UK / AGILITYPR.NEWS / October 16, 2025 / Britain's greenest city has been revealed – and it’s generating a staggering 725% more electricity, from renewables like wind and solar, than it consumes. 

The findings come from a new renewable energy league table created by Power Saving Solutions, ranking every local authority in the UK by how much of their electricity demand is met from clean sources.

Lancaster took the crown, generating more than seven times the electricity it consumed. The Highland and North Yorkshire also rounded the top three, each producing far more green power than they use – exporting electricity to keep the rest of the UK running. 

On the flip side, central London boroughs were found lacking, producing next to zero of its electricity demand from renewable sources. The City of London generates just 0.05%, while Kensington & Chelsea (0.12%) and Westminster (0.13%) also appear at the very bottom of the national list.

The picture is clear: rural and coastal regions are powering the UK’s renewable revolution, while inner-city areas remain heavily reliant on imported electricity.

Key Figures 

The full league table is available below, but here is a snapshot into the most and least green regions of the UK

.

Top 3 local authorities

1. Lancaster — 725% renewable share (3,537 GWh generated vs 488 GWh consumed)
2. Highland — 517% (7,303 GWh vs 1,412 GWh)
3. North Yorkshire — 400% (11,287 GWh vs 2,825 GWh)

Bottom 3 local authorities

1. City of London — 0.05% renewable share (0.8 GWh vs 1,599 GWh)
2. Kensington & Chelsea — 0.12% (1.5 GWh vs 1,222 GWh)
3. Westminster — 0.13% (4.1 GWh vs 3,201 GWh)

Why this matters now

The league table lands just as ministers unveil sweeping reforms designed to turbo-charge Britain’s clean energy rollout:

• 20-year support contracts for new wind and solar projects, giving developers longer-term certainty.
• A revived onshore wind plan, aiming to unlock up to 45,000 jobs across England.
• The Clean Energy Industries Sector Plan, promising hundreds of millions of pounds for “build it in Britain” supply chains.

Despite this, the UK’s electricity system operator has warned the country could overshoot its 2030 climate targets by as much as one-third if renewable deployment does not speed up.

The results come at a critical moment for the UK’s clean energy future. Speaking to Reuters this month, Britain’s Secretary of State for Energy Security and Net Zero, Ed Miliband, sought to counter negative headlines:

“There’s lots of talk about countries stepping back from climate action and clean energy, but my message is, don’t believe the doomsters. When you look at what’s really happening, it’s actually a very, very different story.”

A spokesperson for Power Saving Solutions said:

“This league table tells a story of two Britain's. In Lancaster, Highland and North Yorkshire, renewables are generating more power than local people could ever need – these areas are fuelling the national transition and showing what’s possible when investment and space come together.

"But in the City of London, Kensington & Chelsea and Westminster, renewable generation is almost non-existent. That doesn’t mean these areas can’t act, but it does mean solutions will need to look different: rooftop solar, batteries, and smarter energy use in homes and businesses.

"And with the right battery storage in place, we can also make sure the renewable power we already generate isn’t lost, storing clean energy at peak times and releasing it back to the grid when demand is highest.”

They added:

“What’s encouraging is that momentum is growing. Government reforms to extend subsidies, revive onshore wind and invest in UK clean energy supply chains mean that Britain is at a turning point. These figures should spark conversation – not just about who’s top or bottom, but about how every community can play a part in a greener future. With smarter use of technology like storage and local renewables, no area is locked out of the clean energy transition.”
