"Wind now accounts for approximately 23-25% of the UK’s energy,"
I think you are confusing energy and electricity. Wind solar and hydro are around 6% with around 3/4 being gas and oil.
"In 2022, the United Kingdom's total energy supply (TES) was primarily composed of natural gas, contributing 39.4%, followed by oil at 34.8%, nuclear power at 8.1%, and coal at 3.2%. Biofuels and waste contributed 8.9%, while other renewable sources such as wind, solar, and hydro collectively accounted for 5.6% of the energy mix."

Last time I looked we weren't using coal for transportation other than a few bits of nostalgic railway. Most oil consumption is transport related. I think it's generally accepted that home energy use is what's being discussed.
Nuclear definitely has a role so long as a government wants to pull it's thumb out of its arse and get on with it. Battery storage, wind and solar ftw. If uncle Bill can get it together traveling wave reactors could be a big part of the solution. https://en.m.wikipedia.org/wiki/TerraPowe r"> https://en.m.wikipedia.org/wiki/TerraPowerhttps://en.m.wikipedia.org/wiki/TerraPower
Insulate your walls with 120mm of wood fiber and you’ll reduce the heat loss through them by 60%+ assuming you have an insulated cavity wall already.
curious about this. have shied away from cavity wall insulation due to stories about damp etc. can you elaborate Ed?
I think the picture tells most of the story. What's missing is what covers it all up; usually plaster board or wood paneling. I've used a wooden frame fixed to the wall with all thread rods in chemical cement for walls that will be loaded, or screws and dowels for walls that aren't going to be loaded. If you are worried about the dew point falling in the middle of the insulation thickness than add a vapour barrier membrane on the inside under the plasterboard.
If the existing wall suffers damp other than condensation other insulating materials which won't rot are perhaps better - polyester wool for example, it's much nicer and easier to work with too but less eco.
Huh. Ta.
Well did say you were curious and asked elaborate. 🙂
I haven't shyed away from cavity wall insulation because those are insulating bricks with no cavity with similar thermal resistance to a cavity wall with insulation in the cavity. But both are only a third of the thermal resistance needed if you want to cut off the gas. So I've added some insulation on the inside.
