The North Sea Link connects GB to Norway's 85TWh+ hydro system via a 720km subsea cable. GB curtailed 10TWh wind in 2025. My modelling suggests that grows fourfold by 2035. That 'wasted wind' should be seen as a potential export to Norway.

Who controls the global regulatory agencies in charge of oil and gas? "The European Commission is considering suspending methane emissions penalties during energy supply crises after coming under intense pressure from US and the fossil fuel industry to dilute rules on leaks of the greenhouse gas."

If you were horrified watching elected leaders run & scramble because of gun violence, just imagine how my daughter Jaime felt in school running from an active shooter before she was killed. Now, become a part of the solution & only vote for people determined to address gun violence in America.

The new ยฃ9,000 BUS grant for oil and LPG homes looks regressive, and the data says it is. 54% of oil-heated property sales sit in the top 30% of UK house prices. Only 9% sit in the bottom 30%. Gas heats Britain. Oil heats the top of Britain.

Rising energy prices are pushing up inflation, especially in economies dependent on imported fossil fuels. The durable solution is structural: improve efficiency, accelerate electrification and scale up renewables. Energy policy is economic policy.

China is now the leading clean energy powerhouse with the West falling behind. The transition is inevitable; the key question is where and how fast it happens. I look forward to discussing this in Davos next week at the World Economic Forum, facilitating a live-streamed session on electrostates.

I've found that gas engineers are always friendly and happy to chat. The leak is coming from a 10 inch cast iron main. His words: "It stinks!" SGN have apparently visited this road many times (pointing to the various new bits of tarmac all over the shared path).

This is one of the reasons hydrogen wonโt be piped simply through existing gas lines, despite what fossil gas companies claim. Hydrogen behaves very differently โ it can leak through solid metal

Energy companies injected green hydrogen into Britain's gas grid and generated electricity - a "landmark development for the UK's climate ambitions." So we can just use blended hydrogen to power our old gas turbines? Problem solved? Not quite.

In the plots below, I've summed up the total HDD for each year. I've then compared some 30 years periods (1940 to 1969 and 1995 to 2024). It's not just a little bit warmer in the winter. It's significantly wamer. National parks chosen free from the 'heat island' effect that naysayers love.

In 2005 I spent 5 months in Ecuador investigating oil extraction. Around then German bank WestLB funded a new Andes pipeline despite past spills. What I saw was shocking and mostly unseen. This 2022 video shows just one example of repeated spills poisoning rivers and communities.

This is a methane plume detected over a seabank power station. I had to extract this image via a freedom of information request. Fossil fuel companies will tell you that they can safely bury carbon dioxide from burning gas. How? They're not even handling methane competently.

Do some reading on "leveraged buyouts and UK national infrastructure". It's absolutely maddening. Private equity has managed to turn the water and gas networks into interest-only buy to lets, and we're all paying the bills... financially and environmentally.

If Ed Miliband really has decided against zonal pricing, he has just cost Labour 100 seats at the next election. Zonal could be introduced by 2028 and would instantly stop natgas setting wholesale power prices across the UK 96% of the time. Should be a no-brainer.

Post-Spending Review: Govt prioritises ยฃ9.4bn for CCUS, but 26% of UK gas is high-emission US LNG. Billions spent burying emissions, ignoring methane leaks & gas production damage in the USA. Is our current gas network good at handling gases? Short answer: No.

Gas networks seem to already struggle with methane - so how can they hope to safely handle hydrogen? Here's a plot of reported gas leaks overlaid with the proposed hydrogen network. Food for thought for the residents of Newcastle, Middlesbrough, or Bishop Auckland.

Do you think the emissions for gas heating are solely from burning the gas delivered to your home? Think again. Gas networks leak; as you can see in the footage. 1 million tonnes of carbon dioxide is equivalent to almost 600,000 return flights between London and New York.

Does the electricity market by design induce frequency oscillations? Think about it. 1) Demand is a continuous curve. It is inherently driven by random human behaviour. 2) Generation is generally dispatched in blocks.
