 According
to the Rocky Mountain institute you could save enough electricity by turning
off a standard pc monitor and printer at night and over weekends to pay
for the price of a computer within a few years!(from Earth Limited -50
simple things your business can do to save the environment, Greenleaf
publishing)
- turning off 10 monitors when not being used could save £200
a year in energy costs (from Earth Limited -50 simple things your
business can do to save the environment, Greenleaf publishing)
- Computer monitors use up to 50% of the total energy needed to run
a p.c.
- PCs, monitors and other office equipment not only use lots of energy
but also generate lots of heat, raising temperatures above the optimum
19deg C. In non air-conditioned offices this means staff will often
open windows, use desk fans (both wasting energy) to cool themselves
down. In air conditioned offices this heat will put extra strain on
the air conditioning system (also using more energy).
- It is quite safe to switch off computers, monitors, printers and
copiers, particularly if they are not going to be used for more than
15 minutes.
- Some people may be reluctant to keep starting up/ shutting down
computers due to time delay. In this case just switch off the monitors.
- Screen savers definitely do not save energy, even if they are blank
you energy is used to display a black screen!
