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 cooler months are here, stay comfortable while understanding energy costs
Heating costs: save money and maintain your comfort. Here are some tips:
- Set the thermostat as low as comfort permits. Each degree above 68º F can use 3% more energy.
- Install a programmable or wi-fi thermostat to automatically control your heating and save money by lowering the temperature when you’re not home.
- If you use electric heat, consider replacing it with a high efficiency ductless mini split heat pump system, which can lower electricity use by as much as 40%.
- Clean or replace furnace filters as recommended and have your furnace burner checked and cleaned annually by a contractor. A well cleaned and tuned heating system saves you money.
- Install high-efficiency LED lighting. LED lighting uses 90% less energy than standard incandescent bulbs and lasts up to 25 times longer.
Your electricity use — it's simple math:
For example: How much energy does my lighting use?
|LED Lightbulb (60-watt equivalent)||= 9.5 watts|
|Divide that wattage by 1,000 to get the # of kilowatts||= 0.0095 kilowatts|
|Multiply the kilowatts (0.0095) by the number of hours used (10) (equals one day)||= 0.095 kWh (number of kilowatt hours used by the light bulb)|
|Multiply the kWh (0.095) by the cost (14.0 cents per kWh*)||= $0.013 (cost per day)|
*The total cost per kWh for customers with Standard Offer Supply is 14.0 cents.
(As of July 1,2020 CMP delivery is 7.6 cents and as of January 1, 2021 Standard Offer Supply is 6.4 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 lighting sources?
|Lightbulb Type||watts||kilowatts||hours||kWh||daily cost|
Now multiply these figures times the number of bulbs and you can see the energy savings for more efficient lighting can really add up.
*May vary depending on number of run hours and bulb wattage choice. Watts are average usage for typical lighting solutions 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).
