Energy Efficiency 2024 is the IEA’s primary annual analysis on global energy efficiency developments, showing recent trends in energy intensity and demand, prices and policies. The report provides sector-specific analysis on buildings, appliances, industry and transport and explores system-wide themes such as electrification, flexibility, investment and employment. This report is launched in parallel with the new IEA Energy Efficiency Progress Tracker, which can be accessed directly through the IEA website.

The IEA’s flagship World Energy Outlook, published every year, is the most authoritative global source of energy analysis and projections. It identifies and explores the biggest trends in energy demand and supply, as well as what they mean for energy security, emissions and economic development.

Using energy more efficiently has proven to be an extremely successful and cost-effective way to reduce energy demand. Highly developed and well proven policy instruments already exist to deliver increased energy efficiency, such as Ecodesign in Europe and Japan’s Top Runner. These policy tools can also support fuel switching and better demand management, helping to integrate higher volumes of variable electricity supply.
