2025 saw total renewable power capacity reach 5,149GW after the addition of 692 GW, or a 15.5 per cent of annual increase, according to new report by the International Renewable Energy Agency (IRENA).

The Renewable Capacity Statistics 2026 also finds renewable energy dominates the total capacity expansion at 85.6 per cent share, while non-renewables continue to account for a smaller share of additions.

Commenting on the findings, IRENA director-general, Francesco La Camera said, “In the midst of uncertain time, renewable energy remains consistent and steadfast in its expansion. This not only indicates market preference but also makes a strong case for renewable energy resilience with brutal clarity. A more decentralised energy system, with a growing share of renewables and more market players, is structurally more resilient. Countries that invested in the energy transition are weathering this crisis with less economic damage, as they boost energy security, resilience and competitiveness.”

In line with the previous year, solar energy led the increase, accounting for 511GW or approximately 75 per cent share in the total renewable capacity addition. Wind energy followed suit, adding 159GW. Together, solar and wind accounted for 96.8 per cent of all net renewable additions last year, reflecting the biggest cost decrease among all renewable technologies. Bioenergy took the third place with 2.3 per cent annual growth, adding 3.4GW to total renewable energy expansion.
