Personal Computers

Volume 491: debated on Thursday 30 April 2009

To ask the Secretary of State for Health, what estimate has been made of the proportion of personal computers in each of his Department’s offices that are turned off (a) overnight, (b) at weekends and (c) during holiday periods; and if he will make a statement. (269618)

A limited deployment of energy monitoring software in December 2008 indicated that the level of personal computers not turned off overnight to be in the region of 30 per cent.

A publicity campaign on greening IT and working sustainably was initiated in January 2009, highlighting the carbon and financial cost of leaving equipment on outside working hours. The campaign has included events in communal areas and stands at all staff events. Information on greening IT has been published on the Deparment’s intranet and are included in presentations to staff. A green champions network is being launched on 8 May 2009 and the network will be used to raise awareness of sustainable working including switching off equipment when not in use

A manual survey was undertaken on 7th April outside core hours and, out of 301 PCs surveyed, 12 (around 4 per cent.) were identified as powered on. There is no data available to state whether this level varies significantly in other buildings or varies at weekends and during holiday periods. Further surveys are planned in other buildings in May and June 2009.
