Solar’s 2025 growth is the largest ever recorded for any energy source
Solar power just had its biggest year ever, adding 600 terawatt-hours to the global energy supply in 2025 — more than a quarter of all energy growth worldwide and the largest single-year jump any electricity technology has ever recorded. Battery storage quietly hit its own milestone too, with 110 gigawatts added in a single year, outpacing the best year natural gas has ever had. Meanwhile, electric vehicle sales topped 20 million, already nudging down global road fuel demand. Together, renewables and nuclear met nearly 60% of new energy demand. The takeaway is hopeful but honest: clean energy is finally outpacing fossil fuels in the places that matter most, even as the work of decarbonizing shipping, aviation, and heavy industry still lies ahead.
