Energy and AI in East Asia
…the 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…

IEA Guide to Reporting Energy Technology RD&D Budgets
…D) budgets. It outlines the methodology and classification system used to collect and structure RD&D data across IEA member countries, ensuring consistency and comparability. The manual is divided into two main sections: fundamentals of RD&D budget reporting and a detailed classification of energy technologies. It defines RD&D in alignment with the OECD Frascati Manual and clarifies the scope of public and private sector reporting. It also provides instructions for completing the IEA questionnaire, covering budgetary stages, metadata reporting, and common issues. The classification system spans nine major technology groups, including energy end uses, fossil fuels, renewables, nuclear…

Policy options to accelerate distributed solar PV in Ukraine
…energy storage deployment will support Ukraine in establishing energy security.In the year following the Russian Federation’s full-scale invasion of Ukraine in 2022, available dispatchable power generation capacity halved from roughly 38 GW to 19 GW. After severe attacks in spring 2024, capacity declined further, down to 12 GW. Towards the end of 2024 Ukraine was able to restore 3 GW and has worked to restore and add additional capacity throughout 2025, despite ongoing attacks.Distributed solar PV has played a key role, providing cost effective and rapid increases in electricity generation capacity, contributing to system resilience and overall energy…

China’s Official Energy Finance in Emerging and Developing Economies
…linked to uneven availability of concessional or long-tenor finance.This report maps and analyses these changes through an energy sector-level dataset covering 2015 to 2024. It explores how China’s evolving financing model is reshaping instruments, institutions and regional allocation patterns, and also considers the strategic and practical implications for EMDE energy transitions.The analysis is complemented by case studies covering a range of technologies and financial structures – from large-scale renewables and electricity distribution to green industrial projects, waste-to-energy and upstream developments – which show how China’s official actors operate in practice across contrasting markets…

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…

Renewables in District Energy
…can play a larger role in district energy systems, helping to deliver cleaner, more secure and more efficient heating and cooling. District energy networks already supply heat to 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…
