The World Economic Forum (WEF), in partnership with consulting firm Accenture, has released its 2025 Energy Transition Index (ETI), which assesses the energy performance of 118 countries based on 43 indicators grouped under three pillars: energy security, environmental sustainability, and equity in energy access.
The ETI also evaluates countries’ readiness for energy transition using five key factors: regulation and political commitment, financing and investment, innovation, infrastructure, and human capital.
Each country is scored from 0 to 100 per indicator, with an overall score combining current energy system performance (60%) and transition readiness (40%).
Tunisia 2nd top performer in Africa
Tunisia performed well in this year’s edition, scoring 54.6, placing 2nd in Africa and 62nd globally.
Nigeria edged slightly ahead with a score of 54.8, ranking 61st worldwide. Nigeria’s rise, up 48 places from 2024, is attributed to targeted regulatory reforms, increased investment in clean energy, and transition strategies tailored to local conditions.
Following Tunisia in Africa are Namibia (64th globally), Mauritius (69th), Morocco (70th), Egypt (74th), South Africa (79th), Kenya (88th), and Algeria (89th). Côte d’Ivoire rounds out the African top 10 at 90th globally.
Sweden global leader in energy transition
Sweden leads globally, followed by Finland, Denmark, and Norway, all scoring above 70, thanks to strong political will, resilient infrastructure, and low-carbon energy systems. Switzerland, Austria, Latvia, the Netherlands, Germany, and Portugal complete the global top 10.
The report notes a renewed momentum in the global energy transition: 65% of assessed countries improved their scores in 2025, with nearly a third showing gains in all three dimensions: security, sustainability, and equity.
