A while ago I made this chart to illustrate that yearly additions of solar and wind (in TWh of energy) are growing fast while nuclear is largely stable. But solar and wind started small versus the older and established technology nuclear. This year we've reached a new milestone.

The cryosphere is in real trouble. That means that people and agriculture downstream will be too.

So che può sembrare folle, ma ancora non siamo al picco di questa ennesima ondata di calore. Oggi, lunedì, si sono registrate diffusamente temperature prossime o localmente superiori ai 40 °C, in particolare in Sardegna e sulle regioni centrali, in Emilia Romagna e sul Triveneto. 1/7

NEW BLOG FOR YOU Google's energy consumption numbers in their new climate report are mind-blowing. 2 years ago they flipped from linear to exponential growth, and their climate impact is blowing out, too. A WILD testament to the obscene bloat and waste of GenAI: ketanjoshi.co/2026/07/01/g...

What if... we made things less crap? No war, no billionaires, an end to poverty, gender equality, equal access to health & education, and a liveable planet. Um, yes?? A new report shows us how this seemingly lofty goal can be achieved... and all it takes is to tax the rich. youtu.be/5tsqotjWSy8

Interesting: the spatial pattern of afforestation matters for climate. It’s well known that reducing forest edges affects biodiversity and produces a climatic buffering effect, but (in China) it also produces more biomass (carbon) than planted forests with more edges.

RECORD YEAR: 2025 was the biggest year ever for renewables. A record 692 GW was added, mostly solar. More importantly, non-fossil sources generated 43% of the world's electricity and fossil generation fell. More in Bright Spots: open.substack.com/pub/janrosen...

Europe urgently needs more (and more democraticly distributed) AC but AC is not a bolt-on fix. The divide between the Cooled and the Damned will persist and even grow. And nobody’s going to AC the farms, forests, the ocean.

NEW The UK will adopt one of the world’s most ambitious climate targets as Labour takes on Reform opposition to net zero and moves to neuter the Green Party’s rise. Ministers have accepted @thecccuk.bsky.social's recommendation for an 87% cut in emissions by 2040 👇 www.thetimes.com/uk/environme...

NEW RESEARCH: We modelled three Hormuz closure scenarios. Europe never physically runs out of gas in any of them. But under the worst shock, LNG hits $54.9/MMBtu, above the 2022 peak. Energy security in 2026 isn't empty pipelines. It's empty wallets. Full paper here www.cell.com/one-earth/fu...

Solar plus storage in India is cheaper than building fossil fuel power plants. So they build the solar.

The big question - when indeed will the Environment Agency do what it exists to do and, you know, er, enforce the law? Great work by @nicolacutcher.bsky.social and @friendsriverwye.bsky.social

This morning Irish climate experts wrote to Minister O'Brien @deptcee.bsky.social to express deep concern that urgent #methane reduction risks being undermined if climate targets are set using a ‘temperature neutrality’ approach. 1/13

If you're reading this, my cat and I have boarded a one-way flight out of the United States. The Trump administration wrongfully denied my work permit renewal; after months of demanding that they follow the law, we have run out of legal recourse, and I have no choice but to leave the country. (🧵)

Pakistan: solar just overtook coal as the largest single source of electricity. 21% of power from solar in 2025. Up from 2% in 2019. Coal peaked at 20% in 2020. Want to read more about one of the fastest solar transitions anywhere in the world? Sign up to my Substack janrosenow.substack.com

btw, regulators confirmed to us this morning that the 19 new turbines (and the 27 already on site) are not part of an air permit granted in March, meaning xAI has more than 1 GW of unpermitted gas power at Colossus 2 right now

Interesting new paper documents clearly how the IAEA has been overestimating the growth of nuclear time and time again. It's the inverse of what I've documented for solar and batteries. doi.org/10.1016/j.er...

🟡 Naru Research is open for business 🟡 So in some very cool news, my new consultancy is now officially at a stage where I can declare it open for business! 🎉 If you're keen on doing good in the climate and energy transition, but need research and strategy insights to help drive impact, let's chat!

The next week is looking like it might be toasty for global temperatures in the latest model runs. If this holds it would put us well into record territory for this time of year: http://www.karstenha...

Solar plus storage: $54 Coal: $70-85 Gas (methane): $100 The math gets pretty simple.

Remember that company that Trump paid a billion dollars so that they *wouldn't* build offshore wind farms in the US? They're doing amazing shit over in Europe. Floating turbines are so cool!

I don't know how to call the point in the transition where ecargo bike is featured on the Price is Right but we are there.

39 countries cut energy taxes after the Iran war. Politically popular but self-defeating: untargeted subsidies blunt the price signals, lead to higher demand, cost the tax payer significantly more and provide less incentive to invest in alternatives.

Earlier this year, Trump released a bizarre executive order touting the controversial herbicide glyphosate (a.k.a. Roundup). Why? Our new investigation shines light on that—and a whole lot more.

Quoted in @ketanjoshi.co's piece in @theguardian.com: a year ago Spain's grid collapsed. Solar was blamed, return to fossil predicted. Investigations found voltage failures. Then Hormuz closed. Spain was shielded as renewables cut wholesale prices by 40%. www.theguardian.com/world/2026/a...

Potentially hyper-cheap sodium batteries are becoming commercially available and are getting LFP battery specs. This is nuts! This could lead to *incredibly* cheap batteries! electrek.co/2026/04/27/c...

Now is the time for bold fiscal, industrial, and policy action. Those who seize this moment will define the future, those who refuse it either due to pressure from deficit hawks and anti-tax advocates or thanks to the power of oil right now will be left in the past. 23/end

So while oil and gas stand to gain a lot of money from the present boom, they will be operating in an environment where oil and gas are increasingly uncertain, risky investments, renewables remain reliable, cheaper, and more popular than ever, and capital for carbon is even scarcer. 18/x

It's time to talk about that thing I spent most of my PhD studying: OPEC! This is going to be a bit of a messy situation though I think, overall, this is a positive development for energy transition so here goes my take on what to expect. 1/x #EconSky #EnergySky #ClimateSky #Greensky
