Some large electronics can use as much energy as a light bulb while in "stanby" mode, meaning you should unplug them when you leave the house or know you won’t use them for awhile. Having a large electronic setup plugged into a power strip makes it much easier to completely power it down, especially if it has a lot of plugs like a home theater system or computer.
There are two situations which do not require you to be heating your home: when it is warm and when you are not at home.
