Yeah, and even poorer to mid rich countries (that have hydro potential) can rely on it, locally, with no need to import solar panels, for example. Albania, for example, is 100% renewable, and has been for decades, thanks to hydro.
Sucks you can't build hydro everywhere. I kinda wanna see more "run of the river" type of hydro. I think there's more potential for that, and it's less damaging to the surroundings. It's intermittent tho. I'd love to see it locally in my region, I think it could work.
