I'm delighted with my heat pump.

But my experience getting it installed taught me what’s been stopping many more people from getting one (so far).

I wrote for @politicshome.bsky.social on the hurdles that government needs to think about as it implements the Warm Homes Plan. πŸ‘‡

NEW ANALYSIS: UK emissions fell 2.4% in 2025 as coal fell to a 400-year low. Incredibly, we used less coal last year than than in 1600, when Queen Elizabeth I was on the throne and Shakespeare was writing Hamlet.

All the details in our article: www.carbonbrief.org/...

Paramount-Warner Would Create a Hollywood Jobs Apocalypse - The American Prospect The deal comes complete with so much debt that it would almost certainly lead to mass job loss. That could prove to be an argument against the deal in court, too.

The great British electricity puzzle It turns out that making the transition to clean energy while keeping the price down is hard

This is a frustrating column by Martin Wolf - which is sadly typical of a lot of economics commentary on GB energy.

It does identify some of the key causes of high electricity prices - including Britain’s high exposure to gas prices and rising network costs. But there’s a lot it leaves out…

This thread has the most succinct and convincing analysis of the by-election result that I've seen so far today.

I could have understood it as house style for acronyms, but the IEA, PPP and IMF say otherwise.

I guess this is just one of those mysteries

I'm revisiting Stonehaven's paper on the future of the UK gas fleet, and it's as good and interesting as when I first read it. But what on earth is going on with these country names? I'm perplexed.

I'm guessing this is a user who isn't classified as an EII? Because they should be exempt from RO and FiT (right?)

The complaint about being excluded from the NCC scheme also rings a bit hollow, since that just shifts costs onto households.

Multiple people tell me the only reason they still use Facebook is for FB Groups. So, of course, Meta is doing its best to ruin that feature with an unstoppable AI inviting hundreds of people to someone's private tea party group.

So the new cabinet secretary will indeed be Antonia Romeo

Here’s what we think she needs to prioritise

Happy Centrica results day. Some years ago I would have been appearing on BBC Radio, usually alongside Martin Lewis to explain (note: not defend) why it made a profit (work of the devil etc).

So let's have a little look at a couple of interesting things going on in the results...

Air-to-air heat pumps: a low-carbon solution for UK homes A2A heat pumps can provide homeowners with an additional option for decarbonising home heating

February is a great time to talk about… air conditioning. Otherwise known as air to air heat pumps, which can heat as well as cool your home, very efficiently.

We have a big new report out today on how suitable air to air heat pumps are for British homes. The answer: quite a lot!

Dan wasn't even born before decimalisation (nor was he anywhere near the UK when he was born) but still he yearns for Britain's pre-decimal times 55 years later.

Of course. Why would you invest in soft power?

It just helps in the kind of warfare that:

a) Russia has shown it's actually good at;
b) Russia is waging on the West already;
c) The UK/NATO nuclear deterrent is useless in preventing;
d) Costs a fraction to fund compared to military hardware.

The @qmul.bsky.social news article on it is pretty shoddy too. This line which subtly conflates the annual cost of curtailment in 2025 to the total projected cost between 2025-2030 makes it look like we'll be spending Β£20bn per year. I had to read it twice to be sure. A poor effort there.

I have today been informed that, despite personal assurances to the contrary, the Green party have once again used my image and misrepresented my words on a second leaflet circulated in Gorton and Denton ahead of the by-election. I have now lodged an official complaint with the returning officer.
