@zamafir.bsky.social Any idea how to verify my (potential) 2026 Ioniq 9 uses CATL batteries? Can I verify something in the VIN or something?

Can confirm this is an excellent post all the way to the end. I like that he starts with the maintainability and convenience benefits.
Fantastic one year EV9 review. Cannot echo this enough:

“If you're really trying to optimize, topping off to 80% from a high-power charger is the same amount of time you'd take for a rest stop anyway.”
I blogged about our ~1 year experience of owning an EV

There is nothing inherently wrong with the Earth 400k years ago. The problem is that humans evolved to live in the climate we have today, and we built our infrastructure for today's climate. The same goes for the animals and plants that we love and love to eat. Climate change is pain for everyone.
The last time Greenland was green was 400,000 years ago, when sea level was between 6 and 12 meters higher than now.

Today, atmospheric CO2 is 1.5 times greater than it was back then.

Goodbye to most of the world's coastal cities, I guess.
we consider ourselves to be worlds apart from American Republicans but the Norwegian media habit of celebrating the impacts of fossil fuel use as beneficial to our lives is indistinguishable from the fascist accelerationist position over there

Country 9 in global oil reserves has invaded country 1 and arrested its president. Country 7 is under sanctions and its refineries are being destroyed. Country 2 is facing off with country 6. And there are riots in country 3. But oil is only $60/bbl. Maybe oil is not as critical as it used to be?

Allow me to connect some dots for you:

Too much of the world currently relies for its basic functions on resources which must be continuously extracted. You burn that oil one time and oops, now you need more.

Geopolitical horrors are, in fact, one of the reasons we need to move to renewables ASAP.

Outstanding piece from @billmckibben.bsky.social today that gives hope that we have the technology and the means to stop fighting over oil.

Thread: Each week I run a simulation of Australia’s main electricity grid using rescaled generation data to show that it can get very close to 100% renewable electricity with 24GW/120GWh of storage (5 hrs at av demand)
Results:
Last week: 100% RE
Last 227 weeks: 98.6% RE (1/5)

solar won't work here, it's only useful in really sunny areas of the world like Britain
A picture is worth 1000 words...

This appeared on the BBC News today, showing the increase in solar electric generation in the UK.

Not sure who produced it, but genuinely think this is a genius piece of scientific communication - the construct and choice of colour scale is near-perfect.

Chapeau!

A little perspective…
Our Solar System is orbiting the center of our Galaxy at about 220 km/s so in 2025 we collectively traveled something like 7 billion kilometers across the Milky Way. Once in a while, when you have a moment, it’s worthwhile to take a look around, see where you are, and appreciate how far you’ve come.

Days like today I’m thrilled to have a home battery system. If the grid fails I got plenty of juice for us and our neighbours. Going solar+battery has a ton of benefits that don’t fit neatly into a standard ROI calculation.

@zamafir.bsky.social Any idea why BMW iX3 is showing “estimated range of up to 650 km” on their Canadian site but keep quoting 800km/500mile on video reviews? Is this simply different estimate methodologies between countries or is NA getting a different design?

Interesting.

“Hydrogen “indirectly” heats the atmosphere through its interactions with [hydroxyl radicals] effectively ‘using up’ these detergents and leaving less to react with methane.”

Hydrogen emissions are ‘supercharging’ the warming impact of methane - Carbon Brief
The warming impact of hydrogen has been “overlooked” in projections of climate change, authors of the latest “global hydrogen budget” say.

Unbelievable. So much so I had to see if this was actually posted. It was, and amazingly it hasn’t been deleted. 😱 x.com/ustreasury/s...
it is a very strange moment when the US Treasury department is celebrating people demanding a higher return on investments in US debt.

Me: why am I being assigned so many 1600 elo opponents?
Also me: oh right, I lost over 200 elo while playing chess from the beach.

New Zealand just recorded its first-ever day of zero coal- or gas-fired electricity. In fact two days, 20 & 21 December. (Still some co-gen, about 1.8%.)

This Yglesias piece in the NYT is horrifically bad. Almost every "fact" it cites is provably false. At best it is cocktail party banter from a pundit who knows nothing of energy. At worst, it was cut/paste from oil industry talking points. So, a rebuttal: www.nytimes.com/2025/12/18/o...
