There was an article[0] which estimated that the entire global banking system (down to lamps on desks in offices) used 100Twh a year, whereas Bitcoin used around 30Twh a year (for a relatively insignificant volume of transactions). I don't know how accurate that is, but despite the unfavourable statistics, the article was still from some pro-Bitcoin person concluding that we should "stop complaining about Bitcoin and start complaining about Xmas lights". Also note that Bitcoin's energy use has since risen to 110Twh a year[1].
