What mattered this week

"The biggest energy security threat in history" - is also the moment the world moves off fossils faster

Say what? The IEA's Fatih Birol is clear: It’s the biggest energy crisis. World has lost 13 million barrels of oil a day. In 1973, it was 5m.

So what happens? The world votes with its wallet.. Chinese battery/EVsolar exports up 70%  🤯. Nigeria’s solar imports up 4x. Germany added 1GW of batteries and EU announced a continent wide plan to reduce gas. And cars? India: EVs up 75%. Indonesia: +125%. Vietnam: 40% new cars EV.

Paid-£84-to-take-power on Tuesday. £169 cost on Thursday. When are you using electricity?

Paid to take power. Yes the GB system is now regularly paying to use electricity.

Why? Because we have too much. Lots of solar (record this week, 15GW) and wind (over 50% of power), not enough storage.

Reeves's move? The Chancellor said she's planning to break the link between electricity and gas prices. If it lands, a windy hour gets priced as wind.

Your move? If you buy power for industry, sign corporate PPAs, or size batteries — the structure is shifting. Cheap moments become the opportunity.

EVs will win: It’s chemistry, not thermodynamics. There. I said it.

Huh? You can only get so much from a tank of petrol. Ever.

OK? Batteries can get a lot better: CATL announced a 1,500km battery that charges in 6 minutes. 😱

And next? “The boundaries of electrochemistry are still far from being reached, and the possibilities of materials science are still far from being exhausted" - CATL’s founder

One thing to worry about

Japan had to create a new word for 40°C heat days.

Say it after me: 酷暑日

They didn’t need one before.

We're all going to need it now.

One thing to be optimistic about

For the first time, clean power met ALL new power demand over a whole year.

Fossils fell despite the global economy growing.

• Solar alone met 75% of new global demand

• Renewables (33.8%) beat coal (33.0%) for the first time in 100 years

• Total fossil generation is now in a permanent terminal plateau (@AssaadRazzouk)

If you’ve got more time…

It's been over a year since we looked at the the massive, terrifying disaster movie that is AMOC. 🙀🙀🙀

Carbon Brief dropped a big explainer. The Guardian followed up (and made it about nasty billionaires 🤷‍♂️)

• The mechanism: cold, salty water sinking near Greenland drives a planetary conveyor belt. Keeps Europe warm.

• The signal: peer-reviewed work now thinks this could break down mid-21st Century.

• The effect? NW Europe gets colder winters in a warmer world. Sahel monsoon fails. North Atlantic ecology rewrites

If it goes: we’re cooked.

Write docs 4x faster. Without hating every second.

Nobody became a developer to write documentation. But the docs still need to get written — PRDs, README updates, architecture decisions, onboarding guides.

Wispr Flow lets you talk through it instead. Speak naturally about what the code does, how it works, and why you built it that way. Flow formats everything into clean, professional text you can paste into Notion, Confluence, or GitHub.

Used by engineering teams at OpenAI, Vercel, and Clay. 89% of messages sent with zero edits. Works system-wide on Mac, Windows, and iPhone.
