Appliances and electronic devices can be expensive to buy, but using them also comes at a price ā in the form of energy output. For ways to conserve energy and save on electric bills while using any of these items, please go to the Energy-Savings Floor Plan or Energy-Efficiency Tips page.
All items that use electricity have values: amps (A), volts (V) and watts (W). Using that information, you can determine just how much an item will add to your electric bill to operate. An example label from a computer monitor is shown on the right. (Please note: the range of ā100-240Vā is due to the screen being in sleep/energy saver mode or in use, respectively).
To find wattage the formula is
amps (A) x volts (V) = watts (W)
Use this Energy Usage Calculator to see just how much a specific appliance or device costs to operate. If you are unsure, look for the examples of average watt requirements below the calculator.
