'Just'? Are you crazy. The flood tide comes twice a day - billions of
tonnes of water in almost constant movement. Stand next to Menai bridge
one day and take a guess at the wasted megawatts. 400 feet down, the
earth's crust is close to boiling point in many areas, and will be for
the next million years. The sun shines every day in the Sahara. How
much more energy do you want?

Eneergy can be stored very, very easily, without digging holes in
mountains. You can use it to electrolyse water into hydrogen (and lots
of handy oxygen) or engage it in any number of reversible physical or
chemical activities.
Better still, you can grow crops which fix carbon, then burn them to
release it again.
I don't want to be rude, but you really know bugger all about
renewable, sustainable energy. Are you in the oil industry?
