To ask the Secretary of State for Work and Pensions what estimate he has made of (a) the number of computer devices left on overnight in his Department when not in use and (b) the cost of leaving computer devices on overnight when not in use in each of the last five years; and if he will make a statement. (217873)

Statistics on the numbers of instances (and therefore any total related costs) are not available, and to obtain them would be at disproportionate cost. The Department for Work and Pensions recognises that PCs being left on overnight waste energy and as a result, instructs and regularly reminds staff to turn off PCs at the close of their working day.
