Renewable energy is simply not sustainable.

Hydro electric power _is_ sustainable. You can keep catching the rain
and making power from it indefinitely.

What it _isn't_ is a solution for all our power needs - there just isn't
enough rain falling in enough mountain valleys.

AIUI wind/hydro works quite well in New Zealand, where they have lots of
wind and rain in a hilly country with low population density.

There is of course the Banqiao problem. Orders of magnitude more deaths
than have ever ben caused by nuclear power.
