We don't need to speed up production. We need to slow down. We don't need to write code faster. We need to think through what we write. We've spent decades working to ship faster, and that's landed us in a world of hurt. Build better products, not faster.

Data center survey reveals majority believe renewables and BESS are the ideal energy mix, power issues start in 2027
54% of respondents cited “energy availability and redundancy” as the single greatest obstacle to successful data center development between now and 2030.

I keep reading that AI has driven huge DC growth; which is driving gas resurgence. I’d expect to see an inflection point in the growth; either now-ish or in the near forecast. And I don’t see that in either total power or in gas. CA is the wrong state to see that? What’s happening.

I was listening to @trientertainment.bsky.social … and then “something unexpected happened” when Marina Hyde revealed a new Adam Curtis film called Shifty due out in June! Podcast went out 6 days ago but I can’t find any more about it. I did learn that there is a DJ called Adam Shifty tho.
Transcript of the show:

“I watched a new cut of Adam Curtis's forthcoming series of films, which I don't think people actually know is forthcoming, but it is. It's coming to iPlayer in early June, I think, and it's called Shifty and it's about the 80s. It's a sort of social history, so it's totally different from what we did before.

It's really interesting. Kind of like how we all shifted in a sort of consciousness, shifted to this completely individualistic thing. He's very good at making you realize how things felt when they were happening and your memories are false.”

I thought it was remarkably fast! 👏 Getting the cities (mostly) back online before night fall was a huge win in so many ways. When/if we learn more about the causes it’ll become clear how it came back online. But it’s my understanding that there was black start required.

Rapid (your views may vary) recovery of the Spanish grid. For those on #energysky who are following our news. 10hr after the blackout. At 70% of predicted load. Detail in the alt text. Long way to go to meet tomorrow’s peak. Src: (in Spanish and behind paywall) elpais.com/espana/2025-...
12:35 and the grid demand collapses (blackout) to 10GW

Fails to meet the usual demand peak of 34GW at 21:00

Currently back at 19GW of expected 27GW at 22:35 (70%)

You mean “Inertia” within the context of spinning turbines? Very much looking forward to a long read about multiple cascading system failures. 😀 And, yes, as uncool as it is to say so - it’s been a good recovery job so far. Compare to Heathrow being offline for almost a full day.

Tom Harvey @tom.electron-one.com · 28/04/2025
Fully agree but “what should happen” and “makes more sense” aren’t such clear concepts to ERCOT 😀 But more seriously, there are still supply chain, planning and grid capacity issues with dropping gas turbine generators near your DC

I would be remiss not to live post from #spain to #energysky today; here’s the grid mix now (massive blackout across the country) vs yesterday. Courtesy of @electricitymaps.com Looks like the gas and nuclear have *vanished*. But solar is ~half of what is was yesterday. And it’s plenty ☀️ today
Yesterday’s grid mix in spain. Predominantly solar (12GW) with a bit (4GW) of each of hydro, wind and nuclear. Today’s grid mix, with only solar and wind generating any meaningful amount. But still way less than yesterday. Solar is down to 5GW and wind is only 2.75GW. And that’s all the whole country gets today. Blackout time.

Tom Harvey @tom.electron-one.com · 28/04/2025
Sure, but then those industrial processes need to happen where there is generation and grid capacity. When there isn’t enough grid capacity, and we want to smelt, this is one way to transport the power to the process.
010
Tom Harvey @tom.electron-one.com · 28/04/2025
And, yes, as a stop gap. Capacity can be added but the wait time for that work to be completed often runs into a decades long time scale. So it’s a stop gap that has legs to be a legitimate business and a solution that allows progress in the meantime

Tom Harvey @tom.electron-one.com · 28/04/2025
I think I wrongly implied “no power grids”. If I was being clearer, it would be “not enough power grid capacity”. A big problem in a lot of parts of the grid in many countries. The DSL/Fibre analogy is a great one.
