Affordability
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores affordability. Why is energy efficiency important for affordability? Energy efficiency measures can reduce energy bills for households, decrease energy poverty, and make access to energy services more affordable. Key facts Energy efficiency measures can reduce average household energy bills in advanced economies by up to one-third. In emerging economies, they can also improve access to energy services. For many products, such as refrigerators, highly efficient models use less than half of the energy of inefficient models. A best-in-class model can save up to…

Nickel
Outlook for key energy transition minerals This report provides an outlook for demand and supply for key energy minerals including copper, lithium, nickel, cobalt, graphite and rare earth elements. Demand projections encompass both key energy technologies and other uses under different IEA Scenarios. Supply projections are based on a detailed review of all announced projects. They show how today's geographical concentration evolves over time, for both mining and refining and how expected supply compares with primary supply requirements.

Prospects for Natural Gas Certification
…from North America. As certification continues to evolve, opportunities remain to improve consistency, transparency and coverage across the full supply chain. To support further progress, the report outlines potential policy actions for governments to consider –such as international collaboration on harmonisation, setting minimum standards for certification, and exploring ways in which certification could complement emerging regulatory and market frameworks.While not a standalone solution, certification can enhance transparency and performance on GHG emissions across natural gas supply chains. This can support broader efforts to reduce emissions and strengthen energy security by improving accountability and easing comparability across different supply chains.

Global Methane Tracker 2026
Around the world, many countries have made reductions in methane emissions a policy priority as part of their efforts to limit near-term global warming, enhance energy security, and improve air quality. The energy sector – including oil, natural gas, coal and bioenergy – accounts for around 40% of methane emissions from human activity and has some of the best opportunities to cut these emissions. The annually updated Global Methane Tracker provides essential data on methane emissions across the energy sector and the opportunities to bring them down.The Tracker presents the IEA’s latest sector-wide emissions estimates – based on the…

Oil 2025
Analysis and forecast to 2030 Global oil markets have so far had a turbulent 2025. Heightened trade tensions and uncertainty have weighed on the world economy and, by extension, oil demand growth. Combined with the recent OPEC+ decision to accelerate the unwinding of oil production curbs that have been in place for several years, these factors have recently pushed international oil prices to four-year low in April and early May. At the same time, shifts in energy policies are affecting oil producers and consumers alike, with oil supply security remaining high on the international energy policy agenda.Oil 2025…

Global Methane Tracker 2025
Methane is responsible for around 30% of the rise in global temperatures since the Industrial Revolution, and rapid and sustained reductions in methane emissions are key to limiting near-term global warming and improving air quality. The energy sector – including oil, natural gas, coal and bioenergy – accounts for more than 35% of methane emissions from human activity and has some of the best opportunities to cut these emissions. The annually updated Global Methane Tracker is an essential tool for raising awareness about methane emissions across the energy sector and the opportunities to bring them down.The Tracker presents our latest…

Energy System Resilience
…Association country, on energy system resilience, publishing a 10-point plan ahead of the 2024-2025 winter, along with a 2025-2026 update and a roadmap for decentralising Ukraine's power system. This has provided Ukraine with critical assistance, while also offering invaluable real-world lessons that can inform resilience planning for IEA Member countries and beyond. Industry from Europe and other regions is already collaborating with the Ukrainian private sector and learning from practices forged under extreme conditions as they provide support. This report distils key lessons from Ukraine's experience that can inform energy system resilience efforts worldwide.

Energy savings
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores energy savings. Why is energy efficiency important for energy savings? Energy efficiency measures reduce the amount of energy required to fuel and grow our economies. In economies where energy demand is set to grow significantly, efficiency also helps improve people’s lives by increasing access to additional energy services. Key facts In the last two decades, efficiency measures have generated over 27 EJ of energy savings in IEA countries alone, equivalent to 20% of total energy demand.The industry (including manufacturing) and services (including commercial buildings) sectors…

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…
