sorrros, thanks for clearing, all our calculations as on reddit came to the same result, 1.6 Terrawatthours per year. >1 J per GH/s may more reality, think on old mining hardware, mining bots, badly configured software, free/cheap energy some use on their workplaces, etc. Other carbon wasting systems like cars can be fixed, mining is competitive by design, sorry BTC and many alts, your energy consumption looks broken.

Just for understanding, Antminers data on power consumption should be 590 Ws, not Watt as they wrote?
