There seem to be many frivolous uses of power to complain about when you get to this level of power use.
GIMPS' ~1PetaFLOPS[1] uses no more than a megawatt [2].
That's about 10 Gigawatt-hours (GWh) over a year [3].
The average US house uses about 10 MWh in a year [4] so GIMPS = the electrical power use of ~1,000 households. Portland reduced their power consumption by 20 GWh by switching their street lights to LEDs[5].
The electrical consumption for Superbowl parties is an estimated 75 GWh [6]. (I think Superbowl parties are far more frivolous.)
