Computer Hibernate vs Logging out
From Lazer
How to calculate the cost of watts.
When a computer is not used uses 72 watts. The computer are not used for 24 * 7 * 2 - 80 = 256 hours per two weeks. The cost of kilowatt-hour is $0.13
Therefore the cost for electric when the computer in not used it $2.40 per two weeks.
If a computer is hibernated for the not used time it would use 2 watts.
Therefore the cost for electric when the computer in not used and it is hibernated is $0.07 per two weeks.
Therefore by hibernating the computer one would save $2.40 - $0.07 = $2.33 per two weeks.
The saving for one computer for the whole year would be $2.33 * 26 = $60.58.
Lets say that there is 2000 computers running at the BAE System San Diego campus then $2.33 * 2000 = $4,660.00 would be save after two weeks on the entire campus for two weeks.
The saving for the whole year would be $4,660.00 * 26 = $121,160.00.
