Hm, how much energy DOES it take (how would I compare? not sure) to produce equivalent number of dollars? Is there maintenance cost? Interesting line of thought to me.
Most dollars are virtual, so the energy cost is just sending some small messages around. It’s orders of magnitude less than needed for a bitcoin transaction.
Physical currency probably takes more energy, but printing is an old and cheap technology, so I doubt it’s comparable.
