What do you mean? Over the course of a decade and a half we brought the share of nuclear generation to 20%. That's way more impressive than what intermittent sources have achieved.
Persistently near-exponential growth over multiple decades isn’t impressive to you? If this carries on, peak PV output alone will exceed 100% of current total power demand by 2030.
(Naturally this means I think the growth seen since 1992 won’t last until 2030, but the point remains)
Assuming that exponential growth will be steady is a very risky assumption. Where's my single-core 100 GHz CPU? Moore's law says we should have that by now.
