Calculating Energy Usage – It’s Easier Than You Might Think

calculate energy usageLiving in Greater Los Angeles isn’t cheap, but that doesn’t mean you have to put up with high energy bills. Calculating energy usage at home will show you where you can trim your usage and cut your energy bills.

Consider How Much You Use Your Appliances

Start by making a list of all the lights, appliances, and other electronics in your home that use electricity. Then calculate how many hours a day you use each one. For example, if you have a living room lamp on for one hour in the morning and five hours in the evening, that’s six hours of daily use.

For appliances that cycle on and off, such as your refrigerator or heating and cooling system), divide the amount of time they’re plugged in and turned on by three. This accounts for the time they’re “on” but not actually running. Don’t forget appliances you might not use every day, such as your washing machine or dishwasher. If you’re not sure how often you use each electrical item, keep a log for a week.

Calculate Your Appliances’ Energy Use

You’ll usually find an electrical item’s wattage stamped somewhere on it. This is the maximum amount of power the item can draw. Electronics with a range of settings draw less power when on a lower setting. To calculate how much energy an item uses, use the formula: (wattage × hours used per day) / 1000 = kilowatt-hour (kWh) used per day. For appliances you don’t use daily, take the daily average of the hours you use it. Calculate the daily usage for each appliance and add them up to find the daily consumption for your whole home.

To find how much each electrical appliance costs you, check your electric bill for the amount you pay per kWh. Multiply that amount by the appliance’s daily consumption in kWhs.
