Power generation
Someone told me the other day that many office blocks leave their lights on deliberately, under instruction from the power providers.
With the peak/offpeak power consumption differences I believe there are problems dealing with a sudden massive change in power demand (5:30pm, computers off, lights off, for huge skyscrapers?).
I'm not sure how true this is, but it makes a sort of perverted sense.
