How Much of the UK’s Energy Is Renewable? (2025-2026 Statistics)
The UK has made faster progress on renewable energy than almost any other major economy. But the headline figures can mislead depending on which question you’re actually asking, and that distinction matters more than most coverage suggests.
This guide breaks down the latest statistics, explains what the numbers actually mean, tracks progress against government targets, and covers what all of it means for businesses.
The Most Important Distinction: Electricity vs Total Energy
This is where most reporting on UK renewable energy causes genuine confusion.
There are two ways to measure the UK’s renewable share, and they produce very different numbers:
Share of electricity generation: how much of the electricity flowing through the grid comes from renewable sources.
Share of total energy consumption: how much of all energy used across the economy, including electricity, heating, transport, and industrial processes, comes from renewable sources.
Measure | Renewable Share (2024-2025) |
Electricity generation | ~52.5% |
Total energy consumption (all sectors) | ~16-25% |
The gap exists because electricity is only one slice of how the UK uses energy. Heating homes and offices (mostly gas), running vehicles (mostly petrol and diesel), and powering industrial processes all remain heavily dependent on fossil fuels. Renewable alternatives in those sectors are far less developed than renewable electricity.
The UK has made a genuine transformation in its power sector. The broader energy transition, particularly in heating and transport, is still at an early stage.
UK Renewable Electricity Statistics: Latest Data
Renewable sources now generate the majority of UK electricity. Key figures from the most recent government data:
Renewable Source | Share of UK Electricity Generation |
Wind (onshore and offshore) | ~30% |
Biomass and bioenergy | ~7.1% |
Solar PV | ~6.9% |
Hydropower | ~1.1% |
Total renewables | ~52.5% |
Nuclear (low-carbon, not renewable) | ~14% |
Gas | ~28% |
Coal | 0% |
Two milestones are worth highlighting here.
In 2024, the UK became the first major economy in the world to eliminate coal from its electricity generation mix entirely. Coal once powered over 70% of UK electricity. It now contributes nothing.
And for the first time in the country’s history, renewable sources collectively generate more than half of all electricity. Wind alone accounts for nearly 30%, more than any single source including gas.
In Q3 2024, the UK generated 32.2 terawatt-hours of renewable electricity, up 6.5% from the same quarter in 2023. One terawatt-hour equals one billion kilowatt-hours, the unit used on your energy bill.
UK Total Energy Mix: The Wider Picture
When you include heating, transport, and industry alongside electricity, fossil fuels still account for roughly 75% of the UK’s total comprehensive energy demand. That’s not a failure of ambition. It reflects how much harder it is to decarbonise those sectors compared to power generation.
Heating: Most UK homes and businesses heat with natural gas. The gas grid supplies approximately 85% of UK households for space heating and hot water.
Transport: Despite rapid EV growth, the majority of UK vehicles still run on petrol or diesel. Road transport alone represents a significant portion of total UK energy use.
Industry: Many industrial processes require high-temperature heat that remains difficult and expensive to generate from electricity or renewable alternatives.
Sector | Primary Energy Source | Renewable Share |
Electricity generation | Wind, gas, nuclear | ~52.5% renewable |
Heating (homes and businesses) | Natural gas | Low, biomethane growing |
Road transport | Petrol and diesel | Low, EV share growing |
Industry | Gas, oil, electricity | Mixed |
Renewables’ share of gross final energy consumption, the official DESNZ measure, was approximately 16-22% in 2024 depending on methodology.
How the UK’s Renewable Share Has Grown Over Time
The growth in UK renewable electricity over the past 15 years is one of the most dramatic energy transitions any major economy has achieved.
Year | Renewable Share of UK Electricity |
2010 | ~7% |
2015 | ~25% |
2019 | ~37% |
2021 | ~40% |
2022 | ~41.5% |
2023 | ~44.9% |
2024 | ~50.4-52.5% |
This growth has been driven primarily by offshore wind. The UK now operates one of the largest offshore wind fleets in the world, with over 14 GW of installed capacity as of 2024.
Solar has also grown substantially, contributing around 6.9% of electricity in 2024, up from near zero in 2010. The cost of solar panels has fallen by over 90% in that time, making commercial and industrial installation increasingly viable for businesses of all sizes.
Wind Power: Now the UK’s Largest Energy Source
Wind is now the single largest source of electricity in the UK, ahead of gas, nuclear, and everything else combined.
Onshore wind generates approximately 12-14% of UK electricity. Planning restrictions in England have historically limited onshore expansion, though the government has moved to ease those rules in recent years.
Offshore wind generates around 16-18% of UK electricity and is the primary engine of renewable growth. Major projects include:
- Dogger Bank: already the world’s largest offshore wind farm at full build-out, generating enough electricity for approximately 6 million homes
- Hornsea 3: one of the largest offshore wind farms under development anywhere in the world
The government’s target is 50 GW of offshore wind capacity by 2030, more than three times current installed capacity. The Crown Estate’s offshore wind data tracks the pipeline of projects in development.
