All the "little" power consumers we have in our houses can really add up. All those wall wart power supplies hidden behind desks - some forgotten and connected to nothing - some connected to devices we seldom if ever use (my electric pencil sharpener comes to mind), alarm clocks, any device with a remote control, microwaves with clocks, your gas range with a clock in it, my bread machine even has a digital clock, cell phone chargers, cordless phones, caller ID boxes, sleeping computers, external hard drives, your modem and router, the battery charger for your digital camera, printers ... each of these draws a small amount of power 24/7. That can add up to more than some high current using devices that are only operated for a relatively short time each day.
I'd bet if many of us took the time to make a power audit of our homes we could find a bunch of devices we could unplug without sacrificing much.
