When it comes to the energy transition I'm a glass half full person.

I know: plenty of people would say that's terribly naive. They point to the scale of the challenge. They point to vested interests. They point to hard-to-abate sectors.

And they're not wrong. But here's what they miss.

In ihrem aktuellen FAZ-Gastbeitrag beklagt Katherina Reiche eine "Selbsttäuschunug" in der Energiepolitik. Tatsächlich fällt der Täuschungsvorwurf aber teilweise auf sie selbst zurück, denn der Text enthält diverse falsche oder irreführende Zahlen. Ein Thread. (1/17) www.faz.net/aktuell/wirt...

Passt aber auch in ein klimapolitisch katastrophales Bild. Es geht nicht um PV, sondern um das große Ganze. Mit fossilgas heizen? Hauptsache Freiheit! Gas fördern?Definitiv! E-Autos? Ja gerne ein paar, aber vor allem hoch-effiziente verbrennen. Das Muster ist für mich recht klar.

Ja, det är ju det. Ett elände , men vad tror man att man ska få med såna sorkar i ansvarställning? Man undrar om de främst inte begriper eller främst inte vill. Snart är det val igen!

Om ett "elektrifieringsmål" införs istället, och det målet är 100% till 2035 eller tidigare är det nog OK. Något säger mig att det inte är exakt det som föresvävar regeringen, men ändå.

This is probably one of the best energy system visualisations I've ever seen, and the interactive version (presumably by the same authors) is even better. 10 out of 10 points.

But then I got sidetracked by the fight against the existential threat the EU poses to the Western world.

UN environment report 'hijacked' over fossil fuels - top scientist The US and other governments derailed an agreement on a global environment study, its co-chair says.

I hope no one thought that politics stayed out of these reports (including IPCC). If so, you would be wrong.

Tired but still happy on the last day of the IPCC Lead Author meeting. Oh boy, this was intense but fun! Looking forward to the meet years @ipcc.bsky.social

I wonder how that went… ah well.

Merci!

Varifrån har du dessa data? Mycket användbart!

7/ Our key policy messages:
1️⃣ Variable renewables are the backbone
2️⃣ Electrification requires technology clarity, not technology neutrality

The car crisis tops today’s EU summit but leaders keep staring at the wrong problem

The issue isn’t the 2035 engine ban - it’s demand falling off a cliff today

With @sandertordoir.bsky.social and @lucasguttenberg.bsky.social, we show why flipping regs won’t help - and what the EU can do instead.

Europa wählt Importunabhängigkeit und Solarenergie

Wie können die Wünsche der Bevölkerung in Planung von #Energiesystemen einbezogen werden? Dem widmete sich ein Team v. ETH Zürich, FAU & @rifs-potsdam.bsky.social Es hat einen Ansatz entwickelt, der nicht nur technische und wirtschaftliche Aspekte einbezieht: www.rifs-potsdam.de/de/news/euro...

Cover of our report: First build, then break.

The energy transition can seem like a daunting challenge: how can we transform the polluting machines in so many parts of our economy in such short order?
 
Today we’re launching our report "First build, then break: a policy framework for accelerating zero-carbon transitions".

Now that the European Parliament wants to ban tofu sausage - what will happen to salami prezels? If sausage must be made of meat, do prezels now also have to be made of meat?

Influence of individual models and studies on quantitative mitigation findings in the IPCC Sixth Assessment Report - Nature Communications The paper analyses the impact of the uneven representation of models and studies on key mitigation findings in the IPCC Sixth Assessment Report. It finds that the model with the most scenarios has a considerable influence on several findings.

New paper with @glenpeters.bsky.social in Nature Communications today. We show how models and studies with a lot of scenarios in the IPCC scenarios database have a large impact on key findings, including emissions reductions, net-zero GHG year, and coal, gas, and oil consistent with 1.5°C.

The oldest trick in the climate delay playbook:

1. Rule out all other measures as unnecessary and counterproductive because we will introduce CO2 pricing

2. Then rule out CO2 pricing because it would make things unaffordable

3. Checkmate

Article abstract

Excited to share my new article on EU energy solidarity published in the @jei-publication.bsky.social. You can find the article here: www.tandfonline.com/doi/full/10....

Viele nationale CO2-Steuern sind zu niedrig, um Emissionen wirksam zu senken, und dienen primär symbolischen und fiskalischen Zielen. Das zeigt eine aktuelle Studie der FAU Erlangen-Nürnberg, der Universität Potsdam und des RIFS Potsdam.

Europe’s Car Industry in Transition: Stuck in Neutral or Shifting into Gear? Europe’s automotive industry is entering a decisive decade but lacks a clear map for navigating it. While global competitors accelerate their shift toward electric vehicles, Europe’s strategic focus r...

Europe’s car industry may have just dodged a +25% US tariff – but this is no reason to relax. Deep structural challenges remain, and the EU lacks a common diagnosis for fixing them.

My new policy paper argues that a coherent EU strategy needs to rest on three uncomfortable truths: 🧵

This year's @irena-official.bsky.social cost report is missing my favourite figure on LCOE, so I replicated it with their data + Lazard for NGCC 👇

Please @irena-official.bsky.social add it again next year!

This graph also very nicely shows how solar and wind power complement each other across seasons. The two together are pretty constant on this timescale.

yes, you're absolutely right. Without knowing the numbers, I would even guess that this was the single most important emissions reducing investment, at least in some countries like US and UK, although it mainly happened for reasons other than protecting the climate

no, because I don't know what "breakthrough tech" is, and I doubt that it is needed. I would agree to the statement that if emission reductions come from measures that, even if scaled up, cannot eliminate emissions, they are probably not steps towards and certainly not necessary for zero emissions

Thanks - interesting paper! If I read it correctly, the ETS price as such doesn't exactly affect investment expectations, but a high floor price, above the highest expected ETS price, does. What does that mean - that certainty is key for investment, or that certainty AND much higher price needed?
