3. 3 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

4. 4 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

5. 5 Single sign-on WOL web pages Central WOL server Central Backup service FiDo software installation Google Visualisation API Central PMM server Request wake on LAN Send ‘magic packet’ Request wake on LAN Send ARP query Single sign-on PMM web pages Register and wake computers Centrally provided IT services College and department networks ARP query data View graph - adjust behaviour accordingly

9. 9 Consider a population where: 20% have reduced their consumption significantly 30% consume to their heart’s desire 50% mirror the consumption patterns of people close to them What effect might the 20% have on overall consumption? a.It will decrease b.It will stay the same c.It will increase A thought experiment:

10. 10 Visibility of your action Benefit to planet Inconvenience to you a.Turn your office computer off every day after work b.Use 50% less water c.Use 50% less gas d.Use 50% less electricity e.50% fewer car miles f.80% fewer air miles over 5 year period g.Extend life-cycle of an IT device by 3 years h.Give £5 to a charity i.Give £1000 to a charity j.Persuade a friend to do any of the above k.Persuade a group (school, workplace) to do any of the above
