| Yes. This article gives an estimate of about 2% of all electricity usage going to bitcoin mining. All data centers in the country combine to a similar ballpark in energy usage (another comment states 1-3%). Finance accounts for 20% of US GDP, so we'll be charitable, round up its usage of datacenters to 50%, to get about 1% of electricity from financial data centers. There are about 6.7 million employees in the financial sector [1]. Assume everyone has a computer with a 600W power supply at full bore for 12 hours a day [2]. That comes out to about 18 billion kWh of electricity a year, which is (checks math) 0.425% of US electricity consumption [3]. Sure, I'm not accounting for all the PoS systems at every retail location in the country, but they're going to use far less energy than even the overspecced numbers I'm using. So overall, this comes out to about 1.5-2% of US electricity usage going to the financial sector, less than Bitcoin mining. Also remember that magically switching everything over to Bitcoin would still require all those PoS systems, not to mention large fractions of Wall Street and bank branches and whatnot, so this isn't really a fair comparison overall. And some amount of the financial sector includes cryptocurrency companies already.
