Energy savings
…increased activity, such as home building and increased home sizes. In the transport sector, most efficiency improvements were realised in passenger vehicles – around one-sixth of the total. These energy savings were higher than the increased demand due to the rising number, frequency and distance of people travelling. Efficiency improvements in freight transport, such as trucks, drove around 1% of the total energy savings. This was lower than the rise in freight transport activity over the same period.

IEA Support to Accelerating Renewable Energy Permitting (ARPE)
Between October 2023 and March 2025, the IEA implemented the “Accelerating Renewable Energy Permitting” (ARPE) action. The goal of ARPE was to support five EU Member states – Finland, Ireland, Lithuania, the Netherlands, and the Slovak Republic (Focus countries) – in developing and implementing policy and regulatory measures aimed at reaching their renewable energy targets, notably through accelerating permitting of renewable energy projects.In support of this objective, the IEA organised and facilitated five workshops focused on the following topics:streamlining administrative proceduresaccelerating offshore wind deploymentfacilitating spatial planning for renewable energy deploymentensuring public engagement and acceptance, and afinal workshop summarizing the project…

Battery Circularity
…into the key issues for battery technologies, the report presents the very latest data as a guide to decision makers from the public and private sectors. It sheds light on the main locations of patenting, the leading patentors in the world and the technology categories receiving the most innovation attention.More than one in four cars sold globally in 2025 was an electric vehicle, reliant on lithium-ion or other modern batteries. But around 1.2 million electric vehicle batteries could reach the end of their lives in 2030 and 14 million in 2040, and today’s supply chains for…

Integrating Solar and Wind in Southeast Asia
Status and outlook for secure and efficient strategies Southeast Asia is experiencing one of the fastest electricity demand growths globally, with consumption set to double by 2050. While renewable deployment has accelerated in recent years, the region’s growing reliance on imported fossil-fuels for electricity generation, exposes countries to volatile fuel prices, potential supply disruptions and rising emissions. At the same time, the region possesses vast and diverse renewable resource potential. Variable renewable energy (VRE) - solar and wind - are now among the most cost-competitive generation options and are playing an increasingly important role in the region’s power…

Stepping Up the Value Chain in Africa
Minerals, materials and manufacturing This report explores key opportunities for African countries to step up the value chain in the growing global market for energy technologies, identifying opportunities beyond a role centred around extraction and mining to one more focused on mineral beneficiation, material production and technology manufacturing. These opportunities would enable Africa to retain a greater share of the economic value generated across energy technology supply chains, and would simultaneously contribute to global efforts to enhance supply chain diversification and resilience.The economic benefits of the new energy economy are currently distributed very unevenly. Emerging markets and developing economies…

State of Energy Policy 2026
…to the period 1973-2025, from oil and natural gas to clean energy technology supply chains and critical minerals. It also spotlights the policy momentum around energy access, most particularly in sub-Saharan Africa, taking stock of the policy progress since the IEA Summit on Clean Cooking in Africa in 2024.The State of Energy Policy series draw on the Global Energy Policies Hub, which tracks more than 6 500 measures across 84 countries and more than 200 policy types, and the Climate Pledges Explorer, exploring last climate commitments made for more than 190 countries, both updated with the release of the report.

India Bioenergy Market Report
Outlook for liquid and gaseous biofuels to 2030 As demand for renewable energy grows in India, liquid and gaseous biofuels are expected to be one of the fastest-growing markets, driven by significant feedstock potential and supportive policies. These fuels can provide low-emission energy in heat, electricity and transport. They can also be produced domestically reducing reliance on imported fossil fuels, improve energy security, and create economic development and employment opportunities.This report examines the current supply and demand of liquid and gaseous biofuels in India and their forecasted growth to 2030. It provides a detailed assessment of existing…

Renewables in District Energy
This report examines how renewables 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…

Southeast Asia Energy Outlook 2026
The Southeast Asia Energy Outlook 2026 is the seventh edition of this World Energy Outlook Special Report, making Southeast Asia by far the most regularly updated regional outlook compiled by the International Energy Agency (IEA). This reflects the dynamism of the region, as well as the importance of the IEA’s partnership with the eleven countries that make up the Association of Southeast Asian Nations (ASEAN) – Brunei Darussalam, Cambodia, Indonesia, Lao People’s Democratic Republic (Lao PDR), Malaysia, Myanmar, the Philippines, Singapore, Thailand, Timor-Leste (joined ASEAN in 2025) and Viet Nam.As energy security concerns move ever higher on…

Energy Efficiency in China’s Buildings Sector
…in industry and overall economic structural shifts. The buildings sector accounts for approximately 20% of its total final energy consumption and its intensity has decreased at a slower rate. There remains significant potential to unlock further energy savings through technical and policy initiatives in buildings.This report outlines opportunities for actions, targets and timelines that could improve energy efficiency in China's buildings sector. It includes an analysis of the country’s current buildings energy efficiency policies and the data that tracks progress in achieving them. Regulation for new buildings in China, such as building codes, is relatively strong. However…
