Comment by naming_the_user

My first instinct was to say that this isn't much, but actually, it's not insignificant.

Say there's a billion users.

14975GWh implies then that each user has used 14975Wh or 15kWh. Per year.

Fairly spicy I think. It's about the equivalent of a full charge of a laptop once per two days, so it's at least as much as many (most?) end users would consume "by themselves".
