New computer management reduces unneeded energy usage
SACRAMENTO—The California Department of Corrections and Rehabilitation (CDCR) will save approximately $750,000 per year with a new energy-saving program that shuts down the department’s approximately 34,000 networked personal computers (PC) after a period of inactivity.
As the largest state agency in California, CDCR sought ways to reduce power costs and energy by at least 20 percent as part of the statewide Green Initiative.
To measure its energy use, CDCR hired Verdiem, an Information Technology (IT) energy management and efficiency software company. Verdiem’s Surveyor software determined the department’s baseline annual energy cost at $2.65 million.
CDCR used Surveyor to establish power management policies that would determine when to shift PCs into lower power states. Under the new policy, workstations go to sleep after 7 a.m. following two hours of inactivity. At 5 p.m., workstations go to sleep if inactive for 30 minutes. After 10 p.m., the workstations wake for software patches and a virus scan, and then go to sleep until 7 a.m.
CDCR employees were previously encouraged to shut down computers at night to save energy, but using the Surveyor software to automatically shift PCs into sleep mode, the department was able to achieve and sustain an additional 28 percent reduction in energy use.
In addition to the cost savings, the savings in carbon emissions helped CDCR reduce its carbon footprint and reach its compliance goal with California’s Green Initiative for public agencies.
“Green IT remains a key strategic priority for CDCR,” Director of the Division of Enterprise Information Services for CDCR Joe Panora said. “We will continue to explore IT solutions to reduce our overall greenhouse gas emissions and power consumption.”
