A bit more complex, but it doesn't have to be more expensive...

I think this is massively overblown, it was actually hard to manage a grid with baseload generation, since you still needed peaker plants for the morning and afternoon peaks and then had massive amounts of excess power overnight.

It's just that that's what people were used to, not that it's actually the best or easiest model for managing grids.

Highly variable sources bring some different challenges than the old status quo, but we also have much more sophisticated technology in the power space now anyway. And that new and sophisticated tech can produce new opportunities that outweigh the challenges if anything.

So I take arguments like yours with a massive grain of salt. How you put it is not really the case.
