Some devices still use electrical power even when they are turned off.
If your cell phone charger is plugged it (even of the cell phone isn't), the transformer which is why the plug end is usually so large, still dissipates a very small amount of power.
Things like a DVR, TV, etc typically use a small amount of power even if they are turned off. If you would think about it, when you pick up your remote to turn your TV on, how is the TV going to even see the IR signal from your remote unless the IR circuit in your TV is powered all the time.
Your DVR has the capability of recording programs even when you turn it off,,, but there are substantial parts of that DVR which aren't really turned off.
Anything that has a small light on it even if it is off, but just plugged in, use a small amount of power.
Your computer may be set to power down when you aren't using it, but if you can go over and tap on the keyboard and then in a second or two, have the computer start up again, the computer isn't entirely off and it is using some power all the time.
Individually, the power of each one of these devices is quite small. If you think you will be able to unplug a couple things and see a change in your power bill, you are wrong.
Just to use a round figure, electricity typically costs in the area of 10 cents per kilowatt hour. It would not surprise me if it took 200 cell phone chargers to be plugged in to add up to a load of 1000 watts.
None of this is rocket science folks... I'm surprised that anyone even has to ask this sort of thing.
