    The article talks about the coming droughts and water shortages. Pumped hydro is nice, if you have water.

      There’s evaporation, which can be mitigated by floating solar panels, but pumped hydro is a closed system, it doesn’t consume water.

      You save the water in a hole, then pump it back and forth. You can cover it with PV to stop evaporation

      This is also good for the droughts as you have emergency water.
