Well I dropped my idle consumption average over night from about 560w down to 510w, mostly from discovering that my work PC was set to never sleep or turn off the display (3 of them).
- My office dropped from 105 watts to 45
- The furnace accounts for about 150 watts idle consumption where it keeps temps above 65 degrees.
- The refrigerator accounts for about 75 watts of idle consumption.
- Bedroom is still idling at 40 watts- I need to find out why.
- Modem, router, server consumption is around 30 watts; just below the threshold for a branch circuit to detect
That all adds up to 330 watts, so I've got nearly 200 watts unaccounted for at this point. Time to switch off breakers and see what happens. This process of hunting down phantoms involves starting out with the big picture and slowly zeroing in on branch circuit consumption, and then individual energy consumers.
