Calculate Utility Costs

Step 1:
Make a list of systems and appliances
To understand where your utility dollars are going, you'll first need to make a list of the most energy-consuming devices in your home.
The largest part of virtually everyone's energy consumption is spent heating or cooling their home. So put the heating cooling system (if you have a air-cooling system) at the top of your list.
Now add any other products to the list that use a great deal of energy. These almost certainly include a hot water heater, a stove and a refrigerator. If you use a portable room heater, freezer, microwave, or dishwasher, also include these on your list. Don't forget the clothes washer or dryer, if you have these items.
If you own any of the following, add it to your list: an aquarium, autoblock heater, dehumidifier and humidifier, furnace fan, hot tub, water bed heater, well pump, computer color monitor or laser printer. Older color televisions with an instant-on feature also use a lot of energy. Not all households have these, and their inclusion to this list may seem petty. But they begin to add up, and together they consume more energy than their owners might expect.
