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.

    Turned up all the way and running 24/7 even on hot days.

    I bought Bitmain's Antminer L3+ because its AP3++ power supply can operate with Truly American 110 volts. The Anminer S9 and Bitmain's other miners all require 220v.

    A common friend connected me with someone who's building a mining rig colocation facility in what used to be a weed gro-op. When Colorado legalized The Devil's Plant gro-ops sprouted like mushrooms but many of them closed down because of competition - but fortunately for me an the proprietor of that facility, the gro-ops installed lots of extra electricity before they went tits up.
