The UK Energy Mix Has Tipped in Favour of Renewables

22nd December 2025The UK has entered a new energy era. And this time, it’s not just a policy ambition. It’s a measurable, accelerating shift that’s already playing out on the National Grid.
In the first half of 2024, low-carbon sources generated a truly impressive 74.1 per cent of Great Britain’s electricity. Wind overtook gas as the single largest contributor, accounting for 39 per cent of all power generation across the country.
By the second quarter of 2025, renewables alone delivered 56 per cent of the country’s electricity to mark a new record for that period.
From these figures alone, it’s clear that fossil fuels are in retreat. With natural gas falling below a quarter of generation and coal now virtually absent, the UK energy mix is well and truly moving in favour of renewables.
This rapid transformation has direct consequences for one group in particular: landowners.
As demand for renewable generation sites surges and planning rules evolve, the question is no longer whether your land can support clean energy. It’s whether you’ll act before the opportunity moves past you.
Is This a Large Shift in the UK Energy Mix?
For years, the UK has positioned a move to low-carbon energy as a goal. And this was hitting net zero by 2050, with decarbonised electricity by 2035.
In 2025 alone, we’ve seen the grid operate on clean electricity for hours (sometimes days) at a time. The record currently stands at 87 hours, which is up from an already-impressive 64.5 hours in 2024.
The Great British Energy Act passed earlier this year has created a publicly owned vehicle to invest directly in new renewable infrastructure. And to support this, planning permission for onshore wind and solar is starting to move quicker.
This has only been helped by a clearer national policy framework and removing the de facto onshore wind ban back in 2024.
From a landowner’s perspective, this isn’t just about infrastructure. It’s about land value, grid capacity and a sharp increase in interest from developers seeking viable sites.
As the availability of suitable sites tightens even further, landowners are in a strong negotiating position.
Clean Power Needs Land
The shift in the UK energy mix is making one thing clear: the energy system of the future will be far more decentralised.
It’ll depend on thousands of sites across the country generating, storing and exporting power.
To put this into perspective, let’s take a quick look at the UK’s energy mix as of late 2024.
These figures mean that demand for well-positioned land is growing in a big way. And that’s particularly true in areas with access to the National Grid, transport routes or gently sloping topography that’s perfect for renewable energy projects.
Developers are expanding their search areas, local authorities are setting ambitious targets and lease rates are generally increasing to match demand. Land that might have been considered less-than-ideal five years ago could now be economically viable.
But the competition isn’t only between developers – it’s between landowners. Grid capacity is finite and the National Grid is increasingly issuing offers on a first-come, first-served basis.
Those who begin feasibility assessments now are better placed to secure grid access and attract interest from great developers.
A Changing UK Energy Mix Means a New Set of Decisions
This moment requires a shift in thinking for landowners.
Historically, energy was more of an external thought and something that happened elsewhere. Today, it’s a direct land use decision. A new income stream. A chance to unlock value without selling up or changing the core use of a site.
Whether you’re managing a farm, overseeing a rural estate or sitting on disused commercial land, the clean energy transition is presenting a new kind of opportunity. And it’s one that doesn’t just diversify income, but positions you as a core contributor to national infrastructure.
The Window Is Open, But It Won’t Stay That Way
There’s a tendency (especially in regulated industries) to assume that a rising trend will always leave room for late adopters.
But energy infrastructure doesn’t work that way. Grid capacity is limited. Planning quotas are enforced locally. And once a site is connected or a region hits capacity, that window can close.
The most strategic landowners are acting now. They’re commissioning feasibility scans, reviewing lease models and initiating conversations with developers or advisers that may end in option agreements.

So, Strike While the Iron’s Hot
The data is no longer speculative, and the UK energy mix is changing at an incredible pace.
Wind is now the backbone of the Grid, and solar is rising fast. Battery storage is also going into mainstream deployment. And policy, public opinion and technology are all becoming aligned with clean power in an extremely positive way.
If you own land (especially in rural, semi-rural or grid-adjacent areas) you’re not just a bystander to that change. You’re in a position to power it.
The opportunity is tangible, time-sensitive and backed by some of the clearest market signals we’ve seen in a generation.
The next move is yours.
