An average household uses 18.1 KW hours per day [0].
So we have:
18,100 [Watts * hours/day] / 24 [hours/day]
= 754 Watts.
So yeah, I got it wrong. My bad for not doing the units sanity check on
the calculation.
Another useful comparison is to the world's electricity consumption,
which was 20,181 TW hours / annum in 2008 [1] (which is approx 20 PW
hours, peta watt hours, peta = 10^15).
20e15 [Watts * hours/year] / (366 [days/year] * 24 [hours/day])
= 20e15 [Watts * hours/year] / 8784 [hours/year]
= 2.8e12 Watts.
So bitcoins usage the worlds electricity consumption is:
38e6 Watts * 100 [%] / 2.8e12
= 0.0013%
