Abu Dhabi emissions to fall *50% by 2025* as a result of Barakah plants reaching full capacity, new large-scale solar projects, and increasing water desalination efficiency. Is this a new record for decarbonisation speed? #nuclear #ClimateAction arabnews.com/node/2007731/b…

@PhilbyB @22thinkinggirl The market design for private capital is leading us up the garden path wattclarity.com.au/articles/2026/…

@22thinkinggirl @MarkDuffett There's a big difference between public and private capital

Remember the $600 BILLION NUCLEAR LIE started by the Smart Energy Council (peak body for the renewables industry), used as electoral deceit by Labor and believed by many gullible voters? Well the blow out in the cost of renewables is making even that grossly inflated figure for nuclear look like a bargain. We are looking at costs blowing out to ONE TRILLION. YOU FOOLS FELL FOR LABOR’S CON JOB #Nuclear #Renewables

‘Running on Empty’ … a reminder of the implications of Shallow Storage wattclarity.com.au/articles/2026/…

"Pumped hydro highlights the issue. It provides long duration storage, synchronous system services and asset lives measured in decades, but much of its value is not captured in project revenues." 🤔 What other low-emission generators might be favoured by the called-for "market design changes that deliver long dated revenue support aligned with asset lives"?

Still very comfortable in my years-held position that round the corner kicks from set shots are a worse option than drop punts for any less than 75 degree angles #McStay #aflPiesDockers #footy

Need a roof.

“A gallon of jet fuel contains 34 kilowatt-hours of energy in a package weighing six pounds. A lithium-ion battery storing the same energy weighs 250 pounds. That density gap is why every military on earth runs on liquid hydrocarbons, why every container ship crossing the Pacific burns bunker fuel, why every combine harvester in Iowa runs on diesel, and why every 747 landing at Heathrow runs on kerosene. The fact that nobody wages war over solar panels is evidence of their limitations not superiority.” —@Shellenberger open.substack.com/pub/public/p/2…

‘Australia has one of the largest structural exposures’ to closure of the Strait of Hormuz #energy

Here at #CERAWeek this week I’ve heard @ErnestMoniz say several times that “solar energy doesn’t go through the Strait of Hormuz” Actually it does ⬇️

Hey @cleannrgcouncil, you need to align with larger organisations and start including nuclear energy as Clean.

@spenderallegra "crude oil reserves will last around seven years...For those people saying that the answer is, 'Drill, baby, drill,' just be aware that it's seven years of resilience" Such a ridiculous remark that you made in parliament. Drilling identifies *new* reserves.

Morocco didn’t suddenly “turn green” - it just rained again. After years of drought, a single wet season can dramatically reshape the landscape, especially around mountain ranges that capture moisture. It’s a reminder that climate is variable, snapshots can mislead, and two images don’t make a trend. Source: reddit.com/r/geography/co…

Like an appreciation of progress, reading and literacy are among the things that are good but cognitively unnatural. That is, they go against our evolved nature. We didn’t evolve with print; it was a recent invention. Reading, for many of us, has become so second nature that we just assume it’s the most natural way of getting information. But what we’ve seen, especially in the last 10 years, when video has become so cheap because of the cloud computing revolution and the broadband revolution, is that a lot of people, unlike us, much prefer to listen and watch than to read. You just see this: when I go to Google and ask a basic question about how to unstick my printer or solve a problem, I get like five videos. And I just want a paragraph that would solve it. I don’t want to see Seth saying, “Hi, welcome to my show. If you like it, subscribe and give it a like.” So just help me solve the problem. But clearly there’s something unusual about me, because people are going for the video. And the massive availability of video—of TikTok, of YouTube—means that people may not be getting the practice or putting in the effort into literacy, which we have reason to believe was one of the drivers of the Flynn effect and of cognitive sophistication in general. @HumanProgress

Earth's deserts are shrinking. 'Global desert area declined from 1985 to 2024 at a rate of 22700 km² (=1/3 of Tasmania) per year, largely driven by reductions in Australia, East Asia, Central Asia, and South Africa' agupubs.onlinelibrary.wiley.com/doi/10.1029/20…

Can’t wait for another AFL House announcement about an incorrect umpiring decision against the crows. Cue up another couple of Friday night games for us next year friends #aflcatscrows

If only anyone had warned them about this at the time.

"increasing penetration of variable renewable and distributed generation, further market integration, broader electrification, and evolving environmental and geopolitical risks place the European electricity system under increasingly challenging operational conditions, requiring higher levels of resilience"
