A great chart for showing the regional economic drivers for electrification of transport, heating and industry, and adoption of renewables.

High importers have the most to gain in near term economics.

However, the whole planet looses if we don't move as fast as we can in all regions.

Tony Blair pushing the agendas of oil and gas industry is probably all about the money he gets for it.

Purposefully undermining initiatives to address the climate crisis and lower long term bills, is certainly morally bankrupt.

Are we finally seeing the signal emerging from the noise w.r.t China de-carbonizing?

Other import signals support optimism that this is s real trend:

Electrification of transport is progressing rapidly.
Wind, Solar and Batteries are building out rapidly.

Both are progressing exponentially.

Another good practice is to put stuff you are directly quoting in "quotes" that way folks know where you are writing and what is being quoted.

The error in the article was reported by others and has since been fixed.

Good practice is to read stuff you copy and paste so you can catch errors like this before propagating them.

You got the figures correct, as per the article, but got the wording wrong on market share, while absolute sales did increase the market share dropped from 3.7 to 3.1%.

I'd be too busy ordering the curry wurst :-)

Few things smell as enticing as fresh chippy but aren't us Brits Europeans?

Illustration of the Dutch Reach. You should reach across with your non-door-side hand to open a car door, because it forces you to look behind you.

Last night, I got properly "doored" for the first time. A car in the road to my right paused, and the rear left passenger threw open his door without looking, right into my path. I ended up on the floor, badly winded but ok.

If you don't know what the "Dutch reach" is, NOW is the time to learn.

It’s not too late for states and Congress to stop Trump from subverting the midterms With only nine months before the midterm elections, Trump is plotting to prevent Democrats from taking control of Congress.

I am regularly asked what specifically blue states and Congress should do to protect the midterm elections.

Here you go, I list and explain them one by one.

"A modern-day concentration camp ... People have been killed by the staff here." Irish citizen Seamus Culleton has been in ICE detention since September, despite having a valid work permit and his own business in the US.

That was who I was thinking of, but it's time for @octopus.energy to call Dale Vince out directly for peddling lies.

Time to call out names. Members of the public might not realize who is peddling lies to push their own agenda.

It's Impracticality vs Inefficiency.

Neither hydrogen nor synfuel at scale are viable practically and economically.

Both have to compete against existing low cost kerosene to grow market share. To displace kerosene they have to be as practical AND be competitive on costs.

Both are niche at best.

Even liquid hydrogen has low volumetric energy density while means larger, heavier and higher drag fuselages. Less utility and higher energy demand.

Synthetic fuel retains the high volumetric energy density of current aviation fuel so can also be stored in the wings, keeping drag and loading low.

I inhaled traffic fumes to find out where air pollution goes in my body BBC health correspondent James Gallagher gets his blood analysed to understand how air pollution is killing us.

BBC article on testing how air pollution gets into the blood:

www.bbc.co.uk/news/article...

Just one tiny paragraph and what to do about...

"Changes to cars – not just sales of electric vehicles, but emissions standards on newer diesel and petrol engines – are improving air quality."

"We find that the principal drive for global warming acceleration began in about 2015, which implies that 2°C global warming is likely to be reached in the 2030s, not at midcentury" - James Hansen et al.

YouTube video by Democracy Docket DESPERATE Trump Plans Hostile Election Takeover

In this episode, I explain Trump’s escalating threats, DOJ ballot seizures, and the real plan to undermine free and fair voting in targeted states and cities.

Transportation: The First Sector to Flip - EV Curve Futurist EVs, trucks, and fleets are electrifying faster than expected. Used EVs, falling costs, and battery advances are collapsing ICE economics.

A few people asked for it, so I built it. Battery costs vs NEV sales. As battery pack costs fall toward ~$100/kWh & below, EV adoption doesn’t rise linearly — it inflects. Inflation & supply-chain shocks add noise, but manufacturing scale & chemistry dominate. Chart + data now live. #Bettrification

Jikes

The big winner for Jan 26 was PHEV that grew by 47.3% vs Jan 25, this brings them much closer to parity with HEVs.

BEVs remain 2nd largest segment behind Petrol which shrank 1.9%. Diesel shrank even more dropping 8.8%.

@smmt-ukauto.bsky.social's UK new car registration data for January 2026 show BEV sales grew by 0.1% but as the overall market grew by 3.4% so the share shrank a little to 20.6%.

This shows in the market share trends with BEV no longer ahead the later adopter curve they had been tracking.

The Power of the Sun While its implementation as a renewable energy may seem new, humans have used solar energy for hundreds of years.

“The scale of solar being deployed in such a short period of time has not been seen, I think, anywhere ever before.”

This is my take on solar adoption in Pakistan covered by National Geographic.

Khronos Group releases Gaussian Splatting release candidate for glTF

The Khronos Group announces a release candidate for the KHR_gaussian_splatting baseline extension. This extension enables storing 3D Gaussian splats in glTF 2.0, the most widely adopted 3D asset delivery format.

The new extension establishes an open foundation […]

They certainly can. Achieved a combined COP of 4.07 this week!

Over 5 times better efficiency than our old combi boiler and no noxious emissions to boot.

Hope this is interesting. I enjoyed pulling this one together.
