Integrating Distributed Energy Resources in China
…international experience Like no other country in the world, the People’s Republic of China (hereafter, “China”) is witnessing rapid growth in distributed energy resources (DERs), including rooftop solar photovoltaics, battery storage and electric vehicle (EV) chargers. As China advances towards its carbon peaking and neutrality goals, these resources offer a unique opportunity to support a more flexible, efficient and resilient power system, provided their integration is well-managed.This report analyses recent trends in DER deployment across China and highlights the emerging challenges their growth poses for power system planning and operation, calling for renewed attention to distribution grids…

Unlocking Ukraine’s Hydrogen Opportunity: A Roadmap
…industrial base that can help to restore the fiscal balance. This is a long-term opportunity that will not happen overnight, but efforts need to start today to progressively build the experience required to enable such an industry in the future.The report identifies the actions required across four pillars (physical assets, regulation, financing and cross-cutting areas) and three time horizons (covering from 2 to 20 years), in order to provide a roadmap to enable the renewable hydrogen opportunity. Policy recommendations Explore what actions can be taken in the short term to lay the foundations for future hydrogen deployment.

China’s Official Energy Finance in Emerging and Developing Economies
Evolving institutions, instruments and implications for clean energy transitions Global energy investment exceeded USD 3.3 trillion in 2025, but capital flows remain uneven. Emerging market and developing economies (EMDE) outside China attracted just 27% of total energy investment and 18% of clean energy spending, despite accounting for nearly two-thirds of the global population and the bulk of future demand. Addressing this imbalance requires mobilising more capital from diverse sources into EMDE energy systems.China continues to play a central role in global energy investment flows because of its large domestic investments and its large external capital spending on energy. Since…

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.

Policy options to accelerate distributed solar PV in Ukraine
Accelerating distributed solar PV and battery 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…

Energy System Resilience
…Agency (IEA) has worked closely with Ukraine, an 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…

Ukraine’s Energy Security
A pre-winter assessment As Ukraine enters its fourth winter of war, ensuring that residents retain reliable access to heat and power is of the utmost importance. While Ukraine made strong strides in rebuilding and strengthening the resilience of its energy system this past spring and summer, the situation remains fragile, and the risk of huge disruptions and widespread destabilisation remains – particularly as Russia expands the scope and sophistication of its attacks.This analysis builds on the IEA’s September 2024 report, Ukraine’s Energy Security and the Coming Winter. It provides an update on the latest developments through October…
