There are a lot of variables not mentioned but -
As with most energy posts I highly, highly, highly suggest you have a home energy audit performed by a HERs certified evaluator. Be sure the auditor uses a blow door tester and a thermal camera. Use an auditor that is independent and not associated with an HVAC or insulation contractor. Your utility should have a list of locals or you can poke around a bit on the net and find one.
You can contact your local utility company regarding this. Many utes subsidize or pay fully for this work.

The cost of a professional one should be in the $250 to $400 range. Sounds like a lot but our utility pays all but $50 of it. If they are able to save you $200 per year by making a few adjustments it is well worth even the $400 investment. Hint -- They will save you money.
Here is an online audit tool that can help as well --
http://energysavings.togetherwesave.com/add-up-your-savingsSince I don't know if you heat or not with electric it is hard to advise. If you heat with it your not that out of line and perhaps need some adjustments. If that is just random power and AC then you are way high?
In general ---
Buy or rent or borrow (library) a Killawatt tester and put it to work.
Turn you water heater down to low and wrap it with R13 Batt. 1 - 8 ft section is all you need at about 10 bucks. Tape it up. Electric water heaters typically use $40 per month.
If your fridge is old, it is probably inefficient.
Dryers suck the heck out of electric. Cut usage (read tips on this site) to 1 load per person per week.
LEDs are great!
Read this site for tips on reducing AC usage, as in do you really ever need too?
But really, really, really have a professional audit done. The blow door tester alone will identify over 3 sq ft of leaks that can be plugged and caulked.
The heat camera will tell you if insulation is a culprit.
They will also give you a cost analysis to determine if it is worthwhile to buy new units, install heat pumps etc..
If you do install a heat pump check with your state for tax credits, the feds usually have these as well and your auditor should know all your current rules. Our utility for example has tons of rebates etc. for fridges, HVAC and bulbs.
Cutting your electric usage is a fun game! Good luck. If you follow my advice you should be able to cut your bill in half.
