IEA: Solar PV accounted for more than three-quarters of new renewable capacity in 2025

According to the International Energy Agency's Global Energy Review 2026, global renewable capacity additions increased by 16% in 2025, reaching 800 GW. It was the 23rd consecutive year in which renewables set a new expansion record.

The information below is summarized from the cited source.

The IEA says solar PV accounted for more than three-quarters of new renewable capacity additions worldwide in 2025, followed by wind at around 20%. The remaining share came from hydropower, bioenergy, geothermal, concentrating solar power and marine energy.

For solar PV specifically, annual capacity additions rose by around 12% and exceeded 600 GW for the first time. The IEA also notes that 30 countries installed more than 1 GW of solar PV in a single year, almost twice as many as in 2020.
