Green IT in Practice: How One Company Is Approaching the Greening of Its ITOrganisations are becoming increasingly concerned about climate change and are looking at ways to reduce their environmental impact. The IT department of any organisation has a key role to play in this regard. Green IT in Practice: How One Company Is Approaching the Greening of Its IT is a reference guide that provides organisations with guidance on how to implement a green IT programme. Using the case study of UK company John Lewis Partnership, author Gary Hird explains the problems that were faced in implementing the green IT programme, as well as the solutions to the problems.

Green IT in Practice is targeted at IT professionals, management and anyone with an interest in green IT. Hird is an IT strategist for John Lewis Partnership and has worked there for more than 20 years. He has been responsible for the enterprise’s green IT infrastructure initiatives since 2006. Hird’s practical experience in the field makes the book valuable for any individual or organisation involved with green IT programmes.

Green IT in Practice begins by exploring the concept of green IT and proceeds to explain how to get started with a green IT programme. The use of metrics to measure the success of green IT initiatives is discussed in chapter three. Hird also outlines how the John Lewis Partnership engaged its staff and suppliers in its green IT initiatives, and he explains further some green IT projects that were undertaken at the John Lewis Partnership, including server virtualisation, green printing and desktop power management.

A key strength of Green IT in Practice: How One Company Is Approaching the Greening of Its IT is its case-study approach, which gives readers insight into how the John Lewis Partnership implemented its green IT programme. The teachings from this case study are invaluable to any organisation going through or intending to implement green IT initiatives.
