I have to say that I don't unplug things at all at night.
If you take a typical Satellite Receiver, ours spends 30% of it's life in Standby mode.
24 Hours X 365 Days = 8760 hours
30% standby time of 8760 hours = 2628 Hours
Power usage in Standby mode = 3 watts per hour at a cost of 18.61c per Unit.
Which means it will costs me 66 cent a month to leave it plugged in.
lol... for the sake of not having to plug in 365 times and out 365 times a year, I'll gladly pay the 66 cent a month.
Regards.
James.
