The ANUgreen Team recently logged the energy usage of a desktop PC to determine energy usage levels in different operational modes. The results are as follows.
17 inch monitor (running)
66 watts
17 inch monitor (sleep mode)
2.6 watts
Computer (on but not in use*)
32 watts
Computer (hard disk sleeping)
27.5 watts
Computer (standby mode)
4.3 watts
*Energy usage of the computer will fluctuate during use as the hard drive is accessed. The figure recorded here is the baseline usage.
Hat tip to Phil Johnson for finding these figures. He also includes some other links that may help direct decisions about computer usage.
