Strategy A - Leave computers on all year: 110/1000 x (24 x 365) x 16,000 x £0.12 = £1,850,112
Strategy B - Power them down after work: 110/1000 x (10 x 223) x 16,000 x £0.12 = £470,976

Why are idle computers left on?
1. To allow IT managers to install software updates and make backups
2. So computers can be accessed remotely by end-users
3. Sleep mode (ACPI S3) is unreliable
4. People forget to power them down
5. People don’t like to wait for their computer to start up
