That implies your electricity usage is ~2.4 kWh/day. How do you get the low?
In the US, an idling desktop computer, an energy efficient refrigerator, and a fan for household air circulation would be enough to exceed that.
I just download usage details from my electric company for a bill from the middle of summer when my usage is lowest, which provides usage broken down by 15-minute intervals, and the lowest 15-minute interval I had was using electricity at a rate of 4.8 kWh/day.
(The highest was a rate of 193 kWh/day. Probably had a 15-minute interval where the water heater was on, at the same time as the electric clothes dryer, while I was cooking something using the electric oven/stove, and microwaving something, while the well pump was running, and the iMac was doing something CPU intensive, while the fridge happened to be running).
