I also read somewhere that the majority of the bitcoin "engine" was located close to renewable power sources that did not otherwise have good markets to sell their power. Whether that's actually true or not, the possibility that bitcoin could find the low cost renewable sweet spots throughout the worlds power grid and make use of them is interesting and helps to address the efficiency criticism. I think I'm still overall anti-bitcoin but I am questioning my assumptions.
