The Energy Transition Index 2026 tracks energy transition progress across 120 countries, measuring both how energy systems perform today and whether the conditions for future progress are in place.

After several years of slow momentum, energy transition progress has accelerated, according to the World Economic Forum's Fostering Effective Energy Transition 2025 report. The Energy Transition Index (ETI), which benchmarks 118 countries on their current energy system performance and on the readiness of their enabling environment, finds improvements in energy equity and sustainability driven by easing energy prices, subsidy reforms, lower energy and emission intensity and increased share of clean energy. However, energy security has made more limited progress, and transition readiness momentum has slowed. Meanwhile, global energy systems are facing increasing pressure from climate change, geopolitical, economic and technological disruptions.

The report finds that while energy efficiency and clean energy adoption have improved, the transition has slowed due to rising energy prices and geopolitical risks, with energy equity and security remaining major challenges.

The report highlights that while clean energy progress continues, the global energy transition has stalled due to the energy crisis and geopolitical instability, with emerging challenges in energy equity and security.

The report focuses on balancing energy security, affordability, and sustainability amid recent crises, highlighting the urgent need for climate action and decarbonization.

The report highlights 10 years of progress in renewables and energy access, while stressing urgent action to address challenges in affordability, security, and inequality.

The report highlights COVID-19's disruption to the energy transition, stressing the need for collective action and strengthening energy systems to ensure a secure, sustainable, and inclusive future.

The report benchmarks countries on energy performance and readiness, emphasizing the need to accelerate the transition across economic, security, and sustainability dimensions.

The report introduces the Energy Transition Index (ETI) to benchmark 114 countries on energy access, affordability, and sustainability, stressing the need for cross-sector collaboration.

The report highlights ongoing challenges in the energy sector, including shifts in prices, production, and geopolitical instability, while revisiting key trends in economic growth, sustainability, and energy security.
