Then PHS is around 9.5 Megawatthours per year?
Enough to be proud, data of POWs in same scale would be interesting, maybe this energy can be made out of trees  


Compare 1.6 Terrawatthours (math) or double >3.2 TWh (experience), i dont know many physical processes near that, seems close to a nuclear powerplant or developing country. Satoshi took electricity like gold, a rare resource, was he aware of upcoming years too? Large amounts of energy produced clean, cheap and everywhere by solar, fusion or whatever. Numbers given by science drawing a scenery where competition on energy is less relevant, and so POW can be. Hard to predict timescales or truth, what always stays relevant is a functional planet of course.
