Re:Bitcoin’s energy usage is huge – we can't afford to ignor... by King-Aaron on Wednesday January 17, 2018 @08:18PM (#16173798)
It depends on how far you want to go.

The cost per transaction would be interesting in real terms.

What's the comparison between:

- Manufacturing physical currency / Manufacturing the hardware to mine coins - Cost to run POS systems in retail outlets / Cost to run bitcoin network - Cost to run global fiat exchanges (i.e. wallstreet) / Cost to run global bitcoin network

Obviously you could drill down as far as you wanted. I'd imagine it would be quite difficult to draw up such a detailed comparison though.
