Rising geopolitical tensions, supply chain disruptions and surging energy demand are fragmenting the global energy transition and slowing progress toward cleaner, more secure energy systems, according to the World Economic Forum’s (WEF) Energy Transition Index 2026, released in collaboration with Accenture.
The report says that despite record global energy investment of $3.3 trillion in 2025, including $2.3 trillion in clean energy, progress has stalled as energy security concerns, infrastructure bottlenecks and financing challenges continue to hinder the transition.
WEF noted that recent disruptions in the Strait of Hormuz have further exposed the vulnerability of global energy systems, particularly for import-dependent emerging economies, highlighting the need for more resilient and diversified energy supplies.
According to the index, overall energy transition performance remained largely unchanged over the past year, with declines in energy security and transition readiness offsetting gains in sustainability.
While around 60% of countries improved their overall scores, only one in four achieved balanced progress across energy security, sustainability and equity.
