According to a press release carried by Eurekalert
In the first rigorously peer-reviewed article quantifying Bitcoin's energy requirements, a Commentary appearing May 16 in the journal Joule, financial economist and blockchain specialist Alex de Vries uses a new methodology to pinpoint where Bitcoin's electric energy consumption is headed and how soon it might get there.
The abstract of the article says
The Bitcoin network can be estimated to consume at least 2.55 gigawatts of electricity currently, and potentially 7.67 gigawatts in the future, making it comparable with countries such as Ireland (3.1 gigawatts) and Austria (8.2 gigawatts). [...]
The author offers a caveat:
[...] all of the methods discussed assume rational agents. There may be various reasons for an agent to mine even when this isn't profitable, and in some cases costs may not play a role at all when machines and/or electricity are stolen or abused.
[Other] reasons for an agent to mine Bitcoin at a loss might include [...] being able to obtain Bitcoin completely anonymously, libertarian ideology [...] or speculative reasons.

I myself only go to the ATM when otherwise I would be totally screwed.
There's always two tellers at my credit union, sometimes three. They're all really happy to see me because quite likely I'm the only live human to set foot in their branch all day.
This despite their free coffee in plain view from outside their door.
While I use Amazon to read reviews, I buy local to the extent I possibly can. And if I really do have to order online, despite reading amazon's reviews I make my actual purchases at some other site.
