Renewable power made up almost 50% of the world’s electricity capacity in 2025, according to data from the International Renewable Energy Agency (IRENA). This growth was driven by a record increase in solar installations, with a total of 511 GW rising to 2,392 GW. The share of renewables in global electricity capacity rose to 49.4%, up from 46.3% the previous year. Over 100 countries agreed to triple renewable energy capacity by 2030 as part of efforts to meet global climate targets. The IRENA has yet to publish its full-year data for 2025.
