> In March, April and May 2026, both technologies independently surpassed nuclear generation. Global solar capacity increased by 510 GW to 2,383 GW, up 27% year on year, while wind added a record 159 GW to reach 1,291 GW, an increase of 14%. By comparison, installed nuclear capacity rose by just 1.5 GW to 399.5 GW, while operating nuclear capacity declined by 0.5 GW to 368.6 GW.
If global solar capacity was 1873 GW in 2025, global wind capacity was 1132 GW, and global nuclear capacity was 398 GW, how could solar and wind have surpassed nuclear in March of 2026 for the first time?
