Renewable energy sources now make up nearly half of all power generation infrastructure worldwide. According to the authors of the newly released report, sustainable energy sources reached a significant milestone by accounting for 49% of the world’s total installed electricity capacity by the end of 2025.
Supporting this finding, the report states that “By the end of 2025, renewables accounted for 49% of global installed power capacity, and comprised 85.6% of annual global power additions, largely due to significant growth in solar and wind power.”
In practical terms, this means that for every 100 megawatts of power plant capacity available to generate electricity across the globe, nearly 49 megawatts are now provided by green technologies like wind turbines and solar panels. This shift is being driven by an overwhelming preference for new green projects, which represented over 85% of all new power-generating equipment connected to the world’s grids during the last year.
The report “Renewable Capacity Statistics 2026” was published by the International Renewable Energy Agency (IRENA) in Abu Dhabi. Released in 2026, the comprehensive statistical review was prepared by a dedicated team of authors including Julian Prime, Iman Abdulkadir Ahmed, and Dennis Akande. It provides a detailed global accounting of green energy deployment and capacity trends through the end of 2025.
