You might want to get a little meter, so that you can figure out exactly what things are drawing. Look up Kill-A-Watt. It was an eye opener to me, to see what each device is actually drawing.
I measured the draw on my washer and dryer and found a significant 'phantom load', where they are still drawing energy when they aren't running. I need to put a switch on that circuit, so that I can shut that off while not using them. I was also shocked to find that my home entertainment center (tv, computer, amplifier) was using ~120kwh/ month. I've since ditched the amplifier and started powering down the computer to minimize that usage. I have a couple refridgerators, one draws 80kwh/month, while the newer one uses 50kwh/month, so I'm also planning to ditch the older fridge for something more efficient.
And I agree with GuitarStv, if I had electric heat and a natural gas fireplace, I would run the fireplace quite often.
Also, check the temperature that the water heater is set at, it doesn't really need to be above 140º, but read up on the tradeoffs.
