When will heating policy take gas emissions seriously? According to current heating policy, they are totally absent. If leaks were actually considered, we'd be looking at a carbon intensity of gas heating that would be much higher than 200g per kWh.

That might have been the case 10 years ago, but absolutely not true nowadays. Reversible units are dominant in residential aircon.

What do you mean "unidirectional"? They do heating and cooling...

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.

It's more that this is regressive. Does it feel fair?

The new £9,000 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.

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.

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.

I watched #dirtybusiness last night and as if by magic, Thames Water has cancelled my athletics training. The athletics club gets children active, it gets people from different backgrounds together. It's my community. I'm livid.

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).

Hawaii Gas is the sole gas utility in Hawaii and reports its own safety data. There's no independent monitoring body doing spot checks on their leak rates. Same situation. No independent oversight.

This is one of the reasons hydrogen won’t be piped simply through existing gas lines, despite what fossil gas companies claim. Hydrogen behaves very differently — it can leak through solid metal

If the gas networks still can't contain methane after more than a century of practice, why should we trust them with hydrogen?

Do you have access to a digital device? Good start. Next step is to use something called a search engine. Google will work. Type in: "does hydrogen cause warming?"

... then you might enjoy this chart, kindly shared by @twallinjames.bsky.social. It shows how an air-to-air heat pump can heat up a nearly 300 year-old church that is only used occasionally. Source: www.linkedin.com/posts/activi...
A graph showing how internal temperature rises inside a church building during the course of a day, once an air-to-air heat pump is switched on. The heat pump provides heat between roughly 3pm and 6pm, raising the temperature from 12C to a peak of 19C.

Why? Hydrogen has 1/3 the energy density of natural gas. Sites reported reduced power output, 2-6 year modification lead times, combustion instabilities, safety concerns from embrittlement/leakage, and increased NOx emissions.
