We have electric heat, but never use the heater from the HVAC system.
Eddie,
Make certain this is the case. In the winter of 2006/2007 we made the mistake of setting our hvac to "E Heat". We thought "E" mean efficiency when it actually meant "Emergency". Our light bill had double during that period.

Our 2975 sq ft house with unfinished basement was built 3 yrs ago to R-2000 specs, test rated 92% efficient. We average 24.6kWh per day for 2009. 2008 was 24.9 kWh/day. We pay $0.10 per kWh so that works out to about $75 a month. 2 adults, no kids.
Factors that reflect our bill:
- Main face of house faces west on a hillside, windy location. So the solar factor really helps...also fades the hardwood floors and furniture too.
- House is heated with a air course heat pump which doubles as a/c in summer. It will draw heat from the air down to about -20C (-4F) before the electric heat kicks in. Apparently some thinks there's still heat in the air at -20 C

- We run a wood stove in the winter, located in the living room, center of the house, 17ft ceilings.Currently burn about 6 full cords a year. Installed a ceiling fan last year...made a HUGE difference in the comfort level. Prior to the wood stove we were burning about 35 kWh a day.
All the appliances you may have, while small, do add up. But its not like you can unplug your fridge at night.

I know that a computer plugged in 24/7/365 cab add as much as $75 or more to an annual bill. All those batter y charges, cell phone charges that remain plugged in while not connected to a cellphone or filled with batteries all consume. The little things add up but I'd bee looking for the big ticket items first.
High wattage light bulbs. Thermostat active with windows left open while heat or a/c is running. Hot water tank that is too small for the occupancy of the home. Dirty filters in your heating system or hvac. If your basement is unfinished and the rim board is uninsulated, you can lose up to 5% of your home's energy that way. Improper ceiling insulation or improper installation.
The last house we had, we increased the attic insulation to R40 from R15 (1970's house) and we saved $50 a month in heating bill.
Its either that or your neighbor has tapped into your feed because he's running a grow-op
