WEF Energy Transition Index 2026: $2.3 trillion in clean energy investment faces geopolitical headwinds
Summary
The World Economic Forum's Energy Transition Index 2026, developed with Accenture, tracks energy systems across 120 countries using 44 indicators. Global clean energy investment reached $2.3 trillion in 2025, but these gains face mounting constraints. The early 2026 disruption to energy flows through the Strait of Hormuz highlighted vulnerabilities, sending oil and gas prices higher and forcing import-dependent economies into difficult trade-offs between energy access, affordability, and transition investment. Energy leaders reflect on where the energy system is changing and what it will take to get the transition back on track.
