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…

Integrating Distributed Energy Resources in China
Lessons from international experience Like no other country in the world, the People’s Republic of China (hereafter, “China”) is witnessing rapid growth in distributed energy resources (DERs), including rooftop solar photovoltaics, battery storage and electric vehicle (EV) chargers. As China advances towards its carbon peaking and neutrality goals, these resources offer a unique opportunity to support a more flexible, efficient and resilient power system, provided their integration is well-managed.This report analyses recent trends in DER deployment across China and highlights the emerging challenges their growth poses for power system planning and operation, calling for renewed attention to…

Demand and Supply Measures for the Steel and Cement Transition
The case for international co-ordination A massive scale-up of markets for transformative near-zero emissions steel and cement is needed to achieve internationally agreed net zero goals. Yet early movers on both the supply- and demand-side – that is, material producers and consumers – face substantial barriers related to high costs and risks, among other factors. This has led to relatively slow market growth for near-zero emissions materials, at a moment when reinvesting in long-lived high-emissions production could have repercussions for governments to achieve their stated climate goals. Policy makers have the opportunity to play a…

Electricity Market Design
Building on strengths, addressing gaps Electricity markets play a central role in balancing supply and demand, guiding operational decisions and shaping investment outcomes. As systems change with higher shares of variable generation, greater decentralisation and evolving patterns of electricity use, the ability of market designs to deliver secure and affordable electricity has never been more critical. If market arrangements do not keep pace with these developments, the functioning of electricity systems could become more uncertain and more costly.This report provides a cross-regional assessment of how wholesale electricity markets and their complementary policy mechanisms are performing today. We find…

Gaining an Edge
The Role of Energy Efficiency in Enhancing Competitiveness Energy efficiency delivers more than energy savings and emission reductions – it can also improve the competitiveness of countries and firms. From increased profitability to job creation, energy efficiency helps firms compete amid high costs, growing demand, and rising trade pressures. In today’s global context, energy efficiency is not only a matter of energy policy, but also of economic policy.The report analyses historical progress in industrial energy efficiency and its role in enhancing industrial competitiveness. It includes comparisons of firm-level energy efficiency, identifying performance gaps and opportunities for further improvement. Drawing…

World Energy Outlook 2025
The IEA’s flagship World Energy Outlook (WEO) is the most authoritative source of global energy analysis and projections. Updated annually to reflect the latest energy data, technology and market trends, and government policies, it explores a range of possible energy futures and their implications for energy security, access and emissions. The WEO covers the whole energy system, using a scenario-based approach to highlight the central choices, consequences and contingencies that lie ahead. It includes exploratory scenarios that flow from different assumptions about existing policies, as well as normative pathways that achieve energy and emissions goals in full. The multi…

Global Hydrogen Review 2025
Global Hydrogen Review 2025 The Global Hydrogen Review is an annual publication by the International Energy Agency that tracks hydrogen production and demand worldwide, shedding light on the latest developments on policy, infrastructure, trade, investments and innovation. The report is an output of the Clean Energy Ministerial Hydrogen Initiative and is intended to provide an update to energy sector stakeholders on the status and future prospects of hydrogen, and to inform discussions at the Hydrogen Energy Ministerial Meeting organised by Japan.The sector has progressed significantly since the first publication of the Global Hydrogen Review in 2021. Low-emissions hydrogen…

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…

World Energy Employment 2025
The World Energy Employment (WEE) report series provides comprehensive tracking and analysis of the global energy workforce, including estimates of its size and distribution across regions, sectors, and technologies. It also assesses how energy labour requirements evolve to 2035 across all IEA scenarios.The WEE 2025 – the fourth edition – examines how skilled labour needs and shortages have changed since the series first highlighted these issues in 2022, and explores their implications for education and training systems, wages, policy, and the global buildout of energy infrastructure. This year’s report introduces, for the first time, detailed occupation-level estimates that offer…

Health
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores health. Why is energy efficiency important for health? Energy efficiency can improve health by creating healthy indoor and outdoor living environments with comfortable temperatures and humidity levels, and improved air quality. Key facts Energy efficiency measures have been linked to improved health, such as fewer respiratory illnesses.Targeted energy efficiency programmes can reduce doctor and hospital visits and save health costs. In New Zealand, a retrofit programme led to a 43% reduction in hospital admissions for respiratory conditions, while a similar programme in Ireland reduced the…
