Re: Our PG&E Bill averages $600-$800 per month, sometimes more.. Someone around here was complaining about high electric bills. He eventually traced it to a built-in space heater that was running 24/7 in an unused bathroom in the basement. See - »Re: WTF Massive, unexpected jump in Electricity usage... :(
You might want to turn off everything in your home (at the individual devices, not the breakers), then see if your meter is registering any usage. Go from there, and track down any other power draws.
EDIT: Compared to the average usage shown in your graph, you're using an extra 850 kWh per month. Guess what - That's the equivalent of a 1200 Watt space heater running 24/7. Hmmm...
