The Implications of Oil and Gas Field Decline Rates
Much attention today focuses on uncertainties affecting the future evolution of oil and natural gas demand, with less consideration given to how the supply picture could develop. However, understanding decline rates – the annual rate at which production declines from existing oil and gas fields – is crucial for assessing the outlook for oil and gas supply and, by extension, for market balances.The International Energy Agency (IEA) has long examined this issue, and a detailed understanding of decline rates is at the heart of IEA modelling and analysis, underpinning the insights provided by the scenarios in the World Energy Outlook.This new…

Oil Market Report - April 2025
The IEA Oil Market Report (OMR) is one of the world's most authoritative and timely sources of data, forecasts and analysis on the global oil market – including detailed statistics and commentary on oil supply, demand, inventories, prices and refining activity, as well as oil trade for IEA and selected non-IEA countries. Highlights Global oil demand growth for 2025 has been revised down by 300 kb/d since last month’s Report to 730 kb/d, as escalating trade tensions have negatively impacted the economic outlook. Growth is expected to slow further in 2026, to 690 kb/d, but…

Key Questions on Energy and AI
Following the publication of the IEA’s landmark Energy and AI report in 2025, this report examines how the energy and AI nexus has evolved amid surging investment in data centres and rapid advances in model capabilities. Drawing on fresh datasets and analysis, it explores where electricity demand is rising, how quickly grids and supply chains can respond, and what these shifts mean for energy security, affordability and sustainability.

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…

Cost of Capital Observatory
Tracking the cost of capital for clean energy projects in emerging and developing economies The Cost of Capital Observatory is an initiative from the IEA, the World Economic Forum, ETH Zurich and Imperial College London. The aim of the Observatory is to increase transparency in the energy sector and inspire investor confidence, especially in emerging and developing countries where data on financing costs is scarcer.The Observatory is divided into three sections:A Dashboard that provides free data on the cost of capital for energy projects in emerging and developing economies, updated with 2023 and 2024 data in July and…

Financing the Modernisation of Power Systems Beyond Coal
The role of transition credits in Southeast Asia Coal is a central component of power systems in Southeast Asia, even as governments have committed to reducing coal‑related emissions. Rapid electricity demand growth, alongside coal’s role in system adequacy, reliability and energy security, complicates efforts to accelerate coal transitions. Recent volatility in international gas markets has reinforced the short‑term economic and security value of existing coal assets, adding complexity to national transition strategies. The region’s young coal fleet also implies substantial long‑term emissions if plants continue operating at current utilisation rates.Against this backdrop, new approaches are being explored…

Unlocking Ukraine’s Hydrogen Opportunity: A Roadmap
Ukraine’s energy sector has been severely affected by the Russian Federation’s full-scale invasion. The power sector went from having a large capacity surplus before the war to a power deficit in 2024 due to Russia’s attacks. This has focused attention on energy security and restoring the reliability of supply. Hydrogen demand from conventional applications in refining and ammonia has also plunged, falling 80%, with most of these assets in southern Ukraine, where the frontline and occupied areas are located. Overall economic damage from the war has been extensive, with reconstruction costs previously estimated by the World…

The Value of Demand Flexibility
Benefits beyond balancing This policy brief, developed under the International Energy Agency’s Digital Demand-Driven Electricity Networks (3DEN) Initiative, examines the value of demand flexibility as a core component of modern electricity systems, with a strong emphasis on its role in improving energy efficiency. As electricity demand grows and power systems become more electrified, decentralised and renewable-rich, managing when and how electricity is used is increasingly as important as expanding supply.The brief sets out a clear framework for understanding demand flexibility and highlights its contribution to an efficiency-first approach to power system planning and operation. By…

Financing the ASEAN Power Grid
The Association of Southeast Asian Nations (ASEAN) has a long history of electricity system connectivity, and the development of the ASEAN Power Grid (APG) is central to achieving a sustainable, secure and affordable energy transition across the region. Delivering the APG will require a significant step‑change in investment over the coming 15 years, and unlocking financing from a diverse range of sources will be essential for this to happen. Yet financing approaches and business models have not evolved at the pace required to support an increasingly ambitious and complex pipeline of interconnector projects.This report examines how interconnectors are approached…
