Re: Energy "storage" via existing hydro
This does not work outside special cases -- Norway being one such of course! There's not enough hydroelectric capacity worldwide and there essentially can't be enough because there aren't enough suitable places to put huge volumes of water high up which are reasonably near other places much lower down, short of civil engineering on an implausible scale.
Note I'm emphatically not against hydroelectric power (or any other kind of renewable power), or against this technique being used when it can be used, such as in Norway.
