as of nov, 2018:

estimate - bitcoin mining accounts for about 1 percent of the world's energy consumption.

As of 2018, the computers on the bitcoin network were doing 342,934,450 gigahashes per second.
Mining companies that run lots of ASIC miners as businesses claim they use one watt of power for every gigahash per second of computing performed when mining for bitcoins.

At this rate, the bitcoin network runs at 342,934,450 watts—roughly 343 megawatts. Calculations based on EIA data reveal that the average U.S. household consumes about 1.2 kilowatts of power, meaning that 343 megawatts would be enough to power 285,833 U.S. homes.
