Household Energy Affordability: Data and Indicators
A methodological framework for national monitoring Effective policy requires robust monitoring of household energy affordability, yet no unified methodological approach currently exists. The upcoming IEA report Household Energy Affordability: Data and Indicators, to be published in July, addresses this gap. This executive summary presents its key elements, including a robust methodological framework structured around dimensions, indicators and data to support policy discussions and national monitoring efforts.

Vehicle-to-grid technology
…bidirectional charging, EV owners can reduce charging costs and, in some cases, generate revenue by participating in grid services, such as frequency regulation. Load shifting and vehicle‑to‑grid (V2G) capabilities provide substantial electricity system benefits, helping reduce peak demand and potentially limiting the need for future grid investment – benefits for which EV owners can be compensated. Vehicle-to-grid charging holds the promise of alleviating grid constraints but barriers remain The rollout of EVs is a major driver of global electricity demand growth. Residential EV charging can draw more power than any other single household load, including heating, cooling, lighting and…

Clean Energy Transitions Programme 2025
Annual report 2025 The IEA’s Clean Energy Transitions Programme (CETP) helps countries around the world accelerate their transition to clean energy, with a focus on emerging markets and developing economies. By combining global analysis, high-level convening and hands-on technical support, the CETP ensures that evidence, policy guidance and practical tools reach those shaping energy strategies on the ground.In 2025, the CETP has supported almost 350 high-level bilateral meetings with policy makers, over 700 workshops and technical exchanges, involving almost 13 000 participants, and 26 capacity-building events with over 1 700 policy professionals on energy efficiency, data…

Heat Pump Taxonomy
A common framework for heat pumps classification and data Heat pumps are a cornerstone technology for achieving secure, affordable and sustainable heating. They have become one of the most common heating technologies and have the potential to impact significantly future trends for energy consumption in buildings and beyond.Tracking and analysing the pace of heat pump deployment compared to that of conventional heating technologies is essential for understanding future needs with regards to energy demand, investments in electricity infrastructure and fuel supply.Despite their growing importance, data on heat pump installations, as well as on their performance and cost, remain…

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.

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.

Scaling Up Demand Flexibility
…initiative to examine the growing importance of demand flexibility in electricity systems amid rising demand, increased renewable energy integration and the electrification of power systems. Case studies in chronological order to examine the changing role of demand flexibility over time from South Africa (2025), Thailand (2030) and Ireland (2035) demonstrate how demand flexibility improves reliability, reduces costs, supports renewables integration and manages network constraints. To realise these benefits, the report emphasises the role for smart technologies, inclusive policies, regulatory reforms and consumer engagement to scale flexibility and move away from emergency interventions, towards a more strategic and efficient system capability.
