WEF Energy Transition Index 2026: Record $3.3T Investment but First Decline in Readiness in Over a Decade

Record Investment, Stalled Momentum

Global energy investment reached an all-time high of $3.3 trillion in 2025, of which approximately $2.3 trillion flowed into clean energy . Renewables and nuclear together generated 42% of global electricity, and renewable capacity increased by nearly 800 GW . Yet these gains face mounting constraints: grid congestion, permitting delays, trade restrictions, and conflict-based disruptions are preventing investment from translating into system-level progress . The transition readiness decline signals that the foundational conditions for sustained progress are weakening .

Top Performers: Nordics Lead Again

Sweden, Finland, and Denmark retained the top three positions globally, reflecting robust infrastructure, diversified low-carbon energy systems, and long-term policy stability . Advanced economies accounted for 14 of the top 20 rankings .

India: A Strong Improver Amid Global Headwinds

India advanced two places to rank 70th and was one of the strongest improvers globally, recording one of the largest gains in transition readiness . The improvement was driven by gains in energy access, efficiency, and clean energy deployment, even as the global backdrop deteriorated .

Saudi Arabia: Standout in the Middle East

Saudi Arabia was called the standout country in the MENA region, with its overall ETI score rising 1.5% to 57.4 . The improvement was backed by stronger financial backing, accelerated renewable deployment, and investments in large-scale battery storage . Saudi Arabia, alongside Israel and the UAE, continued to outperform the global average in the region .

Geopolitical Risks and Energy Security Decline

The report flags several critical risks:

• Energy security was the only dimension of system performance to decline (-0.9%), hit by weaker reliability and supply conditions .
• Geopolitical tensions and supply disruptions — including the closure of the Strait of Hormuz — are directly slowing progress .
• The equity dimension rebounded, sustainability held steady, but the overall momentum remains fragile .
• The Middle East and North Africa region saw an overall decline of 0.9%, as "weakening policy commitment and infrastructure investment weighed on progress" .

What Must Happen Next

The WEF calls for urgent action to rebuild the enabling environment, including: strengthening grid infrastructure, scaling battery storage, diversifying supply chains, and maintaining long-term policy stability to close the gap between record investment volumes and tangible transition outcomes .
