Green Computing and Office Energy Use Savings Suggestions
It does not use more energy to turn equipment on and off.
Additional Things Individuals Can Do
Check the Energy Star website for energy efficiency ratings for home and office equipment and appliances, home improvement suggestions, savings calculators and more. ENERGY STAR is a government-backed program helping businesses and individuals protect the environment through superior energy efficiency. For information on end of life management of CFLs, or if you break a CFL, check out the fact sheet from NHDES.

Computer Power Management and Energy Savings
Turning off a computer before going to sleep or when it isnt going to be used for a few hours is a good habit to develop.
One of the goals of the Presidents Council for a Sustainable Future is to reduce the amount of energy per kilowatt hour (kWh) used on campus. Turning off computers and all of the peripheral equipment (printer/monitor/speakers) when not in use can save Keene State College thousands of $$$. See the grid below.

Plus, computers generate heat and require additional cooling which adds to energy costs.
In 2005, an average of 1.55 pounds of CO2 is produced per kWh

Enabling Power Management Features
Power management, when enabled, allows computer monitors to go into a low-power sleep mode during periods of inactivity. Then, instead of paying utility bills for computer monitors that are kept on all day and night, we pay only for the time that the computers are in use. For large organizations like ours, this single step leads to annual savings of thousands of kilowatt-hours and dollars. A typical college or university, for example, can expect to save 200,000 kilowatt-hours per year, or about $20,000 in energy bills, for every 1,000 monitors.
Other savings include lowered cooling costs and longer lives for the equipment.
EPA Energy Star Computers and monitors can be programmed to automatically power down to a low power mode when they are not being used.
To save energy with your monitors' built-in power management system, your monitor must go blank. If screen saver images appear on your monitor for more than 5 minutes, you are wasting energy!
About Screen Savers"Screen savers" were originally designed to save the phosphors in the monitor screen from "burning" an image onto the screen, but they do not save energy. A screen saver that displays moving images consumes as much electricity as it does when in active use. A blank screen saver is slightly better, but even that only reduces monitor energy consumption by a few percent. Use your Energy Star compliance features. The equipment is designed to be efficient without any effort from you. It's easy and it makes a difference.

Computers should not be thrown in the trash. KSC users have several options for disposal of their computer equipment.Monitors and Hard Drives contain lead, cadmium, nickel, gold and other heavy metals. Your options include:
CD's, DVD's, floppy disks are all recyclable. Please put in an envelope and mail to R.O.C.K.S. at MS2502
Ink Jet cartridges are all recyclable. Ink Jet recycling containers are located near the Bursar's Office in Elliot Hall, at the Mason Library (1st floor near the phones) and other convenient locations on campus. You can also get send them to R.O.C.K.S. MS 2502.
