Super insightful article, thanks for walking us through. While I now understand how much energy the Bitcoin system required to keep running, I would love to have a similar energy consumption calculation for, let's say, the USD or the EUR, because it would be nothing but fair to compare apples with apples. For USD energy consumption we'd have to factor in all the office buildings, people and more engaged in sustaining that system. The energy bill wouldn't be low neither I suppose. I couldn't find any information on that online though.
