Chap 1 - Good time to act

It is irrelevant how much any of us agree that we need to reduce costs and greenhouse gas emissions, the only thing that matters to our budgets and the environment is whether we act on these beliefs. We cannot ignore energy prices any more, disparaging efficiency initiatives because the human resource cost is too high: "my time is too valuable to merit the tiny reduction in energy consumption that switching a computer off at the end of each working day". How can anybody know whether such a statement can be true, what is the long term price of a unit of greenhouse gas emissions?

Chap 2 - Things to do

Reducing energy consumption by turning computers reliably and safely to a low-power state is most definitely a worth while gesture to make, especially if everyone does it.

Chap 3 - Full life-cycle considerations

Chap 6 - Objections

• Myths:
  • Turning a computer off increases the chance it will break
  • Uses more energy to boot a system
  • Good way of heating the room so reduce gas bills
