Between 2025 and 2030, the world is expected to build nearly 4,600 gigawatts of renewables — almost double the amount built over the previous five-year period.

If you thought the world built a lot of renewables in the past few years, just wait for the next half of this decade.
Between 2025 and 2030, the world is expected to build nearly 4,600 gigawatts — or 4.6 terawatts, if you please — of clean power, according to a new report from the International Energy Agency.
That’s nearly double the amount built over the previous five-year period, which was in turn more than double the amount built across the five years before that. Put differently, the growth has essentially been exponential.
Solar is the driving force behind this expansion, which is key to transitioning the world away from planet-warming fossil fuels.
Installations of onshore wind will leap from 505 GW over the previous five-year period to 732 GW between 2025 and 2030. Offshore wind will more than double from 60 GW to 140 GW.
