I have heard high level statistics and headlines around

blockchain uses more energy than the Netherlands

I am interested to compare this quantitatively to other utilities, for example email and social media.

How much energy does all the world's emails use?

Another way to think of this: how much energy would be saved if everyone immediately stopped sending emails, and they didn't use any substitute for emails?

  • $\begingroup$ @PeteW energy from HD Video consumption would probably be a more interesting question! Next time.. $\endgroup$ – stevec Mar 28 at 13:19
