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…

Unlocking Ukraine’s Hydrogen Opportunity: A Roadmap
Ukraine’s energy sector has been severely affected by the Russian Federation’s full-scale invasion. The power sector went from having a large capacity surplus before the war to a power deficit in 2024 due to Russia’s attacks. This has focused attention on energy security and restoring the reliability of supply. Hydrogen demand from conventional applications in refining and ammonia has also plunged, falling 80%, with most of these assets in southern Ukraine, where the frontline and occupied areas are located. Overall economic damage from the war has been extensive, with reconstruction costs previously estimated by the World…

Energy security
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores energy security. Why is energy efficiency important for energy security? Energy efficiency can help mitigate energy security risks by reducing the reliance on fossil fuel imports, improving grid reliability, and acting as a buffer to supply shocks. Key facts Efficiency gains from the last two decades avoided the need for 20% more fossil fuel imports in IEA countries. Energy efficiency and demand response can support grid reliability by reducing peak demand. For instance, more efficient air conditioners in India could lower the impact of heatwaves on…

Energy and AI
Energy and AI The development and uptake of artificial intelligence (AI) has accelerated in recent years – elevating the question of what widespread deployment of the technology will mean for the energy sector. There is no AI without energy – specifically electricity for data centres. At the same time, AI could transform how the energy industry operates if it is adopted at scale. However, until now, policy makers and other stakeholders have often lacked the tools to analyse both sides of this issue due to a lack of comprehensive data. This report from the International Energy Agency (IEA) aims to fill this…

Emission reductions
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores emission reductions. Why is energy efficiency important for emission reductions? Energy efficiency can reduce emissions of greenhouse gases and air pollutants and make the energy system more sustainable. Key facts Since 2010, efficiency measures avoided energy-related carbon dioxide (CO₂) emissions equivalent to nearly 20% of the global total in 2023. This is more than the entire energy-related emissions of India and the European Union combined. Accelerating efficiency improvements could deliver a third of all energy-related CO₂ emission reductions between now and 2030 in…

Sheltering From Oil Shocks
Measures to reduce impacts on households and businesses The conflict in the Middle East has created the largest supply disruption in the history of the global oil market, due to the near halt in shipping traffic through the Strait of Hormuz. The loss of supply is having significant impacts in global markets, pushing up prices for crude oil above $100/barrel, and leading to much higher prices for some refined products – notably diesel, jet fuel and liquefied petroleum gas (LPG). Concerns are growing about the impacts of higher prices on households, businesses and the broader economy.In this report, the…
