bitcoin mining does not need grid power, just internet connection. you can set up a mine in the middle of the desert, or in antarctica, and it works just fine. if grid energy gets expensive enough, a lot of things will become unfeasible but bitcoin won't be one of them.

You still have to have a ton of power. You won't generate all that outside of a power grid unless you own your own hydro dams or something.
