How clean is the power where you are
Electricity is cleaner in some parts of Britain than others, depending on what is generating nearby. The gap between the cleanest and dirtiest regions is usually far wider than most people expect.
At 19:27 GMT on 7 November 2026, the cleanest electricity in Great Britain was in North Scotland at 0 gCO₂/kWh, and the most carbon-intensive was in South West England at 393 gCO₂/kWh. These are forecasts for the current half hour.

What this means
Electricity all mixes together on the same network, so no one literally receives power from a single wind farm. What these figures describe is the mix generated and imported within each region, which is the fairest way to attribute emissions to the electricity used there.
Regions with a lot of wind or nuclear nearby - most of Scotland, the north of England - sit far lower than areas that lean on gas. The figures are a forecast for the half hour in progress, and they move throughout the day as the weather and demand change.
Common questions
Why is electricity cleaner in Scotland?
Mostly because it has a lot of wind and relatively little local demand. Areas that rely more on gas show higher figures.
Does this mean my power comes from a local wind farm?
No. Everything mixes together on the same network, so you can't trace your power back to one wind farm. The figure describes the mix generated and imported in your region.
Why do you only ask for part of my postcode?
The first part is enough to find your region, so we don't ask for the rest.
