The UK Energy Security Summit 2025, co-hosted by the UK Government and the International Energy Agency (IEA), took place in London on 24–25 April 2025.
“Energy security is national security” – Kier Starmer at the Energy Security Summit
The summit brought together leaders from over 60 countries and 50 major energy companies. This represented a united step towards redefining energy security in response to global challenges. Discussion centred around geopolitical tensions, the climate crisis, and rapid technological shifts.
Purpose of the UK Energy Security Summit
The UK Energy Security Summit was convened to develop a coordinated international response to growing energy security threats. It reflected a shared understanding that energy security underpins national security, economic resilience, and the global transition to clean energy.
Key Topics at the Summit
- Energy security as national security: UK Prime Minister Keir Starmer announced a £300 million investment in the offshore wind supply chain. This supports the UK’s target of 100% renewable electricity generation by 2030. This underlines the UK’s ambition to strengthen domestic energy security while advancing towards net zero.
- Diverging transatlantic energy strategies: The UK and EU advocated for an accelerated clean energy transition. US representatives raised concerns over vulnerabilities linked to over-reliance on renewable technologies and critical mineral supply chains dominated by China.
- The role of nuclear energy: Nuclear power’s importance in a resilient energy mix was emphasised. Discussions raised between the UK and France on consolidating financial packages for major nuclear projects. This is to include Hinkley Point C and Sizewell C.
- Critical minerals and supply chain diversification: Delegates stressed the urgent need to diversify supply chains for critical minerals, essential for clean energy technologies like battery storage. This aims to reduce reliance on single-country suppliers and strengthen global energy security.
- Broadening the definition of energy security: The summit expanded the conversation beyond traditional supply concerns. Discussions pivoted to include cybersecurity, climate resilience, and the integration of decentralised energy systems.
- UK/EU energy collaboration: The UK and European Union reaffirmed their commitment to closer cooperation through initiatives like the Global Clean Power Alliance and the EU’s Global Energy Transition Forum, aiming to accelerate the deployment of low-carbon solutions.
Key Outcomes
The UK Energy Security Summit underlined international momentum towards building diversified, resilient, and sustainable energy systems. While geopolitical differences remain, there was broad consensus on the need for greater international cooperation, investment in clean energy, and supply chain resilience.
This marked a defining moment in the evolution of energy security and centred the UK in the global discussion.
