We as supporters of bitcoin already know that it's totally a false allegation over bitcoin that it consumed the highest electrical energy for mining operations.Critics just want to target bitcoin by any means.Also even if it consumed higher energy,its not related to coal and mostly hydro electric power.
Such accusations are really trying to undermine Bitcoins reputation. Many of my friends have asked me if these accusations are true. Luckily I could tell them again and again that such statements about Bitcoin are not true. Printing and producing fiat money consumes more electricity worldwide than Bitcoin. The process alone of melting down metals and thus minting coins consumes a large amount of electricity. People don't think about that. So I can refute the statement that Bitcoin is a power guzzler.
