Standby power — some people call it vampire load — is what equipment draws while it is not being used. Any one device is small. Added up across a house, it is not.
The usual suspects
- Cable boxes and streaming boxes: on many models standby and on draw nearly the same.
- Desktop computers and monitors: sleep still pulls a steady load.
- Older power adapters: if it is warm, it is drawing. Left plugged in after charging, that is pure waste.
- The second refrigerator in the garage: frequently the single largest item in the house, especially if it is old.
- Hot water recirculation pumps: worth checking whether yours runs constantly or on demand.
Finding yours
Guessing does not work. The direct route is circuit-level monitoring at the panel: look at what the baseline draw is at three in the morning and which circuits it sits on. That number is the floor of your house, and every saving starts from there.
If you are not ready for a full monitoring install, a plug-in meter tested device by device gets you there too. It just takes longer.
What to do about it
Once found, the fix is usually easy. Smart plugs on a schedule to cut power overnight; entertainment gear grouped onto one switchable circuit; the old refrigerator costed out for replacement — which pays back faster than people expect.
Do not switch everything
Leave the network gear, the recorder, the refrigerator and the thermostat out of any automatic cut. The small saving is not worth the system going offline at 2am.
