Which valley are you going to drown? Hydro being pretty much at capacity...

• ncmncm 5y ago
  Hydro storage is a completely different animal than native hydro generation. A reservoir for the latter requires a river collecting water from a large area watershed, and a dam lower down backing water up the river course. Hydro storage requires only an elevated basin, and a pipe (penstock) leading up to it from a ready source of water -- even groundwater -- no watershed needed. Such basins are legion, and filling them typically discomfits no one.

    Given the capacity needed (TWhs), such basins are going to be massive, and will drown valleys.

      No valleys, no drownding.
