Like any hydroelectrics it has large environment impact and dam failures tend to be the deadliest industrial disasters when they happen. Also most good locations have already been used. You cannot just build it wherever (without insane costs). Pumped hydro is hardly a solution here.

    Pumped hydro isn't the same as a hydroelectric dam. Because both reservoirs are engineered and you don't have the concrete wall as the single point of failure, you don't have the same risks involved. Pump Hydro can be whatever size you want and spread out to distribute the grid load.

    Also, are dam failures worse then Climate Change or are they just more dramatic?

    Then you either have small cheap and safe, without much capacity (so you need many of those), or big, with the problems of the big hydroelectric projects.

    Of course pumped hydro has and will have its place in the grid, but it cannot solve all the energy storage problems.
