Energy and Emissions per Value Added Database
Sectoral value-added data and energy efficiency indicators for all OECD and 100 non-OECD countries Value added data is the basis for analysing how economies are structured, and to develop sectoral energy intensity indicators – useful to monitor trends in the economic efficiency of various activities, as a complement to data based on physical indicators.The IEA has developed the current database to provide the most complete coverage of sectoral value-added data, at current and constant prices, and associated energy efficiency indicators. This database merges value added data from three databases (OECD and UNSD National accounts, and OECD Trade…

Thematic session: New frontiers in modern and efficient data centres
Event backgroundIn today’s context of energy market volatility and economic uncertainty, energy efficiency remains essential for affordability, energy security, and competitiveness. The 11th Annual Global Conference on Energy Efficiency will bring together global leaders to accelerate action, with data centres emerging as a key focus due to their rapidly growing electricity demand.Data centres are critical infrastructure for digital and energy transitions, but their electricity use is rising quickly. The IEA estimates their electricity consumption was nearly 500 terawatt hours (TWh), or about 1.5% of global electricity consumption in 2025, and will double by 2030. Ensuring efficient and…
