Power Management

Green Campus Committee

Information Technology (IT) collaborates with Missouri S&T's Green Campus Committee (GCC) Icon indicated a new window/tab will be opened by pressing link in promoting sustainability. IT feels that it is important to integrate environmental, societal, educational and economic goals to protect and enhance our natural resources so that future generations can enjoy a quality of life equal to or greater than our own.

IT encourages students, faculty and staff to join in the effort to conserve energy by changing their Power Management settings and turning off their Screen Saver:


What is Power Management?

Power management is a process that allows monitors and computers (CPU, hard drive, etc.) to enter low-power states when sitting idle. The low power modes of inactive computers can involve reducing power consumption or spinning down the hard disk. Inactive monitors with enabled power management enter low-power modes by turning off monitor output. By simply hitting the keyboard or moving the mouse, the computer or monitors awakens from its low-power “sleep mode” in seconds.


Why is Power Management Important?

It is important to utilize power management settings on computers to save cost and produce large amounts of energy without interference to the end-users, and at the same time lessening the burden on IT staff. On average, each computer workstation can save 200 kilowatt-hours (kWh) per year. Assuming the electricity rate is $0.10/kWh (the average electricity rate), a network with 1,000 workstations can save $20,000 per year with power management.


Common Questions:

Should I turn off my monitor when not in use?
Absolutely!  Many newer models put the monitor to sleep, but turning it off helps ensure unnecessary power isn't used, especially if you're using an older computer.

Should I turn off my computer every day when I leave work?
IT recommends that you log out, but leave your computer powered on so we can push important security updates, when needed.  However, adjusting your computer's power settings can minimize its energy usage while you're away, so that it uses only a tiny amount of electricity.
