Comment on Bitcoin estimated to use 0.5% of the world's electric energy by end of 2018parent

As opposed to the utter waste of multiple resources and everything included in the pipeline between dollar issued and dollar spent?

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.
