What about "carbon emissions fell, except for buildings emissions ... Are we practitioners proud of ourselves, or is it someone else's fault?"

Are our emissions from Drax counted in the total, or are they ascribed to Canada or somewhere?

So there's some discrepancy for renewables 37+7=44% versus 50.8% but those are both generation estimates rather than the emissions Tom was referring to.

The French numbers for 2024 are out today - a fall of 1.8%, which isn't enough to meet the decarbonisation targets (they'd fallen 5.8% in 2023). Housing (-1.1%) and transport (-0.7%) are singled out as the biggest problem areas. Steps to tackle both are expected on Monday, after a meeting of the Ecological Council.

For housing, there was a 40% fall in energy-efficiency renovations, fewer heat pumps installed and a small rise in oil & gas heating boilers, now hit with 20% VAT from this month (new-build gas boilers were banned a few years ago). Seems that the fall in energy prices is taking part of the blame.

I may have missed it, but I've not seen any news of the UK Government doing anything urgently about it, like in France? So I guess it's not their fault?

Posted By: WillInAberdeenBest way to decarbonise buildings is simply to electrify them

Increasingly so. For a start - then comes the harder bit, because the only 'aspiration' that can save us is Nett Gain (not just Reduced Loss).

<blockquote>Any idea of the ROI you could expect?</blockquote>

Not forgetting that the ROI needs to include all the benefits to future generations

*subsidised loft roll. Can't edit anymore.

There's the financial ROI and the carbon ROI, most look at the financial ROI as part of the decision making process with the carbon ROI most of the time ignored.

I'M not sure about either ROI on my EV over my 30 year old Land Rover which I still have which is now kept only for dirty heavy work. I guess that becomes clearer down the line when resale values and life span become more apparent.

Absolutely no point in discussing the ROI with SWMBO for her new kitchen.

This document from DESNZ has a new set of figures for typical domestic energy use by Quarter:

https://assets.publishing.service.gov.uk/media/67e3eae39c9de963bc39b482/consumption-level-review-march-2025-methodology.pdf

"Since 2020 bills have been presented with fixed annual consumption levels of:
• 13,600kWh for Gas
• 3,600kWh for Standard Electricity, and
• 5,100kWh for Economy 7 (or time of use tariffs) Electricity

These levels provide an estimate of the average consumption across all UK households by taking the total consumption in the country and apportioning it to the number of households (by fuel).
This differs from Ofgem’s Typical Domestic Consumption Values (TDCVs) which provide the annual gas and electricity usage of a ‘typical’ domestic consumer, expressed as the median consumption value.

Providing bills based on a fixed mean consumption over time allows users to observe the impact of the change in price independent of changes in consumption arising from factors such as weather conditions, changes in energy efficiency and householder behaviour."

"New consumption levels were proposed in the December 2024 Quarterly Energy Prices release. No objections to these proposed levels were received, therefore from the March 2025 QEP, bills tables5 were presented for the first time using the revised fixed mean consumption levels of:

• 11,200 kWh for Gas
• 3,400 kWh for Standard Electricity, and
• 4,800 kWh for Economy 7 Electricity
These figures were used in the estimated final bills for 2024 along with a revised, consistent time series back to 2022."
