I don’t know, @AlexCrawfordSky, the sea of Hezbollah flags at the funeral seems like a massive clue. If only you were there to check.

@LoftusSteve @g_f_red That’s fine as long as there are plenty of public rentals. Which there were, until Mrs Thatcher‘s gigantic giveaway of public housing.

@g_f_red It must be nice living in an alternate reality. One where the Government are going to build 200k public housing a year. Tyrone is dealing with reality. Nobody is doing that again. Rent controls destroyed private rentals and will do so again, without anything to replace it.

We had rent controls in Britain until 1915 to 1988 and during this time housebuilding regularly hit over 300k per year. Since they were removed, the house price to income ratio has gone from 4:1 to around 8:1, and housebuilding numbers have collapsed.
Nick Tyrone@NicholasTyrone

Rent controls are a really terrible idea, they never work as intended and just cut supply of properties available. It’s like a lot of ideas on the left these days - it runs on vibes and nothing more.

@PhilipProudfoot @afneil @MichaelLCrick He could have added the word 'currently' and avoided any doubt and saved you from having an to explain what he meant even through he didn't say it. Are you always so forgiving about what politicians mean versus what they actually say?

Polanski is a know-nothing blowhard. The only Jewish person to lead a political party — bar, that is, Benjamin Disraeli, Ed Miliband, Michael Howard, Jimmy Goldsmith and Herbert Samuel. He is clearly ignorant of the country’s history. And much more besides.
Zack Polanski@ZackPolanski

For whoever needs to hear this I'm the only Jewish person to lead a political party - third largest in the country. The Daily Mail have been & always will be my enemy - they historically supported fascists & continue to do so. I'll take no lectures from them on Antisemitism.

@RichardMeyerDC There is a meaningful difference between "energy" and "dispatchable capacity." The renewable fans don't seem to understand that. It doesn't matter how much energy solar / wind has produced if you can't schedule it.

Richard Meyer@RichardMeyerDC·
The core analytical error in the "primary energy fallacy" argument, that renewables plus electrification will dramatically cut total energy needs, is that it treats energy as interchangeable. A TWh of gas isn't just energy. It's dispatchable, energy-dense, and seasonally storable. A TWh of solar is none of those things without substantial infrastructure to make it so. The leap from "EV motors are more efficient than combustion engines" to "the transition is easier than you think" skips over the hardest parts of the problem. Electrification can eliminate some conversion losses while introducing new ones, like curtailment, storage round-trip losses, overbuild, and grid expansion. If we look at how much infrastructure is needed to support an electric heat pump with renewables in the dead of winter, we'll see that gas delivers far more value than a Sankey diagram shows.

