Energy usage is a concern in most houses in the Scottsdale and Central Arizona area during our hot summers. Knowing how much energy various electronics and appliances typically use is one way to identify areas to make smart cuts to save money.
You can calculate the amount of electricity used by each item per hour pretty easily. Most appliances have the wattage that they draw on the back or bottom of the unit. Utility companies bill in kilowatt-hours. One kilowatt is equal to 1,000 watts. In order to determine the daily cost in kilowatt-hours(kWh), all you have to do is multiply the wattage by the number of hours used in a day, then divide by 1000. In order to determine how much the appliance uses annually, you multiply the kWh by the number of hours the appliance is used a day, then multiply that by the number of days in a year, which is 365.
According to the Department of Energy, one of the most expensive appliances to operate each year is the water heater. Another high energy usage appliance is the air conditioner. Some of the bite of the air conditioner can be reduced by following some simple cleaning guidelines and by adding a programmable thermostat to your unit.
When you know how to calculate energy usage from the appliances and electronics, you can make smart decisions about how to efficiently manage the power usage of items in your home. You can also weigh the benefits of updating or upgrading appliances to take advantage of higher energy efficiency in newer products.
