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.

China’s clean-energy revolution will reshape markets and politics The world’s biggest manufacturer now has an interest in the world decarbonising

“China is now making more money from exporting green technology than America makes from exporting fossil fuels. This trend will continue simply because renewables are cheap.” 🔌💡

Spain’s Renewable-Energy Boom Loosens Gas’s Grip on Power Prices Soaring renewables output in Spain is weakening gas’s grip on electricity prices, setting the country apart from much of Europe where fossil fuels still dictate the cost of power.

"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

Shifty - A new series by Adam Curtis coming to BBC iPlayer in June 2025 Shifty shows, in a new and imaginative way, how over the past 40 years in Britain extreme money and hyper-individualism came together in an unspoken alliance

Ooh, Adam Curtis is back.

"...life in Britain today has become strange - a hazy dream-like flux in which no one can predict what is coming next. While distrust in politicians keeps growing. And the political class seem to have lost control."

PyPSA; there goes my weekend! I’ve been looking for an excuse to dig into that.

Spanish Prime Minister Pedro Sanchez announced that his country will submit a draft resolution to the UN General Assembly calling for "urgent action to stop the massacre of civilians in Gaza and ensure the entry of humanitarian aid into the Strip."

Can’t think of a topic less parochial than global climate. Thanks for calling it out; he has given a lot of his wealth to his PR team.

Swoon! What a great project! Don’t suppose you’ve open sourced the code?

Much ado about the role of renewable energy (RE) in the Spanish blackout. The investigation into the effective cause is still ongoing, but many pointed to the fact that RE has no ‘inertia’. Is that true? The answer is: yes, but ... 🧵

Replies to criticisms of my posts on ChatGPT & the environment And a little manifesto of how I think about climate change

“Everything is additive” - What did you take from the comments against “every Wh counts” in here andymasley.substack.com/p/replies-to...

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.

Can you link the source of this? Would love to see more of the context.

What's the carbon footprint of using ChatGPT? Very small compared to most of the other stuff you do.

Turns out individual actions aren’t the real problem; systemic change is needed to solve climate change … again.

But make it “AI”

Some great⚡️analysis here from @hannahritchie.bsky.social which I’ve massively oversimplified for an intro.

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.” From The Rest Is Entertainment: How Liz Hurley Slid Into Billy Ray Cyrus’s DMs, 29 Apr 2025 https://podcasts.apple.com/gb/podcast/the-rest-is-entertainment/id1718287198?i=1000705296835&r=113 This material may be protected by copyright.

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.

I enjoyed this summary from @lionhirth.bsky.social on the inertia topic. www.linkedin.com/posts/lionhi...

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.

Main upside of the outage for me - excuse to get deeply nerdy!

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%)

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.

Probably shouldn’t have made snarky comments about the Texas grid this morning… Of all days… When I live in Spain. 🌚 #energysky

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.

Back online in my apartment on central València. Will likely take a while to get the whole country up but I’m surprised I got back online so fast after such a widespread outage.

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

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.

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

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.

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
