Calculate The Potential Annual Savings From Power Managing Your Computers

Basic     Advanced
Use the basic calculator inputs below to estimate your energy and dollar savings from activating power management on your computer monitors and your computer boxes (CPU, hard drive, etc.). Enter the number of units to be power managed and the price of electricity (Average cost per kWh in Australia is 12 cents, the default).

For a more advanced calculator, that allows you to adjust your default settings, click on the Advanced tab above.

* Power management places your computer into a low-power sleep mode during periods of inactivity. The computer “awakens” upon touching the keyboard or mouse.
1 Number of Units to Be Power Managed is the number of computer monitors or computer boxes (CPU, hard drive, etc.) that need to be power managed. In general, computer boxes are rarely power managed, so enter the number of PCs in your organization as the number of “computer boxes that need to be power managed”. However, depending on your organization, computer monitors are sometimes already set to go to sleep. So enter only the number of computer monitors that ARE NOT already set to go to sleep.
6 Number of Homes Lit represents the number of homes that would be lit for a year by the energy saved by power management. Based upon 1,250 kWh/year used on lighting by the average home. (Based on EPA data.)
7 Lbs CO2 represents the pounds of carbon dioxide from electricity generation emissions avoided due to energy savings from power management. Based upon a conversion of 1.43 lbs. CO2 per kWh electricity generated. (Based on Energy Information Agency data.)
8 Tons CO2 represents the tons of carbon dioxide from electricity generation emissions avoided due to energy savings from power management. 2000 pounds equals one ton.
9 Cars Off the Road represents the pounds of carbon dioxide from car emissions avoided due to energy savings from power management. Based upon a conversion of 11,560 lbs. CO2 emitted per year by a car. (Based on EPA data.)
10 Acres of Trees Planted represents acres of forest that would have to be planted to sequester the amount of carbon dioxide avoided due to energy savings from power management. Based upon a conversion of 7,333 lbs. CO2 sequestered per acre of trees. (Based on EPA data.)
