Global Energy and Climate Model
…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 and Climate Model (GEC Model) is now the principal tool used to generate detailed sector-by-sector and region-by-region long-term scenarios across IEA publications, including the World Energy Outlook series and Energy Technology Perspectives series.Download the GEC Model Methodology document for an in-depth description of the overall approach and features of the model, and download the GEC Model Key Input dataset for selected key input data.

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…

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.

Electricity 2026
…such as artificial intelligence (AI), data centres, and evolving technological innovations.Against this backdrop, Electricity 2026 – the IEA’s annual report on global electricity systems and markets – provides in-depth analysis of the recent trends and policy developments underpinning this new era. It includes forecasts for electricity demand, supply and carbon dioxide (CO2) emissions for select countries, by region and worldwide. This year the forecast period has been expanded to five years, 2026-2030, compared with the previous three-year outlook.As electricity use grows, power systems will need greater flexibility to securely and cost-effectively integrate an increasingly diverse…

Multiple Benefits of Energy Efficiency for Business
Energy efficiency is often described as the “first fuel” because the cheapest and most secure energy is the energy that is not used. For businesses, this begins with a straightforward benefit: lower energy bills. In many cases, efficiency investments can pay back quickly through reduced energy costs alone. However, the value of energy efficiency extends beyond energy savings.This report builds on the IEA’s work on the multiple benefits of energy efficiency and focusses on how these gains materialise in businesses. Key benefits range from productivity and product quality improvements to brand image or health benefits for employees and…

Global Energy Review 2025
…covering data for all fuels and technologies, all regions and major countries, and energy-related carbon dioxide (CO2) emissions. The latest data show that the world’s appetite for energy rose at a faster-than-average pace in 2024, resulting in higher demand for all energy sources, including oil, natural gas, coal, renewables and nuclear power. This growth was led by the power sector, with demand for electricity rising almost twice as fast as wider energy demand due to higher demand for cooling, rising consumption by industry, the electrification of transport and the growth of data centres and artificial intelligence…

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…

Gas Market Report, Q2-2026
…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 20% of global liquefied natural gas (LNG) supply due to the effective closure of the strait is distorting short-term gas market fundamentals, while damage from attacks on LNG liquefaction facilities in the Middle East is altering the medium-term outlook. The conflict is now expected to delay a significant amount of new LNG capacity that had been on track…

Energy and AI in East Asia
…Korea Energy Economics Institute and was carried out jointly by the International Energy Agency (IEA) and the Korea Energy Economics Institute. The study has three objectives in the context of East Asia. First is to explore the possibilities presented by AI for the energy sector. Second is to examine the expected increase in electricity demand by data centres, and the impact on grid planning and operation. Third is to provide policy recommendations for embracing the opportunities presented by the application of AI to energy, as well as policies for proactively managing the challenges presented by the consumption of energy by AI…

Coal 2025
…thirds of global coal use today is for power generation. On the other, the rapid expansion of renewable energy capacity – particularly in China, the world’s biggest coal consumer – has the potential to curb demand. At the same time, the coming wave of liquefied natural gas (LNG) export capacity, which is likely to bring more abundant supplies and lower prices to natural gas markets, could prompt some regions to favour gas over coal.Coal 2025 – the latest annual market report from the International Energy Agency (IEA) – explores the implications of these key developments and more. Drawing on the latest data…
