Oil Industry Consultant Joins #Climate Denial Group Run by Tory Peer. Kathryn Porter, an “independent” energy expert, has become a trustee of the Global Warming Policy Foundation. Kathryn Porter, a consultant to the fossil fuel industry and a prominent critic of emissions reduction policies, has joined the UK’s foremost climate science denial group. Porter appears frequently in the media as an “independent” expert on energy issues and has been interviewed on the BBC, LBC, GB News, and TalkTV, while her research is often covered in conservative media. She also writes a column for The Telegraph, and in recent weeks she spoke on energy panels at both Labour and Conservative party conferences. Porter’s consultancy Watt-Logic advises the oil and gas industry. Its website states that she works for “businesses with projects across the electricity, gas and oil industries”, including “clients with conventional energy assets including gas-fired power stations, gas storage, upstream oil and gas production and [Liquefied Natural Gas]”.

Economics is fundamentally political. We cannot escape this fact.
The so-called “free market” is constructed by laws, maintained by institutions, and enforced by states.
The choice between austerity and stimulus reflects deeper beliefs about responsibility, fairness, and social obligation.
The mandates of central banks are products of political decisions. The emphasis placed on price stability in Western central banks rather than, say, regulating private finance reflects value judgments as well as political lobbying.
One of the biggest differences between mainstream economics and heterodox economics is that the former often disguises political choices as technical ones.
Economics has never been, and never will be, a value-free science, no matter how much today's mainstream economics tries to present it that way.
At its core, economics is shaped by ideologies, human morality, competing interests, social norms, and political priorities. Pretending otherwise does not make economics more rigorous. It just makes it more dangerous.

📊 The 2016 Brexit electorate no longer exists.
Peter Kellner has updated the sums using YouGov and ONS data.
Since 2016:
🔹 Around 3.8m Leave voters have died, against 2.1m Remain voters.
🔹 Around 7m new voters have reached voting age, overwhelmingly pro-European.
🔹 Around 5m voters have changed their minds 👉roughly three-quarters of them moving from Leave to Rejoin.
His estimate of how Britain would vote now:
🇪🇺 REJOIN: 20.0m 👉 63%
🇬🇧 STAY OUT: 11.8m 👉 37%
A majority of almost 9 million.
Brexit happened. Britain has lived with it for a decade.
But democracy does not freeze the electorate in 2016 forever.
The question is what Britain wants now not what it indicated in 2016.
📊 The Brexit majority hasn’t just slipped 👉it’s vanished. Completely.
This chart from Peter Kellner/YouGov shows:
• 5 million 2016 voters have died
• New young voters back Rejoin by 5:1
• 29% of Leave voters now want to rejoin
• Net result: Rejoin 19.8m vs Stay Out 11.7m
➡️ An 8 MILLION majority for Rejoin.
Britain is now a pro-EU country.
The only people keeping Brexit alive are politicians who benefit from the damage.
I agree : we need to optimise our system differently & as @g__j says ‘not with the tools of yesterday’. The evidence shows this is cheaper for customers; better for security & env. YET lobbies still fight any changes. Govt has to step in to sort this out given Ofgem inertia
You can't run a system with millions of variable consumption and generation and storage devices the way you ran it when you had 150 fossil fuel generators and a handful of nukes.
It's not the new technology (wind, solar, batteries, EVs) that's the issue - it's the total failure to change the way we manage the system.
This is why locational wholesale market (which is automatically dramatically more flexible) was so powerful - and is increasingly used in the OECD. We need decentralised signals so the system self-optimises.
Octopus already processes 300,000 data points a second to do this for the many GW we control - but the brute force of the main system management just doesn't have this granularity.
It is increasingly urgent to reform our electricity system. These control room issues, the £50m spent balancing the system in a single day, the £3bn a year on curtailment, the prospect of £7-9bn a year of curtailment by 2029/2030.
It's all avoidable but not with the tools of yesterday

This is a big deal - The first time England has had a severe drought in modern history - 100 years. It’s another aspect of the failure of water privatisation - private companies, mostly foreign owned and based, are not capable of providing the water service (and sewage) that we need, that’s abundantly clear.
We need a change of approach.
Thatcher was wrong, the private sector does not do it best in all cases - defo not in a monopoly on a vital national service.
Time to take back control of our water. Not ownership necessarily (unless they fail) - just control.

