Comparing the amount of energy used for a bitcoin transaction to running home in the Netherlands: "This number needs some context. 200kWh is enough to run over 200 washing cycles. In fact, it's enough to run my entire home over four weeks, which consumes about 45 kWh per week costing €39 of electricity (at current Dutch consumer prices)."
Not only does Bitcoin use a vast amount of electricity to complete transactions, it uses an almost exponentially larger amount than more traditional forms of electronic payment.
"Bitcoin's energy costs stand in stark contrast to payment systems that have the luxury of working with trusted counterparties. E.g. Visa takes about 0.01kWh (10Wh) per transaction which is 20000 times less energy,"
