We discussed that before, and concluded that the current banking/financial system still uses much more Energy and other resources than Crypto (just calculate the amount of AC's in bank buildings around the world...).
Nevertheless: the race in the Miners world is to build the most energy-economic Chips (even at 7 nm). And studies are done to change the POW into POS algorithms (Ethereum is the first to try stepping over, if they prove it gives the same Security as POW than Bitcoin might follow).
You are comparing the infrastructure of fiat currencies with just the mining energy costs of bitcoin. There are infrastructure costs for bitcoin. I.e., a place like Coinbase certainly eats its fair share of energy. The currency itself shouldn't be consuming energy in order to operate.
