1/ Published today in @natcomms.nature.com: our analysis on long-duration electricity storage needs for coping with #Dunkelflaute events in 🇪🇺 . Joint work with my stellar @diw.de colleagues @kittelmartin.bsky.social (lead) and @aroth.bsky.social 🎉https://www.nature.com/articles/s41467-026-72681-5

1/ 🔌🚗 Neue Zahlen zu Elektroautos: ▶️ Im April 2026 war gut jedes vierte neu zugelassene Auto in Deutschland rein batterieelektrisch (25,8%). ▶️ Damit hat sich der positive Trend der letzten Monate fortgesetzt. ▶️ Das verbesserte Modellangebot und die neuen Kaufprämien dürften sich positiv auswirken.

It has been a solid week of European natural gas filling. Daily rates are 0.26 pp / day, continuing at this pace would see storages reach 80% by 1 November (the EU agreed target).

Last week, the EU Commission published a plan outlining how to address the Iran energy crisis: ❓How to read the AccelerateEU plan? @bruegel.org First Glance with @tagliapietra.bsky.social 🔗 www.bruegel.org/first-glance... 1/4

☀️ Good news! Renewables keep pushing fossil fuels out of the EU electricity mix. In 2025, wind and solar power was 291 TWh higher than in 2021. The fossil fuel share went down by 257 TWh. You can explore the data in our Bruegel European Clean Tech Tracker: european-clean-tech-tracker.bruegel.org

Which economy is more productive - Germany or the US? It seems the answer would be clear, but it's not. The mood in Germany is so deeply negative, even aggressively pessimistic, that I thought we had fallen behind by a lot. But here are the facts - they surprised me as well:

1/ 🔌🚗 New data published today for 2025 shows strong growth for electric cars in Germany! Or does it? Here are the facts, based on the recently updated #OpenEnergyTracker: ▶️ Purely battery-electric vehicles accounted for 22.2% of all new passenger cars registered in December.

The European Commission proposes to take a more central role in planning new electricity grid infrastructure. This can make a lot of sense but as my colleague @aroth.bsky.social points out transparency is crucial. Continuing to use a private & closed-source model leaves the EC open to criticism

The EC’s long-awaited "Grids Package" is finally out. Moving toward a system-oriented approach for Europe's infrastructure is the right step, but it won't work in a black box. In my latest for @bruegel.org, I argue why transparency is important to making this effective.

We launched our @bruegel.org EU Renewables Value Tracker based on great work by @mariejuge.bsky.social & @aroth.bsky.social: www.bruegel.org/dataset/eu-renewables-value-track Five insights 🧵: 1) The value of additional solar plants in south-east Europe and particularly Italy is still very high.

NEW🚨The response to Draghi’s call for action on energy has thus so far been more incremental than disruptive. But potentially significant initiatives are on the way. These will represent Europe’s moment of truth for energy integration. www.bruegel.org/first-glance...

👇 New @eu-untangled.bsky.social episode out: We discuss the EU's *AI regulation* with @nicolasmoes.bsky.social (Executive Director, The Future Society).

🔋 How much long-duration storage do we need in Europe, and what is the impact of #Dunkelflaute events? 🧾Take a look at our pre-print arxiv.org/abs/2411.17683 (with @kittelmartin.bsky.social & @wpschill.bsky.social). 👇 Martin's thread below is a great summary!

What exactly led to the Spain-Portugal blackout is still unknown, but this pod provides a great explanation of the power grid dynamics that are involved in these kinds of events. #energysky You will come away smarter, & not b/c you will know "the answer" but b/c you will know the questions to ask👇

1/ 🎙️ Lust auf einen Energiewende-Podcast am Wochenende? Wir haben für euch einen Deep Dive zum #Emissionshandel mit einem Gast, der dazu wirklich was zu sagen hat: Dr. Michael Pahle vom @pik-potsdam.bsky.social ⏩ #fossilfrei Folge 31 ist da! @diw.de @ariadneprojekt.bsky.social

Bottomline: the US will either falter and reverse everything, with substantial losses, or continue current path with huge losses. Credibility of this administration internationally is low, but the damage is deeper and will outlast it. Institutions provided no checks and balances.

🚨 Achtung Studis im Berliner Raum: wer hat Lust, uns bei der Arbeit mit Energiewende-Daten zu unterstützen? Join the Team #OpenEnergyTracker! openenergytracker.org Ggf. auch Mitarbeit beim Podcast #fossilfrei möglich. Ich freue mich auf eure Bewerbungen

Energiespeicher werden immer wichtiger. Zu diesem Schluss kommt unsere Kollegin Anna Billerbeck im aktuellen Ariadne-Explainer zusammen mit @wpschill.bsky.social, Alexander Burkhardt, @lionhirth.bsky.social sky.social @aroth.bsky.social ky.social und Dana Kirchem vom @ariadneprojekt.bsky.social 👇

Die neuen Szenariorechnungen zur Klimaneutralität 2045 aus dem @ariadneprojekt.bsky.social sind da! 🔽 Wie schon in früheren Studien zeigt sich, dass erneuerbarer Strom der wichtigste Energieträger wird. Ein schneller Ausbau von Windkraft & PV und ihre Nutzung für Mobilität und Wärme sind essenziell.

american masculinity is so amazing. caring about clothes as a man apparently makes you "gay" but our position on geopolitics totally depends on whether you wear a suit

Absolutely. Also we should pour all our energy into getting the next steps right rather than relitigating why we have not taken them already. We can do that later.

1/🔋 Langfristspeicher werden oft als eine Art Endgegner für die Energiewende betrachtet. Daher sprechen wir ausführlich über sie in der gerade erschienenen Folge 29 des @diw.de Energiewendepodcasts #fossilfreic....

Interesting and fun article by @euractiv.com on the possible and likely coalition options in Germany: www.euractiv.com/section/poli...

After the news we got from the #MSC2025 last weekend, talks have again started about an EU army. 👇 With @eu-untangled.bsky.social (my side project), we recorded an episode with Ionela Ciolan on that topic. She explains, whether we need a common army and what the EU needs to do to defend itself.

Blue and gold sensation!

It's wild when you think about it. 🇺🇸Republicans pressured reluctant Western Europe to invite #Ukraine to join #NATO in 2008 (Bush). Many think that move provoked this war. Now it's 🇺🇸Republicans who will pressure Europe to drop the invitation, to end the war When will Europe decide its own future?

1/ Bevor bald eine neue Bundesregierung die Verantwortung für die #Energiewende übernimmt, ziehen wir Bilanz, wie es bei der Ampel gelaufen ist. Neuer @diw.de Wochenbericht mit @adelinegueret.bsky.social , @aroth.bsky.social & @fsschmidt.bsky.social 🧵🔽 https://doi.org/10.18723/diw_wb:2025-7-1

Es gibt ein plausibles Szenario, in dem es nach der Wahl weder für Schwarz-Rot noch für Schwarz-Grün reicht. Etwa wenn BSW und Linke in den Bundestag kommen, die Union noch etwas verliert und die AfD zulegt. Dann könnte es sehr kompliziert werden.

#CDU drops to 28% in latest poll. Greens surge to 15%.

29. Januar 2025 Der Tag beginnt im Bundestag damit, dass man der Shoah gedenkt und er endet damit, dass Nazis jubeln.

Interessante Anmerkungen 👇 Auch vor dem Hintergrund, dass man der CDU traditionell Machterhaltung als oberste Maxime unterstellt hat. Hat sich dort was zu Gunsten von Ideologie verschoben?
