It's no coincidence that bitcoin mines sprout up anywhere that is saturated with cheap, renewable energy. Most often around hydro plants where the cheap power can be used that would have just been wasted anyway. These extra funds make renewable power much more economical.<p>No one wants to mine anywhere that energy costs more than 5c per kwh, and basically any populated area where demand is present the prices are going to be somewhere between 10-20c per kwh.
