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

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 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
