ENERGY EFFICIENCY
TOPIC: COMPUTERS, COPIERS, AND PRINTERS
ISSUE:
Energy consumed by computer workstations, copiers and printers.
BACKGROUND:
Energy User News in its August 1998 issue reported:
" The Environmental Protection Agency states that operating office equipment in
U.S. businesses costs millions of dollars each year. In the average office,
computers that are turned on are in use only four hours a day. Additionally, 25
percent of computers are left running overnight and on weekends. When
equipment is left on all of the time, energy consumption for a single workstation
can total 2,500 kWh per year or from 5 to 0, depending on utility rates.
Source: Association of Energy Engineers:
Laser printers use 300 watts; ink jets use only 10, for similar quality.
A computer monitor uses 60 watts of power; it should be turned off if the
employee leaves for more than 10 minutes.
By using the stand-by button on a copier, the energy load will be lightened
by 70 %.
For three copies or less, use the printer. For more use the copier.
Recycling paper reduces energy by 70%."
