I have certain lights on timers so the are on automatically (so I don't have to stumble into a dark room) and they are off automatically, so they aren't forgotten and left going all night. Most of us are creatures of habit enough to do this with a few well placed lamps. I cannot over state how useful this is.
On some power company sites it's estimated that these few things can save as much as 10% off an electric bill! And here in FL I go even farther during the bad storms and unplug everything I value. I know it sounds drastic, but there is no other way to insure important electrical items are safe from the super spikes we get here in the lightening capital! I know there are other high-tech, expensive ways to protect these things, but I say the easiest and cheapest is best - so just unplug it during a storm and turn off the surge protectors and UPS outlets when not in use.
