Problem is you don't end up storing much energy IIRC.
There are places where "spare" energy is used to pump water up hill into a
hydro scheme IIRC .... but I think that's the hydro scheme itself. No
obvious reason why wind can't be used for the same purpose.

think that They were Us. If it was Them, then nothing was anyone´s fault.
If it was Us, what did that make Me ? After all, I´m one of Us. I must be.
I´ve certainly never thought of myself as one of Them. No-one ever thinks
of themselves as one of Them. We´re always one of Us. It´s Them that do
the bad things. <=> Terry Pratchett. Jingo.
