Here's fig 5, showing the estimated costs for a 100% hourly matched carbon free portfolio for Germany and Poland respectively.

The Y-axis on chart doesn't even go beyond 130 EUR, and the cost increase is pretty gradual.

(there's much more to the topic, obvs, but for today, this made my day)

Which report is this from? The Ember electrotechnical one?

I was wondering about something similar when reading the IEA decline rates report over the weekend. If investment trails off in the US the speed at which production falls is eye opening.

So in the UK, there's a new report from the NESO - their national grid operator. Looks like they expect a ~3x growth in data centre demand by 2030 (!).
July 30, 2025 at 3:01 PM
Holy balls. The NESO appears to be expecting something like a *tripling* of demand from DCs by 2030 based on their 10 year forecast - an extra 15 TWh / yr!

@nworbmot.bsky.social @iriepin.bsky.social how much "firm" power you reckon that might require? UK has a lot of gas to replace by 2030.

This post raised a full-on belly laugh for me at the end, but it speaks to a serious issue - I'm amazed by the lengths poor Dave Barry has had to go to, to convince Google to stop telling everyone he's dead in AI Overview answers.

There has GOT to be a word in German for when:

1. you lose your phone
2. person who nabbed it tries to cross the country with it on a train
3. realises it 's locked
4. gives up and hands it to the next person they see
5. who then calls the number on it to arrange to send it back to you

Have you found any really good framings of this?

The best I've found so far is from Hannah Daly, showing something you might describe as "the opportunity cost" of using clean energy for that purpose vs alternatives:

Hi David!

I think 1) might have already happened.

This was announced a little over a week ago, by Crusoe Energy and Redwood, with their new AI datacentres mixing solar panels and repurposed EV batteries. No figures on total MW capacity in the press release tho.

Is there a commonly accepted (and hopefully entertaining) name for these panels that go over where the air intakes of internal combustion engines in cars used to be for transitional designs like this BMW?

Whenever I see them on EVs I always think “nostril plugs”, but there must be a better term.

TIL: if you have a framework laptop, there is now a RISC-V motherboard you can buy, from a different company, that works with Ubuntu and Fedora already. This is a framework laptop with RISC-V running inside it.

Cory Doctorow has a similar concept which he calls "the shitty technology adoption curve".

It's a useful concept, and "above / below the API" is a nice SFW term, but it would be good to have one that is better for convos with ppl whose entry point to tech is "AI"

I have one query though. The figure you’ve used for deals like the nuclear power between Microsoft & Constellation for power at 110-115 USD / MWh.

Would that likely include any subsidies for extending life of clean generation in the IRA? The subsidies seem v generous for new builds.

Not just the shareholders, guidance from the board too.

The recorded video argument addresses every single point from the board:

I've attached the screenshots from the argument used. They didn't seem very convincing.

Wow, I hadn't realised that the Healthcare CEO guy who got shot also ran the same firm that was being sued in a class action lawsuit, about their automated decision-making system denying ppl care.

Snippet from the paper in the post from Meredith Whittaker below:

Y'know that #solarpunk trope of floating wind turbines in the sky, tethered to the ground, and feeding power down to denizens below?

This is one in China, serving 50KW at 500m, which is power for between 40 to 140 households.

Thank you for saying this. This is what opened @leahstokes.bsky.social really wonky but wonderful book, Short Circuiting Policy, and the simplicity of the message has always stayed with me.

At #greenio conf, seeing a talk by Juliette Frope, the AI project lead at the French govt. dept of climate transition.

The digital sector in France is the only sector *growing* in emissions where other sectors are either at a plateau, or falling slowly.

I'll link to this deck when it's available.

I'm at #greenio, and I just saw a presentation from staff at Backmarket about why they left AWS, and they specifically cited climate commitments and issues with transparency as the drivers.

At 700+ employees, this is the biggest firm I've seen say this so far.

If you gave seen larger ones, LMK?

TIL: the Fish shell is now mostly written in Rust!*

github.com/fish-shell/f...

Would this make it the only "major" shell written in Rust now?

* If you're using fish right now, your one is probably using still using C++. The next upcoming release has the new Rust bits.

Follow-on qn time...

Hey Dan, Alex (and friends)!

Sorry for the slow response.

I have a few things that might be relevant. I did a talk about something called the "Ten Tonne Rule" back in 2019. I've attached the three screenshots of the key ideas, plus the link to the slide deck.

Hi Michelle! If you aren’t following @chrisnelder.bsky.social’s stellar Transition show podcast, then there’s a good section covering a recent case with AWS’s recent nuclear deal in the most recent episode:

Should we do it like Germany? This was an email from last week from my provider, who is probably one of the best ones.

The rocket emoji always cracks me up when I see it.

Here’s what came up on my phone. It was a nice surprise, I don’t know what the cutoff point is though, so who knows maybe you get to humblebrag too?

If you’re waiting for a Certified Bluesky Elder badge thingo, then today I learn that if you joined in August 2023 you should likely have it. The notification just pops up out of the blue - no way I see if triggering it yourself.

If your first post is in Sept 2023 I guess you’re fair too, right?
