My little brother used to do electrical installations. He once set up a device that deactivated the power in a building as soon as no more consumers were on. Of course that thing is probably still using power continuously itself.
On that same note, shouldn't it be possible to install a mechanism that doesn't use any power at all? Something like, uh, I'm not gonna say a light switch, but a weightless switch, to mix a few metaphors here.
