Renewable energy capacity worldwide expanded by over 12% in 2025, driven primarily by wind and solar installations, according to the International Renewable Energy Agency (IRENA). This growth aligns with SDG 7: Affordable and Clean Energy, signaling strong global commitment to decarbonizing power sectors. Solar energy alone accounted for nearly half of the new capacity added last year, supported by falling technology costs and enhanced grid integration.
However, experts caution that investment gaps remain, especially in developing nations where energy access still lags. Energy storage and grid modernization are identified as critical enablers to fully harness renewable potential and stabilize energy supply.
Policy frameworks fostering innovation, financing, and equitable access will be essential to meet rising clean energy demands and keep global temperature rise below 1.5°C.
