Global renewable power capacity was projected to more than double by 2030, led by rapid growth in solar PV, according to the IEA’s Renewables 2025 report. The sector faced supply chain, grid and financing challenges but continued expanding. Solar PV was expected to account for about 80% of new additions, followed by wind, hydro, bioenergy and geothermal. Growth was strongest in China, India, Europe and emerging markets in Asia, the Middle East and Africa. Offshore wind had a weaker outlook due to policy and cost issues. The forecast was slightly lower than last year because of regulatory shifts in China and the United States. Despite risks from concentrated supply chains in China, rising grid pressures and policy constraints, renewables remained the lowest-cost power source globally.
