Other payment methods use electricity as well. It is just that it is not as transparent as to how much electricity visa for example uses to process their payments. Visa must power their office buildings, computers for employees, computers that process transactions, banks that send money to/from visa (their employees, offices, and computers), printers that print customer statements, call centers to resolve disputes.
