, but moving away from combustion: electrify, use renewable power, and boost energy...
Just last week the German government gutted the heating law which was supposed to drive a transition away from gas. The timing could not have been worse: Gas prices are up 50% today & this crisis could worsen significantly. This will...
Gas prices up by around 50% today. A painful reminder that relying on imported fossil fuels is a risky strategy. https://t.co/uXkWNMXbeQ
Europe is once again reminded of a structural vulnerability. As I told @politico: “The fact is still that Europe imports most of its energy from other countries. And I think events like this just highlight how problematic, how risky that is...
China’s latest energy data offers a signal worth paying attention to. In 2025, emissions from energy and industry fell by 0.3%, modest, but notable, even as total energy consumption rose by 3.5%. The key driver? A continued surge in solar...
Despite significant federal headwinds, US renewables just had a record year. Notably, 93% of new generation capacity expected to be added to the US grid this year is projected to come from wind, solar and batteries. https://t.co/XSZdvMLYWX
Europe’s energy transition is well underway but it is far from uniform. In 25 European countries, non-fossil fuel sources now generate the majority of electricity, a clear sign of how deeply clean power has penetrated the system. https://t.co/NjTmx157Rn
🎙️NEW PODCAST: Energy policy is increasingly industrial policy. Why? How does it impact on companies and on the energy transition? What are the opportunities and risks that arise? I was interviewed by the @EYnews Better Finance: CFO Insights podcast. Links in comments. https://t.co/BmLTovVV7F
🔥 LIVESTREAM TODAY 4pm UK 🎙 Redefining Energy @OrielOxford Is the energy transition accelerating, stalling or being rewritten by politics? Join me & @MegaWattXinfo for an unscripted, audience-driven debate. 👉 https://t.co/2bbMhmCKed https://t.co/JXpJbINxtA
Denmark is a poster child of the energy transition. Yesterday I gave a keynote at Green Summit 2026. One message stood out: energy policy is industrial policy & increasingly geopolitics. The next phase isn’t about targets, but competitiveness, resilience & execution at...
The US risk drifting toward petrostate economics. Regulatory rollbacks and clean energy policy U-turns aren’t just about climate — they affect jobs, industrial competitiveness, health and investment certainty. https://t.co/6Jn5YrWN68
GOOD NEWS: The world’s largest steam-producing heat pump is now online in Finland, delivering 12 MW of superheated steam from waste heat and CO₂-free electricity. Proof that industrial heat can be electrified at scale. https://t.co/3UucWRcOJI https://t.co/IfhpiYqPOm
10 years ago I worked with Polish colleagues to phase out coal heating. Clean heating policies worked – Poland’s air is cleaner today. Clear rules and support for households cut pollution and saved thousands of lives. https://t.co/qiuzuJE4dD https://t.co/HL0kLyy8KG
We tend to think of batteries as the ones in our phones. But the real shift is happening at grid scale. Utility-scale “mega batteries” now have hundreds of millions of times the capacity of smartphone battery. Costs down ~40% since 2024 Capacity in...
This is why electrification means more energy security: In 2024, ~81% of EU electricity came from locally sourced fuels (57% excluding nuclear). Just 19% relied on imported fossil fuels. Fossil fuels are mostly imported. Source @ember_energy https://t.co/vHX1LedgmM
I stopped counting but there are now close to 70 independent studies all coming to similar conclusion: “Hydrogen boilers […] remain economically unviable.” This is what this paper which I had not yet read found comparing a range of heating...
EU fossil imports met 58% of energy demand in 2023 - near pre-crisis levels - leaving consumers exposed to price shocks. Far above China (24%) & India (37%); only Japan (84%) & S. Korea (80%) rely more on imports. Graph: @ember_energy...
"Reducing reliance on fossil fuels looks like Europe’s best shot at saving its domestic manufacturing and stopping other governments from pushing it around." Outstanding article in The Wall Street Journal. https://t.co/XbYr95c2nK https://t.co/rUtmRPTUST
You cannot make this up. US administration is directing the Department of Defense to buy coal power and spending $175m to keep ageing coal plants running. Coal plants average 44 years old. Many are costly and prone to outages. Markets, not ideology...
Most people don’t know this: Heat pumps REDUCE gas consumption even if running 100% on electricity from a gas fired power plant. More here in my piece for @CarbonBrief 👇 https://t.co/rKlRE0ug1S https://t.co/DTnKDp9lZp
A reminder: ICE vehicles waste a whopping 80% of energy in their fuel. EVs are propelled by entirely different mechanisms. Energy enters the vehicle as electricity, which directly powers the drivetrain making it 3-4x more efficient. https://t.co/bvBDqWFEwj
“I think Greenland was a wake-up call. There is more talk [in Brussels] about replacing one dependency with another.” This is what I told the Wall Street Journal about Europe’s increasing dependence on US LNG following the end of Russian...
Using hydrogen as a fuel to replace natural gas has been strongly promoted by vested interest groups. Many including myself raised serious concerns about scalability, cost and efficiency. The more time passes, the more it looks like those concerns were...
