Just yesterday I noticed that a device installed by the cable TV company in my house (a WISI VX 2030 amplifier, according to the sticker) was warm to the touch. Measuring its power consumption, it uses a constant 15 watt, so about 130kwh/year.

I don't use cable.

Cable Modems are notorious energy hogs. I'm pretty sure some of the ones I've seen run their CPU at 100% all of the time in busywait loops. They are always warm to the touch.

Did you turn it off?

Yes, I unplugged it.
