You generate more heat bending over to unplug it and plug it back in that IT generates being left in all the time. And actually there is a little surge that happens when you plug in the charger which is harder on the circuit than leaving it plugged in all the time.
A nightlight uses 5 to 7 watts of power which is more than the iPad uses while running. Stop using the 1000 watt microwave oven if you want to save some energy. A fraction of a watt in the charger is Not what the power companies are complaining about, it's the inductive loads of the little transformers from the cheap cordless phones and old cell Phone chargers and little power tools that are making non-unity power factor loads on the grid that waste energy. I didn't want to get technical but there, it's said!
