How much does this cost on my utility bill?

Appliances and electronic devices can be expensive to buy, but using them also comes at a price – 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.

Get amped about saving electricity!

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 “100-240V” 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)

Is it energy efficient?
