Just UNPLUG IT!
Common sense tells us to shut things off when they are not being used. Although a lamp may be turned off, if it is plugged in, it is still emitting unused energy. If you have certain items in your apartment that you don’t use on a daily basis, unplug them. If you’re going on vacation, unplug them. On a side note, there are a few companies that have introduced eco-friendly power strips that allow you to kill idle electric currents.
