What can be done with distributed IT?

• Verizon Wireless
• To help reduce energy costs at its Chandler,
  Ariz., Albuquerque, N.M., and Irvine, Calif. call
  centres
• installed SUN thin clients which run on four
  watts of electricity
• reduced its total energy usage at each facility
  by 30 percent
• Thin clients have a lifespan of up to ten years,
  fewer parts end up in a landfill
• Also using 1E software utility which
  significantly reduces the power consumed by PCs

• DEFRA
• Design of distributed IT baseline approach
• Tools and sampling approach tested
• Observed potential for 20 - 30 power savings in
  Distributed IT
• Enable energy saving features, disable screen
  savers
• Match equipment to user profile
• Intelligent management of shared devices e.g.
  printers
• Design energy-efficient IT architectures
• Distributed IT Baseline
• 12,000 users across DEFRA and 10 Executive
  agencies, 200 buildings, 30 data centres
