Multiple Benefits of Energy Efficiency for Business
Energy efficiency is often described as the “first fuel” because the cheapest and most secure energy is the energy that is not used. For businesses, this begins with a straightforward benefit: lower energy bills. In many cases, efficiency investments can pay back quickly through reduced energy costs alone. However, the value of energy efficiency extends beyond energy savings.This report builds on the IEA’s work on the multiple benefits of energy efficiency and focusses on how these gains materialise in businesses. Key benefits range from productivity and product quality improvements to brand image or health benefits for employees and…

Financing the ASEAN Power Grid
The Association of Southeast Asian Nations (ASEAN) has a long history of electricity system connectivity, and the development of the ASEAN Power Grid (APG) is central to achieving a sustainable, secure and affordable energy transition across the region. Delivering the APG will require a significant step‑change in investment over the coming 15 years, and unlocking financing from a diverse range of sources will be essential for this to happen. Yet financing approaches and business models have not evolved at the pace required to support an increasingly ambitious and complex pipeline of interconnector projects.This report examines how interconnectors are approached…

The Value of Demand Flexibility
Benefits beyond balancing This policy brief, developed under the International Energy Agency’s Digital Demand-Driven Electricity Networks (3DEN) Initiative, examines the value of demand flexibility as a core component of modern electricity systems, with a strong emphasis on its role in improving energy efficiency. As electricity demand grows and power systems become more electrified, decentralised and renewable-rich, managing when and how electricity is used is increasingly as important as expanding supply.The brief sets out a clear framework for understanding demand flexibility and highlights its contribution to an efficiency-first approach to power system planning and operation. By…

IEA Guide to Reporting Energy Technology RD&D Budgets
This manual, developed by the International Energy Agency (IEA), provides comprehensive guidance for national experts responsible for reporting energy technology research, development, and demonstration (RD&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…

Korea 2025
Energy Policy Review Government action plays a pivotal role in ensuring secure and sustainable energy transitions. Energy policy is critical not just for the energy sector but also for meeting environmental, economic and social goals. Governments need to respond to their country’s specific needs, adapt to regional contexts and help address global challenges. In this context, the International Energy Agency (IEA) conducts Energy Policy Reviews to support governments in developing more impactful energy and climate policies.This Energy Policy Review was prepared in partnership between the Government of Korea and the IEA. It draws on the IEA’s extensive…

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…

Best Practices and Insights to Expand Clean Energy Access and Adoption
This report was commissioned by the European Commission to serve as a technical repository of analysis and evidence-based practices in support of the Campaign on Sustainable Lifestyles, Fairness and Access to Clean Energy Technologies. The analysis presented draws on discussions and research shared during the Widening Participation in Clean Energy workshop held in Brussels, contributions presented at the official all-member meetings of the Campaign on Sustainable Lifestyles, and the IEA’s analytical work in areas such as people-centred clean energy transitions, affordability, energy efficiency and clean energy access.This work is organised into three chapters, each corresponding…

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…

Scaling Up Transition Finance
Scaling Up
Transition
Finance Actions by emissions-intensive sectors, companies and countries are crucial to placing the world on a sustainable pathway. Yet investments that could deliver meaningful reductions in their environmental footprint often do not receive sufficient financial support. Currently, finance is drawn heavily to certain “green” assets and activities. While vital, these investments alone cannot deliver all the changes needed to cut global emissions, especially in areas where clean technologies are not yet commercially available or cost-competitive. This is where transition finance comes in: it can help emissions-intensive countries, companies and sectors shift over time towards…

Multiple Benefits of Energy Efficiency
As energy efficiency continues to gain attention as a key resource for economic and social development across all economies, understanding its real value is increasingly important. The multiple benefits approach seeks to expand the perspective of energy efficiency beyond the traditional measure of energy savings by identifying and measuring its impacts in full bloom.
