Energy Technology Perspectives 2026
…demand-side dynamics for energy technologies — such as deployment trends and policy developments — as well as supply-side factors, including manufacturing capacity and trade flows, underpinned by robust modelling and quantitative analysis. This year’s edition puts a special focus on vulnerabilities in energy technology supply chains and industrial competitiveness, analysing manufacturing cost structures and industrial policy impacts. The IEA’s Energy Technology Perspectives (ETP) series serves as the world’s guidebook for clean energy technologies. As the IEA’s flagship technology publication, ETP has been a key source of insights on all matters relating to energy technology since 2006…

Clean Energy Transitions Programme 2024
Annual report 2024 The Clean Energy Transitions Programme (CETP) is the International Energy Agency’s flagship initiative for accelerating clean energy transitions worldwide. Since its inception in 2017, the CETP has played a vital role in tackling the diverse challenges of energy transitions across the globe, fostering partnerships and providing tailored, actionable solutions. The programme is structured around three key pillars: directly supporting national transitions; strengthening multilateral co‑ordination; and delivering global analysis to inform policy dialogue.With significant milestones achieved in 2024, the CETP has supported over 320 high‑level meetings with policy makers, conducted 735 workshops and technical exchanges with…

Clean Energy Technology Supply Chain Data
…an essential role to play. The availability of good-quality, timely data is crucial to gaining this understanding and to identifying and addressing supply chain vulnerabilities.This report is provided as an input to the discussions taking place as part of the Global Clean Power Alliance Supply Chains Mission – an initiative established by the Government of the United Kingdom to advance practical solutions to strengthen clean power supply chains. This report addresses the data component of this initiative and explores the challenges – and potential solutions – to the paucity of granular and timely data associated with clean energy technology supply chains.

Manufacturing and Trade Model
…and Trade (MaT) Model was first developed for the 2024 edition of Energy Technology Perspectives (ETP) to produce scenario projections of manufacturing and trade across six key energy technology supply chains. These cover solar photovoltaics (PV), wind turbines, electric cars, batteries, electrolysers and heat pumps. This model is now used to generate detailed sector-by-sector and region-by-region long-term scenarios in IEA publications such as the World Energy Outlook and Global EV Outlook.The MaT model is part of the IEA’s broader modelling framework and is closely linked to the Global Energy and Climate Model (GEC)…

Energy Efficiency Policy Toolkit
…Canada. It aims to support governments in designing and implementing effective energy efficiency measures by combining policies across three core pillars: regulation, information and incentives. It also features a wide range of case studies, offering practical insights into the successful implementation of energy efficiency policies across diverse national and sectoral contexts.The Toolkit builds on earlier IEA work to advance energy efficiency policy. In 2022, the IEA introduced Policy Packages for Energy Efficiency to help governments deploy coordinated policy approaches across these three pillars. The Energy Efficiency Policy Toolkit was subsequently developed to also integrate concrete, sector-specific guidance, along…

Best Practices and Insights to Expand Clean Energy Access and Adoption
…follow low-emissions practices and are resilient and inclusive. It draws on international evidence, including workshop discussions, IEA analysis and a wide range of global case studies, to identify key impacts and lessons learned from evidence and practice. It highlights how behaviour change is most effective when supported by coherent policy frameworks, targeted measures addressing affordability and structural changes across sectors such as buildings, transport and appliances. By identifying good practices and practical insights, the report provides guidance to support policymakers design inclusive strategies that enable sustainable lifestyles and ensure the benefits of the energy transition are shared by all.
