UK’s Green Economy Surges to £77 Billion as Clean Energy Sector Expands Amid Employment Challenges

UK’s low carbon and renewable energy economy has achieved a significant financial milestone, with the Office for National Statistics confirming that turnover reached £77.0 billion in 2024 – a substantial increase of £8.1 billion compared with 2023. This represents continued growth in a sector that is increasingly central to Britain’s economic strategy and climate commitments.

The expansion reflects accelerating investment in clean energy infrastructure across the country. Over the past two years alone, the sector has expanded by nearly £8 billion annually, demonstrating the private sector’s confidence in renewable energy technologies and the government’s commitment to achieving net zero by 2050.

The financial expansion of the LCREE sector is underpinned by substantial progress in electricity generation. In 2024, renewable sources supplied over half of the UK’s electricity for the first time, reaching 50.4% of the national total – up from 46.5% in 2023. Wind power emerged as the dominant renewable contributor, generating 29.2% of UK electricity, whilst solar energy held steady at 5% of the mix.

More significantly, low-carbon sources – comprising renewables and nuclear combined – accounted for 64.7% of UK electricity generation in 2024, a record high. Low-carbon renewables alone (wind, solar and hydropower) generated 37% of UK electricity for the first time, overtaking fossil fuel generation at 35%.

This milestone represents a historic turning point for British energy infrastructure. The closure of Ratcliffe-on-Soar, the UK’s last coal-fired power station, in September 2024 marked the effective phase-out of coal from electricity generation. Natural gas, whilst remaining the single largest individual source, fell to 30.4% of the electricity mix – its lowest level since 2015.

However, the employment picture presents a more nuanced narrative. Whilst turnover expanded significantly, employment in the sector declined to 304,000 full-time equivalents in 2024 – a decrease of 13,000 positions compared with 2023. This apparent contradiction reflects wider trends within energy sectors where technological advances and increased operational efficiency can drive economic value whilst reducing headcount requirements.

The decline warrants scrutiny from policymakers concerned with ensuring that Britain’s clean energy transition generates sufficient quality jobs. The sector’s productivity has improved markedly, with each job now generating approximately £253,000 in turnover – a notable increase from previous years. Nonetheless, employment stability remains important for regional economies and workforce transition planning.

Contextualising these 2024 figures within longer-term trends reveals substantial sector development. In 2022, the LCREE generated £69.4 billion in turnover and employed 272,400 full-time equivalent workers. The jump to £77 billion and 304,000 employees demonstrates that despite the recent employment decrease, the sector remains substantially larger than it was just two years ago.

The sector’s export performance also strengthens Britain’s position in global clean energy markets. Exports from the UK’s low carbon and renewable energy economy reached £10.2 billion in 2022, positioning Britain as a significant exporter of green technology and expertise.

Achieving the UK’s net zero targets by 2050 will require substantially increased investment. Current assessments indicate that low carbon investment must scale to approximately £50 billion annually between 2030 and 2050, with the majority coming from private sector sources. The ONS figures suggest that private investment momentum is building, though accelerating the pace of capital deployment remains essential.

The lifting of the de facto onshore wind ban in July 2024 is expected to accelerate deployment rates in England, supporting further sector expansion. Similarly, offshore wind capacity continues to grow, with technological improvements driving down costs and improving energy generation efficiency.

The 2024 figures demonstrate that Britain’s clean energy transition is advancing both in terms of electricity supply and economic value creation. Whilst employment fluctuations require attention, the sector’s financial growth and unprecedented renewable electricity generation indicate that the fundamentals of Britain’s decarbonisation strategy remain robust. The challenge ahead involves sustaining employment growth alongside productivity gains, ensuring the transition benefits are distributed across regional economies and that sufficient skilled workers are available to support continued expansion.

Key Takeaways

• The UK’s low carbon and renewable energy economy reached £77.0 billion in turnover during 2024, up £8.1 billion year-on-year, reflecting accelerating clean energy investment
• Employment declined to 304,000 full-time equivalents from 317,000 in 2023, suggesting productivity improvements but raising questions about workforce transition planning
• Renewable electricity generation achieved a historic milestone, with low-carbon sources supplying 64.7% of UK electricity in 2024, whilst fossil fuels fell to record lows

What This Means for Kent Residents

For Kent residents and businesses, the expansion of the low carbon economy carries tangible implications. The sector’s growth supports skilled employment opportunities, particularly in engineering, project management and specialist technical roles – areas where Kent’s proximity to London and major research institutions creates advantages. With renewable energy infrastructure investment accelerating nationally, opportunities exist within the supply chain, manufacturing and installation sectors. Additionally, falling renewable electricity costs contribute to long-term energy price stability, benefiting household bills across the South East. However, residents and policymakers should monitor employment trends closely to ensure the transition generates sufficient sustainable jobs, particularly outside London and the South East, to prevent regional economic disparities. Cross-Channel trade through Kent’s ports may also benefit as European markets demand increased UK renewable equipment and technology exports.
