The world just added a record amount of wind and solar in 2025, and it’s not even close.

New data from global energy think tank Ember shows that 814 gigawatts (GW) of new solar and wind capacity came online last year, up 17% from 2024’s 696 GW. That brings total global wind and solar capacity to 4,174 GW – or just over 4 terawatts.

That’s a massive buildout of the two fastest-growing sources of electricity in history, and solar is doing most of the heavy lifting.
