Designing Energy Efficiency Policies to Enhance Affordability
Examples from G7 countries Energy affordability has emerged as a critical concern in the context of rising global energy prices and growing inequality in energy access. Lower-income households spend a significantly higher share of their income on energy than wealthier households, leaving them exposed to price shocks and especially vulnerable when energy prices increase. Energy efficiency can play a key role in delivering lower energy bills, reducing emissions, and enhancing resilience. However, ensuring that all households benefit requires targeted, inclusive policy design.This issue was a central focus of an IEA workshop held in January 2025 with G7 country…

Clean Energy Technology Supply Chain Data Executive summary
Energy security in the Age of Electricity is inextricably linked to securing the supply chains for clean energy technologies and the equipment and materials used to manufacture them. As countries continue to pursue energy transitions and make investments in the deployment and manufacturing of these technologies – guided by industrial strategies – a detailed understanding of their supply chains has an essential role to play.The availability of good-quality, timely data is crucial to understanding clean energy technology supply chains and addressing vulnerabilities. Risks to supply chains can arise from interdependencies across technologies and between geographies, among other factors. Today, the…

Rare Earth Elements Executive summary
Rare earth elements have rapidly moved to the forefront of the energy and economic policy agenda Rare earth elements play a crucial role in a wide range of strategic applications, from energy, transport and artificial intelligence (AI) technologies to aerospace, medical and defence systems. The wide range of applications, combined with highly concentrated supply chains, has elevated their importance in both energy and broader economic security discussions. Though relatively plentiful in the Earth’s crust, this set of 17 elements have garnered the label “rare” because economically viable concentrations are uncommon and they are seldom found in pure form. Their chemical…

Ukraine’s Energy Security
A pre-winter assessment As Ukraine enters its fourth winter of war, ensuring that residents retain reliable access to heat and power is of the utmost importance. While Ukraine made strong strides in rebuilding and strengthening the resilience of its energy system this past spring and summer, the situation remains fragile, and the risk of huge disruptions and widespread destabilisation remains – particularly as Russia expands the scope and sophistication of its attacks.This analysis builds on the IEA’s September 2024 report, Ukraine’s Energy Security and the Coming Winter. It provides an update on the latest developments through October…

Global Energy and Climate Model
Scenario analysis of future energy trends Global Energy and Climate Model Over the past four years, the IEA has worked to develop a new integrated modelling framework: the IEA’s Global Energy and Climate (GEC) Model. This model is now the principal tool used to generate detailed sector-by-sector and region-by-region long-term scenarios across IEA's publications, including the World Energy Outlook series and Energy Technology Perspectives series.In 2021, the IEA adopted for the first time a new hybrid modelling approach relying on the strengths of both models. The integrated framework of the IEA’s Global…

Energy security
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores energy security. Why is energy efficiency important for energy security? Energy efficiency can help mitigate energy security risks by reducing the reliance on fossil fuel imports, improving grid reliability, and acting as a buffer to supply shocks. Key facts Efficiency gains from the last two decades avoided the need for 20% more fossil fuel imports in IEA countries. Energy efficiency and demand response can support grid reliability by reducing peak demand. For instance, more efficient air conditioners in India could lower the impact of heatwaves on…

Gas Market Report, Q2-2026
This edition of the IEA's quarterly Gas Market Report provides a comprehensive review of developments during the 2025/26 heating season and a special spotlight on the effects of the war in the Middle East on international gas markets. Amid the major supply shock caused by the disruptions to shipping through the Strait of Hormuz and attacks on regional energy infrastructure, it examines the conflict’s implications for gas supply and demand at both the regional and global levels. The report also analyses the consequences for storage, shipping and prices – providing critical insights on evolving market trends.The loss of nearly…

Critical Mineral Traceability for Energy and Economic Security Executive summary
Risks to energy and economic security from high levels of concentration in critical mineral supply chains became a reality in 2025. All of the IEA’s six focus minerals – copper, lithium, nickel, cobalt, graphite and rare earth elements – are set to see strong demand growth, driven by their central role in energy and strategic industrial applications. Yet diversification has lagged demand, with processing and refining remaining highly concentrated. Risks from concentration materialised in 2025 as new export controls threatened the supply of materials critical to strategic and economically important industries.Recent years have seen a proliferation of new policies and…
