Understand Your Usage
How much electricity you use varies from day to day and month to month, depending upon a variety of factors including how many people are in your home, your daily habits, the weather, and the time of year.
Now that summer is here, stay cool and comfortable while understanding energy costs
Cooling costs: save money and maintain your comfort. Here are some tips:
- Raise the thermostat on your air conditioning by two degrees and use your ceiling fan; you can lower cooling costs by up to 14 percent.
- Use bedroom fans on those cooler summer nights and naturally cool your home.
- Buying a new window air conditioner? Look for an ENERGY STAR® rating on it and use 15 percent less energy to stay cool.
- If your central air system is more than 12 years old, consider replacing it with an ENERGY STAR® certified model. This could lower your cooling costs by as much as 30 percent.
- Heat pump systems offer an energy-efficient alternative to furnaces and air conditioners. High-efficiency heat pumps dehumidify the air better than standard central air systems, resulting in less energy usage and more cooling comfort in summer months. For homes without ducts, air-source heat pumps are also available in a ductless version called a mini-split heat pump.
Your electricity use — it's simple math:
For example: How much energy does my window air conditioner use?
|A window air conditioner||= 900 watts|
|Divide that wattage by 1,000 to get the # of kilowatts||= 0.9 kilowatts|
|Multiply the kilowatts (0.9) by the number of hours used (8) (equals one day)||= 7.2 kWh (number of kilowatt hours used to cool your home)|
|Multiply the kWh (7.2) by the cost (14.9 cents per kWh*)||= $1.07 (cost per day)|
*The total cost per kWh for customers with Standard Offer supply is 14.9 cents (As of July 1,2020 CMP delivery is 7.6 cents and Standard Offer Supply is 7.3 cents) Your supply rate may vary if you have selected a different supplier – check your bill for your supply price.
How does that apply* to other cooling sources?
|Cooling Source||watts||kilowatts||hours||kWh||daily cost|
|Window Air Conditioner||900||0.9||8||7.2||$1.07|
|Central Air System||3000||3||8||24||$3.58|
|Heat Pump System||1210||1.21||8||9.68||$1.44|
*May vary depending on number of run hours and temperature settings. Watts are average equipment watt usage for typical equipment as identified by ENERGY STAR®

Tips to help you manage your energy use while spending time at home
- Turn off lights whenever you leave a room or don't need them
- Use task lighting over desks, tables and workbenches
- Take advantage of natural light whenever possible
- Use the air-drying option instead of heat drying. Or better yet, turn off the drying cycle, open the dishwasher and let the contents air dry
- Keep your refrigerator temperature setting just low enough to chill milk (38-40 degrees F) and the freezer low enough to keep ice cream hard (around 5 degrees F)
- Did you know, every time you open your refrigerator, approximately 30% of the cold air escapes?
- Instead of opening your oven door to check what’s cooking look through the window.
- Use advanced power strips to eliminate any ‘standby’ power that many devices consume even when turned off.
- Set your water heater at 120 degrees F (Many are preset at 140 degrees F)
Wonder how much electricity all the different items in your home use?

Use the miscellaneous section of the calculator to complete the calculation above for a single appliance!
- To estimate the hours used, think about how your appliances operate – does the appliance cycle on and off all day? Is it on steady for 8 to 10 hours?
- Look at your billing period – remember your monthly bill may not be a calendar month.
- Look at your bill to find the cost of your delivery charges (page 2) and your electricity supply (page 3).
