Just find an abandoned dam and build a hydro system there, power your miners and a cell phone to the internet, then go :-)
No dam needed:

Basically,a horizontal water wheel,create a vortex of running water to spin the wheel

How a whirling wheel is "fish friendly" am not sure

Have to be pretty deep under the wheel..........