Die Energiewende wird leichter, als viele denken. Das liegt an einem weitverbreiteten Missverständnis, das Skeptiker ausnutzen, um Angst zu schüren. Denn: Nein, wir müssen das fossile System nicht 1:1 ersetzen. Wir brauchen nicht alle Primärenergie von heute. „Primärenergie“ ist die Energie, die den natürlichen Quellen entnommen wird. Ein Liter Heizöl enthält 10 Kilowattstunden (kWh), ein Kilogramm Steinkohle 8 kWh usw. Zurzeit verbraucht die Menschheit global 180.000 TWh Primärenergie. Erneuerbare stellen davon deutlich weniger als zehn Prozent. Um die fünf Prozent. Das ist ein Fakt, aber komplett irreführend. Denn Primärenergie ist ein bedeutungsloses Konzept in einer elektrifizierten Welt. Es sagt uns, wie viel Energie in Energiequellen steckt, bevor wir sie umwandeln. Aber nicht diese Energie ist für uns wichtig, sondern die erzeugte Energie. Wir müssen alle Energiequellen umwandeln, damit sie nützlich werden. Schließlich kippt niemand ein Fass Öl (159 Liter) in seinem Wohnzimmer aus und erwartet, dass es wärmer wird. Und bei der Umwandlung sind elektrische Systeme deutlich effizienter als fossile. Jede kWh Energie, die wir in ein elektrisches System stecken, kommt mit höherer Wahrscheinlichkeit dort an, wo wir es verbrauchen wollen: am Rad, im Ofen, in der Wärmepumpe. Der Motor eines E-Autos ist 2-4 mal effizienter als ein Verbrenner, weil er weniger Abwärme erzeugt. Eine Wärmepumpe kann aus 1 kWh Strom bis zu 4 kWh Wärme erzeugen, da sie mit der Umgebungstemperatur arbeitet. Ein Gasboiler wiederum verheizt das Gas und das war’s. Verbrenner-Autos sind eigentlich Heizungen auf Rädern. (AKWs sind gigantische Wasserkocher.) Wer also mit Grafiken vom Primärenergiebedarf herumwedelt und die Energiewende damit kritisieren will, sitzt einem Trugschluss auf. Es ist, als hätten sich die Leute in den 1920ern vor die ersten Autos gestellt und gefragt: „Und? Wie viel Hafer frisst das Ding jeden Tag?“ In Deutschland schmeißen wir wegen der Umwandlungsverluste jedes Jahr mehr als 30 Prozent unserer Primärenergie weg. Weltweit waren es vor der großen Elektrifizierung mehr als 50 Prozent. Mal eine Frage: Gehst du in den Supermarkt, öffnest die Packung mit zehn Eiern, siehst darin drei kaputte Eier und zahlst zufrieden? Du bist ja nicht blöd. Wir als Gesellschaft sind es schon. Wir haben 30 Prozent Verschwendung in unserem System eingebaut und hielten das so lange für normal, wie es keine Alternative gab. Aber jetzt gibt es eine. Wer mit Primärenergie-Charts herumwedelt oder Technologieoffenheit in Deutschland fordert, sagt eigentlich: „Lasst uns weiter verschwenden!“

Britain is presently generating 71% of electricity from renewables and is exporting some to boot. Nuclear plus renewables is presently 85% of all electricity being generated. Good things are possible. Ignore the boomer Murdoch press.

@tomhfh Freeze the price for everyone and increase the top rate of tax for those on six figure packages. It is exactly the same thing. It just means no compl x means testing and no cliff edges.

When looking at all the measures in the mini budget, it's important to remember the numbers. A £150bn spending commitment is a rather larger thing than a £2bn tax cut.

The government really haven't thought this through. This will have £10,000 to the cost of a house. That's £10k added to your mortgage. So you will end up paying around £20k (with interest) over 30 years for a heat pump that might last you 10 and solar that might last 20.
BBC Breakfast@BBCBreakfast

Developers will be required to install solar panels and heat pumps in all new homes in England as part of updated planning requirements published by the government. Energy minister Michael Shanks told #BBCBreakfast plug-in panels that homeowners can self-install on balconies will also be available in supermarkets in the coming months bbc.co.uk/news/articles/…

@JeremyNic666 @MDC12345678 It is noticable that no other country has sold its essential Infrastructure companies to foreign buyers. I mean, we are in the absurd position where much of our energy Infrastructure is owned by nationalised companies. They are just nationalised by other countries.

@EnergyObserver1 @MDC12345678 Is there something wrong with 'foreign companies'? I don't think so - do you? If so, you might like to have a think about the companies you would prefer UK to import gas from instead of producing it here - and the ownership of solar, wind turbine and battery supply chains.

@aDissentient The electricity market is an artificial creation with extremely complex rules. It was legislated into existence. Many other models exist that do not rely on marginal pricing. Indeed, before privatisation the CEGB used an average cost model.

@JeremyNic666 @MDC12345678 25 Years ago, North Sea oil was already in decline. British Energy (the Nuclear Generator) was bankrupt and had to be er-nationalised. The coal mines had almost all been closed. And PowerGen, National Power, and London electricity had all been sold to foreign companies. Terrific.

