Renewables in District Energy
…around 600 million people worldwide, but many systems remain heavily dependent on fossil fuels, exposing consumers and utilities to price volatility, supply risks and high emissions.The report provides a global overview of district energy systems, their fuel mixes, market conditions, governance models and affordability implications. It explores the growing opportunities offered by renewable and recovered heat sources, including bioenergy, geothermal, solar thermal, waste heat, large-scale heat pumps and thermal energy storage. It also sets out policy priorities for three types of markets: established systems with high renewable shares, fossil fuel-intensive networks, and emerging or untapped district energy markets.

Global Methane Tracker 2026
…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 most recent data from satellites and measurement campaigns – and discusses different abatement options along with their associated costs. This year's…

Financing the ASEAN Power Grid
…how these assets are financed in practice and what must change to make them bankable for a wide set of potential investors.By quantifying total investment needs and potential sources of finance, identifying key barriers and offering clear, actionable recommendations, this report aims to equip policy makers, regulators, utilities, financiers and private‑sector stakeholders with the guidance needed to accelerate the financing and implementation of the ASEAN Power Grid. This analysis has been supported by the Clean Energy Transitions Programme, the IEA’s flagship initiative to transform the world’s energy system to achieve a secure and sustainable future for all.

Financing the Modernisation of Power Systems Beyond Coal
…emissions from operating plants, and considers the investment and power system planning challenges of replacing coal generation while maintaining essential system services. It also reviews project‑based and emerging jurisdictional approaches to transition credits, focusing on methodologies for the early retirement of grid‑connected coal plants and their replacement with clean energy.By examining these issues from a power system, investment and carbon markets perspective, the report aims to provide a clearer understanding of coal transition strategies and outlines recommendations for countries that may choose to explore transition credits as an option to reduce the role of coal in their electricity mix.

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 Efficiency in China’s Buildings Sector
…progress in achieving them. Regulation for new buildings in China, such as building codes, is relatively strong. However, as the rate of construction is slowing, policy priorities are shifting towards retrofitting existing buildings. Here, the IEA estimates that through strong policy action and best-in-class technology, China could reduce energy consumption by up to 65% in buildings constructed between 1995 and 2010, representing energy savings of over 8 000 Petajoules.The report includes examples from across China and the world on leading regulatory instruments, financial incentives, and information-based tools that can drive energy efficiency in the buildings sector.

Chile 2050 Energy Transition Roadmap
…with the Chilean Ministry of Energy, sets out a detailed pathway for the country to reach its legally binding goal of net zero emissions by 2050 while expanding economic growth and improving energy security and affordability. This pathway relies on four pillars: accelerating energy efficiency, decarbonising the power sector, electrifying end-use sectors, and building modern, resilient electricity grids. The report examines the investment needed to realise the pathway, the opportunities to reduce household bills, and the improvement of air quality. It explores how Chile can also leverage its natural resources in the global energy transition with opportunities for the…

Demand- and Supply-Side Measures for the Industry Transition
Policy brief As governments look to scale up lead markets for near-zero and low-emissions steel and cement, targeted policy measures can help overcome commercialisation barriers, capture emerging market opportunities and support broader government objectives. This policy brief explores a variety of possible policy instruments to stimulate demand and supply of such industrial materials, providing options that governments could adopt and adapt as part of their industrial policy framework – tailored to their unique circumstances to enhance effectiveness – along with practical next steps towards implementation.
