#Fridaydeepdive 💻: This week PIK Director Ottmar Edenhofer was kindly invited to present a lecture at the Oxford Martin School on carbon dioxide removal as a 'third pillar' for climate action. Tune in to watch the lecture and QnA in full. www.youtube.com/live/c0omzp_...

After a few months/year and a half of quite difficult news for offshore from around Europe (Hornsea 4 cancelled, auctions without bids in Germany and Denmark, etc), this is fantastic news and shows the industry is still alive and kicking - despite rising costs!

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:

This chart documents one of humanity’s greatest achievements, in my view. We just lived through the fastest population growth in human history. It would have been impressive if food supplies had merely kept pace — but on every continent, they grew even faster than the population.

Fantastic thread!

We love to say "costs fall X% every time capacity doubles." This paper looks at 87 technologies and says: actually, no. Past learning rates are not reliable predictors of future learning.

"Spain’s rapid renewables build-out means its power prices were set by fossil generation just 19% of the time, down from 75% in 2019. As a result, wholesale electricity was almost a third cheaper than the EU average" Imagine having cheaper power Gift link: www.bloomberg.com/news/article...

my takeaway from climate week nyc is that "climate storytelling" is a little too much "we must reimagine our deepest souls in relationship to mother nature and the moral abyss of the polycrisis into which we must now stare" and not enough "ok but get a heat pump"

Not sure how many scientists here have tried Claude Code or similar command line coding assistants. I had a complicated family property tax problem that was best solved by a brute force Monte Carlo simulation approach, so I spent a few days coding up and analyzing a model with Claude Code.

Hinkley Point C now over £45bn. Sizewell C - which was supposed to be much cheaper based on the experiences of HP-C - now at £38bn... Maybe, and hear me out here, new-built nuclear power is a tiny bit more expensive than renewables... 👀 Who could have known?

About 1500 of the approx. 2300 people that will have lost their lives across 12 European cities last week would still live, if it wasn't for our burning of oil, coal and gas. If we care about the right to life, we need to stop burning fossil fuels. www.imperial.ac.uk/grantham/pub...

NEW: Cheaper batteries mean near-24/365 solar is now economic☀️ We analysed 18 years of hourly insolation data at 12 places, to see how close to 24/365 electricity it was possible to get. The sunniest places get over 90% - and up to 99% - of the way... from just $100/MWh. 🧵

A HISTORIC MILESTONE: For the first time, solar power generated more electricity globally than nuclear, making it the world’s 4th largest power source. In just 5 years, solar output nearly tripled—from 79 TWh (Apr 2020) to 233 TWh (Apr 2025). The energy transition is speeding up. @ember-energy.org

The German Car Industry released its 10 prios for climate neutral transport (i.e. EU 2035 ICE-ban). Demanding lots of flexibility on target timing, PHEV, LDV & biofuels but stop short of asking for the ban to be scrapped entirely. And this last one made me giggle... www.vda.de/en/press/pre...

I will forever be haunted by this footage. Trawling has only been filmed underwater a few times in documentary history, and never with such clarity. What’s so heart-rending about these shots is watching how the animals don’t just get swept up — they swim for their lives. 🌎🦑🧪

The 1st future contract for #EUETS2 was released today. This is the first indication of what the eventual price might be: 73,57€/t Far too early to judge this development, but a first signal. Academic exp. much higher than that. EC assuming 30-50€, price mech. in the regulation 45€ (~60€ indexed)
