China’s Official Energy Finance in Emerging and Developing Economies
…linked to uneven availability of concessional or long-tenor finance.This report maps and analyses these changes through an energy sector-level dataset covering 2015 to 2024. It explores how China’s evolving financing model is reshaping instruments, institutions and regional allocation patterns, and also considers the strategic and practical implications for EMDE energy transitions.The analysis is complemented by case studies covering a range of technologies and financial structures – from large-scale renewables and electricity distribution to green industrial projects, waste-to-energy and upstream developments – which show how China’s official actors operate in practice across contrasting markets…

The State of Energy Innovation 2025
…milestones. It identifies areas where new approaches to policy support are being developed to use public funds more effectively, but also highlights areas where more efforts are needed to address barriers to scale-up and attract private capital. The report includes focus chapters on three dynamic fields, namely diversification of battery mineral supplies, application of artificial intelligence to energy innovation, and development of carbon dioxide removal technologies. The analysis provides a data-driven foundation to inform policy makers, industry and other stakeholders on the state of energy innovation worldwide and the importance of sustaining innovation momentum over the long term.

Gaining an Edge
…creation, energy efficiency helps firms compete amid high costs, growing demand, and rising trade pressures. In today’s global context, energy efficiency is not only a matter of energy policy, but also of economic policy.The report analyses historical progress in industrial energy efficiency and its role in enhancing industrial competitiveness. It includes comparisons of firm-level energy efficiency, identifying performance gaps and opportunities for further improvement. Drawing on a new IEA survey of 1 000 firms across 14 countries, it provides insights into industry perspectives. The report also highlights emerging opportunities in energy efficiency markets and offers recommendations for policymakers…

Grid investments
…nuclear. Key analysis IEA analysis of nine major regions shows that increasing electricity generation and grid capacity by one terawatt-hour (TWh), will require investments of USD 30 to 110 million in emerging economies and USD 75 to 150 million in advanced economies. In order to save the same amount of electricity, energy efficiency measures would cost only between USD 10 million and 50 million. A closer look at grid management The deployment of energy efficiency measures typically requires less time than the implementation of most new generation and grid infrastructure. On average, new generation and grid infrastructure can take years to implement, whereas efficiency measures…

…shown to lead to improved product quality and consistency, contributing to brand reputation.Improved resource use, such as reduced equipment downtime and unplanned shutdowns, lower maintenance costs, and potentially reduced staff requirements for operation and monitoring. Efficiency has also been shown to increase worker health and safety, reducing the incidence of work-related accidents and health insurance costs.Reduced waste production, such as less use of materials and process water.Combined, these multiple benefits can more than double the benefits of energy cost savings.
