After that first TW, it’s expected that the world (mostly China) will add a TW of capacity every year, starting 2026. Staggering speed of growth if it actually comes to fruition! For comparison, the world currently has a total of about 7 TW of installed capacity!

Note that capacity does not mean actual power generated, but this is still huge.
