Top 10 countries leading in Energy Transition Index 2025: Global progress towards secure, equitable, and sustainable energy systems has accelerated significantly, reversing years of slow advancement, according to the World Economic Forum (WEF).
In 2025, 65 per cent of countries improved their Energy Transition Index (ETI) scores, with 28 per cent advancing across all three core dimensions: security, sustainability, and equity.
Advanced economies continue to lead, occupying 16 of the top 20 spots in the ETI rankings.
Sweden, Finland, Denmark, Norway, and Switzerland topped the list, excelling in energy diversification, clean energy adoption, robust policies, and reliable infrastructure.
Notably, Latvia entered the ETI top 10 for the first time in 2025. Emerging Europe and Asia also made significant strides, driven by targeted reforms, enhanced infrastructure, and increased clean energy investments.
| Rank | Country | ETI 2025 Score | Change since 2016 (%) |
| 1 | Sweden | 77.5 | 9.7 |
| 2 | Finland | 71.8 | 2 |
| 3 | Denmark | 71.6 | -0.4 |
| 4 | Norway | 71.5 | 4.2 |
| 5 | Switzerland | 71 | 5.8 |

Methodology: The World Economic Forum (WEF) collaborated with Accenture to benchmark the performance of 118 countries’ energy systems across three dimensions (security, sustainability, and equity) and five readiness factors (political commitment, finance, innovation, infrastructure, and education/human capital).
Among the largest economies, China has achieved its best-ever position at 12th, driven by strong innovation and the highest clean energy acquisition volumes in the world.
The US ranks 17th due to its solid security measures and improvements in sustainability.
However, it has slipped down to its previous year’s position – 63rd in the 2024 Global Energy Transition Index but made notable strides in reducing CH4 emissions and boosting energy efficiency and clean energy investment capability this year.
To boost its ranking, it can improvement in grid reliability, rural energy access, and reduced reliance on imported energy could boost energy security and equity. Investment in infrastructure and renewable sources could also speed up this transition.
