In the last decade or so hydro generation has grown about as much as solar and wind (they all basically grow about the same amount as global nuclear generation, hydro doubling and wind and solar growing exponentially from basically zero).

So it's not going to take off like solar but it's a big chunk of relatively clean electricity production and it's often basically a byproduct of managing water supplies. It also pairs really well with renewables as even without pumps it has a degree of flex and storage.