UK Government Renewable Energy Targets
Target | Detail | Deadline |
Clean electricity | 100% zero-carbon generation | 2030 |
Offshore wind capacity | 50 GW | 2030 |
Net zero economy | No more emissions than are removed | 2050 |
Coal phase-out | Full elimination from electricity mix | Achieved 2024 |
Heat pump installations | 600,000 per year | 2028 |
EV-only new car sales | No new petrol or diesel cars | 2035 |
One clarification worth making: the 2030 clean electricity target doesn’t require 100% renewables specifically. Nuclear, which is low-carbon but not renewable, will continue to play a role. Hinkley Point C is under construction, and plans for small modular reactors (SMRs) are in development. The UK Government’s clean energy plans sets out the full strategy.
Renewable Energy by UK Region
Renewable generation isn’t evenly spread across the country. Geography and wind patterns matter considerably.
Scotland generates significantly more renewable electricity than it consumes, exporting surplus south to England and Wales. In some periods, Scotland’s renewables exceed 100% of its own electricity demand. Wind and hydro dominate.
Wales has strong wind resources and growing offshore wind development along its coastline.
England leads on solar generation, particularly in the south where sunshine hours are higher, and hosts the majority of UK offshore wind infrastructure.
Northern Ireland operates within the Single Electricity Market (SEM) linked to the Republic of Ireland, with strong onshore wind generation contributing a growing share.
What This Means for UK Businesses
The shift in the UK’s electricity mix has direct practical consequences for how businesses buy and use energy.
Green Tariffs Are Now Mainstream
Because renewables generate the majority of UK electricity, suppliers can credibly offer 100% renewable electricity tariffs backed by REGO (Renewable Energy Guarantee of Origin) certificates at prices comparable to standard tariffs. Green electricity is no longer a premium niche product. It’s increasingly the default option for businesses with sustainability commitments.
Fossil Fuel Price Volatility Makes the Case Stronger
The 2021-2023 energy crisis, driven largely by gas market disruption, pushed UK business energy bills to record levels. The underlying problem was the electricity market’s dependence on gas-fired generation, which sets the marginal wholesale price even when renewables are generating at full capacity.
As renewable capacity expands and gas’s share falls, that link weakens. Businesses that lock into fixed renewable tariffs during lower-price periods gain some insulation against future fossil fuel price spikes.
Time-of-Use Tariffs and Smart Procurement
With renewables exceeding half of UK electricity, wholesale prices now fluctuate more sharply throughout the day, falling when wind or solar output is high, rising when it drops. Businesses with smart meters and half-hourly settlement can access time-of-use tariffs that allow them to shift energy-intensive activity to periods of high renewable generation, when prices are at their lowest. Sometimes near zero. Occasionally negative.
Sustainability Reporting Requirements
Growing numbers of businesses are required to report Scope 2 emissions under frameworks including SECR, TCFD, and supply chain due diligence requirements. Switching to a verified renewable electricity tariff reduces reported Scope 2 emissions to near zero, a material benefit for businesses with public sustainability commitments or investor ESG expectations. The Carbon Trust’s guidance on renewable electricity procurement covers the verification process in detail.
Frequently Asked Questions
What percentage of UK electricity comes from renewable energy?
Approximately 52.5% as of 2024-2025. Wind is the largest single contributor at around 30%.
What percentage of total UK energy is renewable?
When heating, transport, and industry are included alongside electricity, renewables account for approximately 16-22% of gross final energy consumption. Fossil fuels still supply around 75% of total energy demand across all sectors.
What is the UK’s largest source of renewable energy?
Wind power, particularly offshore wind. Offshore wind generates approximately 16-18% of UK electricity, with onshore wind contributing a further 12-14%.
Has the UK stopped using coal?
Yes. Coal was eliminated from the UK’s electricity generation mix in 2024, making the UK the first major economy to achieve this. Coal once provided over 70% of UK electricity.
Why is renewable energy only 16% of total UK energy if it’s 52% of electricity?
Because electricity is only one part of how the UK uses energy. Gas for heating and petrol or diesel for transport make up a large share of total consumption, and both remain dominated by fossil fuels. Decarbonising heat and transport is the next major challenge.
Does switching to a renewable electricity tariff mean I’m using 100% renewable energy?
It means your electricity usage is matched by verified renewable generation through REGO certificates. Your gas usage is a separate matter and would require a green gas tariff or carbon offsetting.
Final Thoughts
From under 10% in 2010 to over 52% in 2024-2025, with coal gone and offshore wind now the country’s single largest power source, the transformation of the UK’s electricity sector is one of the more remarkable industrial shifts of the past two decades.
The broader picture is more complicated. Heating and transport still run overwhelmingly on fossil fuels, and decarbonising those sectors at scale is the harder, slower, more expensive part of the journey to net zero by 2050.
For businesses, the practical message is straightforward: renewable electricity is mainstream, competitively priced, and independently verified. The case for switching to a green business electricity tariff has never been more clear-cut.
