Waking Up To Greener IT At HM Revenue & Customs
HM Revenue & Customs (HMRC) looks right across its entire organisation for opportunities to save energy and meet strict carbon reduction targets. The IT department has an important role to play, assessing all new equipment for energy efficiency and identifying where operational improvements can help. 'Wake on LAN' automatically sets HMRC's PCs to 'Low power' when they are not being used, and triggers them to 'Wake up' for overnight updates, and after periods when they are idle during lunch breaks or while staff attend meetings. HMRC has reduced overnight PC energy usage by up to 90%, cutting electricity costs by nearly £1 million by the time Wake on LAN was fully deployed.