The next step for Ukraine and the European Union should be to begin consultations on gradually, but relatively quickly, replacing Starlink across military, law enforcement, intelligence, and government institutions with European alternatives, even if that means subsidizing.
ProfCatherineMitchell retweeted
Considering the repeated calls to replace Starlink in the EU, followed by the usual snarky comments, mostly from Americans, about how SpaceX is "irreplaceable" and Europe is supposedly incapable of competing, I think it's worth looking at some facts.
First of all, EU countries have launched hundreds of satellites over the past decade, with annual deployments growing from just 16 in 2015 to 135 in 2025. Eutelsat OneWeb already provides continuous coverage across Europe with more than 600 satellites
On top of that, the EU is developing IRIS², a constellation of ~350 satellites, with the first launches scheduled for 2029. The EU's GOVSATCOM programme has already been operational since January 2026, pooling satellite capacity from member states for secure government communications.
Now, let's get to the actual argument. Is Europe behind SpaceX, with its thousands of satellites in orbit? Absolutely. At the moment, it's not even close. Starlink has significantly cheaper consumer terminals, much greater network capacity, a larger constellation and a far more accessible service for ordinary customers. No argument here.
But that's also part of the problem.
Starlink is simply a better and more affordable product for most consumers right now, so customers and government contracts naturally gravitate towards SpaceX, making it harder for European competitors to attract the revenue and investment needed to catch up.
Let's also not pretend SpaceX appeared out of nowhere. It benefited from decades of American aerospace infrastructure, NASA research, publicly funded programs and government contracts, alongside its own substantial private capital
Putting a European startup, or even a single country's space agency, against that entire ecosystem is a losing proposition from the beginning.
But why should it stay that way?
Europe already has the aerospace industry, launch facilities, technological expertise and financial resources to develop a competitive alternative.
To launch satellites successfully and cheap you need to decrease the launch cost. Currently, European rocket Ariane 6 is generally more expensive than Falcon 9, and Europe still lacks a comparable operational reusable launcher. But projects like Themis and Maia are already in development.
If Europe keeps pouring money into SpaceX, how exactly do you expect these European projects to become competitive?
The same applies to satellite terminals. SpaceX has excelled at mass-producing consumer-friendly equipment costing a few hundred dollars, while comparable OneWeb equipment can cost several thousand.
But that advantage comes from economies of scale, production efficiency, mass adoption and, sometimes, subsidising hardware to gain market share. You can't have mass adoption if you mass adopt Starlink
Europe doesn't need to replicate Starlink's entire global network to build a viable alternative. The objective is sufficient coverage, capacity and reliability across Europe and neighbouring regions, not necessarily every random island in the Pacific or remote village in the Brazilian Amazon - something that SpaceX does much better. That's a much more realistic objective than immediately matching Starlink worldwide.
There are several ways to achieve this: direct investment, research funding, initial subsidies, long-term government contracts and procurement policies prioritising European satellite providers wherever feasible, particularly for critical infrastructure.
In strategically sensitive areas, I'd go even further and eliminate dependence on SpaceX entirely wherever a viable European alternative exists.
Which brings us to national security.
Starlink is an American commercial system subject to US jurisdiction, while Starshield is specifically designed for US government and military customers. Starlink's own terms allow the company to suspend services following requests or orders from government agencies.
Now imagine a hypothetical scenario where the US attempts to annex Greenland militarily. Would you really want critical European communications infrastructure dependent on an American company that could could simply switch off everything on political demand? You simply cannot outsource your country's critical communications infrastructure to a foreign provider and pretend there are no strategic risks involved. I don't like writing it, but US is not a reliable partner.
And beyond security, it's also about money and long-term economics.
European money, investment and talent should stay in Europe, not continuously flow to America. Do you want European aerospace graduates to have actual career opportunities in Europe, instead of feeling they need to move to the US?
Do you want European companies building rockets, satellites, manufacturing facilities and research centres, creating skilled jobs and attracting investment?
None of that happens if your entire strategy is to keep buying American Starlink terminals while complaining that European alternatives are too expensive or technologically inferior.
There's a massive difference between saying Europe cannot fully replace Starlink today and claiming that Europe is fundamentally incapable of developing a competitive alternative, while quoting memes about muslim immigrants and plastic bottle caps.
And if Europe keeps financing its competitors instead of building its own capabilities, SpaceX will indeed remain "irreplaceable". Not because Europe can't compete, but because it is not committed to the competition.

I'm proud to report that for the first time in history, the @UN has achieved gender parity across all senior leadership, headquarters & professional staff.
We removed barriers, challenged assumptions & refused to accept that power must look as it always has. And we never compromised on quality & competence.
If the UN can do it, so can governments, parliaments & businesses everywhere.

Aalborg now has 241,000 m³ of hot water storage, the largest in Denmark, plus 150 MW of electric boilers and a 177 MW seawater heat pump.
That's 217 MW of flexible demand, holding one to three winter days of heat.
