Office equipment,
such as computers, monitors, printers, copiers, and fax machines,
is one of the fastest growing energy load in the business world.
Each year, $1.8 trillion are spent on the energy costs associated
with operating office equipment.
Many of these pieces of equipment can be used
more efficiently to cut energy costs. Or, when you are purchasing
new equipment, you can look for energy-saving features,
especially on equipment labeled "ENERGY STAR." A
typical company can save 30% of the energy costs of running its
office equipment.
Computers
Energy use by computers could double by the
year 2000. Unfortunately, much of the energy associated with
computers is wasted because PCs are often kept on while not in
use. This is why it is important to purchase a computer
advertised as an ENERGY STAR model, that automatically "goes
to sleep" when not in use.
- ENERGY STAR computers automatically power
down to 30 watts or less when not in use.
- ENERGY STAR computers are available at no
additional cost to you and can actually save you anywhere
from $7 to $52 per year in electricity bills.
- ENERGY STAR computers may actually last
longer than conventional products because they spend a
large portion of time in a low-power sleep mode. By
purchasing an ENERGY STAR computer and remembering to
turn it off during long periods of non-use, it can
actually last ten times as long as a conventional
computer.
- ENERGY STAR computers generate less heat
than conventional systems. Upgrading your existing
equipment to ENERGY STAR can lead to cooling reductions
of up to 25 percent. This can create a more comfortable
work space for you and your office mates.
- ENERGY STAR computers also tend to be
quieter than conventional computers since some have no
noisy fans.
Monitors
A significant portion of the energy used in
offices is consumed by monitors. However, monitors equipped with
a power-management feature can save 60 to 80 percent of energy
that would otherwise be wasted. New trends toward larger desktop
monitors, color, and higher resolution have increased the amount
of energy required to operate monitors. This has made it even
more important to choose an ENERGY STAR monitor that
automatically powers down when inactive.
- ENERGY STAR monitors automatically power
down to 30 watts or less when not in use. To wake up a
monitor, all you have to do is simply touch the keyboard
or mouse.
- ENERGY STAR monitors emit less heat into
the workplace than conventional monitors. This means you
will save on your utility bills from heating and cooling
load reductions.
- Sleeping ENERGY STAR monitors emit fewer
electromagnetic fields (EMF) since they are not
displaying any visual image when "asleep."
Printers
Printers are typically left on 24 hours a day,
but are active only a small percent of the time. This means
conventional printers can waste a lot of energy and money. A
better option would be to purchase an ENERGY STAR printer that
goes to sleep when not in use.
- ENERGY STAR printers automatically power
down to 15-45 watts, depending on the number of pages per
minute produced. This automatic "power-down"
feature could cut a printer's electricity use by over 65
percent.
- In addition, choosing a printer with a
duplexing mode can save a company $30 a month in paper
costs.
- Using the power-management feature means
your printer will produce less heat. This contributes to
a cooler and more comfortable work space, and reduces
air-conditioning costs.
- By generating less heat, your printer may
last longer and be more reliable.
- Consider printer sharing devices such as a
manual printer switch that can route jobs to the printer
when the switch is set to receive incoming signals from
one of two or more computers.
- Turn printers off at night, on weekends
and during extended periods of inactivity.
Copiers
Approximately 7 million copiers are currently
in use in homes and businesses across the U.S., and over 1.5
million new copiers are sold each year. Copiers are the most
energy-intensive type of office equipment. Because copiers waste
energy by sitting idle for several hours each day, there is great
potential to improve the energy efficiency of copiers in a
variety of ways.
- ENERGY STAR copiers are equipped with a
feature that allows them to automatically turn off after
a period of inactivity, reducing a copier's annual
electricity costs by over 60 percent.
- High-speed copiers are set to
automatically make double-sided copies, reducing paper
costs by $60 a month.
- Using less paper also saves energy because
it takes ten times more energy to manufacture a piece of
paper than it does to copy an image onto it.
- If everyone used ENERGY STAR copiers, the
amount of paper used could be reduced from more than 700
billion sheets to 500 billion sheets. This adds up to a
savings of 1 million tons of paper, enough to go around
the would 1,400 times!
Fax Machines
Fax machines are generally turned on 24 hours
per day. However, they are only actually in use for about 5
percent of the total time that they are turned on! ENERGY STAR
fax machines are designed to save energy by being programmed to
reach a low-power state after a specified period of inactivity.
- ENERGY STAR fax machines are equipped with
the power-management feature and can reduce energy costs
by almost 50 percent.
- A medium-speed ENERGY STAR fax machine
uses 25 percent less energy in sleep mode than in standby
mode when it is immediately ready to send/receive faxes.
- ENERGY STAR faxes can scan double-sided
pages. This will reduce both your copying and your paper
costs.
- Consider using recycled toner cartridges
and recycled paper to reduce the flow of solid waste that
ends up in national landfills.
- Using a full-page cover sheet for each fax
transmission can greatly increase the amount of paper
used when faxing a message. Stick-on labels that are
placed on the first page of the fax message not only
reduces the amount of energy and paper used, but can also
save on telephone charges.