@MDC12345678 25 years ago really does seem like another world. Industry and consumers had secure, competitive energy supplies courtesy of market led energy policy and arms length regulation. Cumulative government interventions have undermined all of that, with predictably disastrous results.

@TMT_arabic That's because Iran doesn't own and control the waters in the strait so cannot charge, unlike the other countries mentioned. But mainly I would think not charging transit fees would be outweighed by all the terrorism, murder and tyranny.

The Iranian Foreign Minister addressing the world: ​Let me get one thing straight: Egypt charges $200,000 to $700,000 per transit through the Suez Canal. Large container ships or tankers can exceed $1 million. Panama charges $100,000 - $450,000 per transit. Large Neopanamax vessels cost up to $500,000 to transit the Panama Canal. Turkey charges fees for the Bosphorus Strait. Canada charges fees for the St. Lawrence Seaway. The United States charges fees for the St. Lawrence Seaway. Iran has refused to collect fees for the Strait of Hormuz for decades. They made it free! Despite the defamation, sanctions, and isolation—and yet you want me to believe that Iran is the "bad guy" here?

@7Kiwi @SteveAUK2 Yet we're assured by the brainboxes at @CarbonBrief that the reason China is building new coal fired power stations like there's no tomorrow is in order to not use them very much. But as their unevidenced theory is at variance with the data, I guess the data must be wrong :)

@7Kiwi When have we ever needed or wanted coal since? We are past the peak of coal: "Coal generation fell by 0.6% in the first half of 2025" The EU and US peaked way back in 2007, China and India have peaked.

@EnergyObserver1 @colinwalker79 Benefits for tax revenue and security of supply are worth having however marginal. Ditto reduced carbon footprint of UK gas v imported LNG. No impact on oil prices. I doubt gas price impact would be significant, but times when LNG is no longer marginal supply could increase.

Random Internet person: "But this one unsubstantiated datapoint about a single heat pump that 'someone I know' / my plumber mate / [insert random third-party here] says they're shit" How about real, near-realtime data from every single one of the many thousands of real Cosy heat pumps already installed by Octopus Energy in real homes? That's a really big dose of real. That's what we've done with the Cosy Heat Pump Fleet Performance Dashboard, released today. Let's talk about what the data says right now, not some hypothetical argument about what it might say tomorrow. Why hide behind marketing speak and hypotheticals when we can show you what the real data says about real heat pump installations in real homes? There aren't many energy suppliers out there who will go out of their way to put data like this out for the public to see. And when the request for this transparency comes right from the top, you know you're in the right place. It's a reminder of why I've spent the last 4+ years at Octopus. We did this around direct debit transparency with Balance Forecast, one of the first projects I worked on when I joined Octopus all those years ago. And we're still doing it today with this heat pump dashboard. It's been a pleasure working on this project and helping with the visualisations to help break down the frankly insane amount of raw data into insights around fleet-wide efficiency over time and how performance changes with the temperature. It also tops the list as the dashboard with the longest name that I've ever worked on…

@JeremyNic666 @colinwalker79 So you agree that is will have no impact on energy prices and a marginal impact on tax revenues even if the State appropriated all of the economic value. £50-80bn in a £3tn economy. Aka peanuts.

@EnergyObserver1 @colinwalker79 Whatever the pros or cons of Margaret Thatcher's time in office, successive administrations have (until now) followed similar policies on oil and gas production. I've never pretended anything about the size of UK oil or gas resources - perhaps you are thinking of someone else.

@JeremyNic666 @colinwalker79 Because it makes bugger all difference now. The ship sailed in 1979. And Mrs Thatcher drove it straight onto the rocks of right wing neo-liberal ideology. Im happy to do it now provided all rent goes to the state. And you stop pretending there is a huge resource left to exploit.

@EnergyObserver1 @colinwalker79 What has any of this got to do with a CURRENT policy decision to exploit/not to exploit UK oil and gas resources? This is a question about what should or should not happen NOW, not 50 years ago. I think we should maximise commercially viable UK oil and gas production - do you?
