As far as your computer is concerned, it isn’t the largest energy hog in your house. It is a medium power drain overall using an average of 400 kilowatt-hours a year. As far as costs go, that’s only $35 on your yearly bill. However, when looked at as carbon-dioxide emissions it is equal to 530 pounds, the same as what your clothes washer produces. Looked at another way, it is less than one tenth of what your water heater creates, or 20 times the amount your DVD player produces. In brief, it’s a medium power consumer and carbon emitter.

So, why concern ourselves with the efficiency of a computer monitor? It’s because computer monitors account for over 50 percent of the energy consumed while on the computer. Moreover, even when not in use it continues to draw power; as long as it is on, the monitor is using a significant amount of wattage.
Herein lies the biggest advantage to an Energy Star-certified, high-efficiency monitor over the regular power draining models. They draw considerably less power when asleep, or off. And the sleep mode triggers automatically following a predetermined period of inactivity.
