money issue. Saving money is its own reward.
So, my suggestions:
1. Pay for an energy audit. Somebody should come out with a thermal camera and various meters. Expect this to cost a couple hundred, though I think there are some federal programs that you can use to get the money back. There may be state programs. There are some stuff so you can deduct it and any improvements, but consult the experts in the tax field.
The thermal camera can help determine if you have any glaring holes in your home's installation and give you an idea of where to target for improvements. The meters are to determine how much power your various appliances are actually using. Remember, faceplate is their maximum draw, and is for safety. Average can and should be lower. You could have a bum appliance that's just sucking down power. A continuous 1000 watts might not be that noticeable in a major appliance, but will really add up.
If you want to go it yourself, a kill-o-watt can help track down for your 'minor' appliances - anything 120V.
For the AC system, water heater, and such, a clamp ammeter and a hour meter might be your better choice. I say an hour meter because things like a water heater draws the same amount of power whenever it's running, so a hour meter and a bit of multiplication gives you the kwh used.
But if you really want a meter, $90 seems to be the starting point:
