Energy-Saving Home
Office Tips
-
Selecting
energy-efficient office
equipment—personal computers (PCs), monitors, copiers, printers, and
fax machines—and turning off machines when they are not in
use can result in enormous energy savings.
-
An
ENERGY STAR®
computer uses 70% less electricity than computers without this
designation. If left inactive,
ENERGY STAR®
computers enter a low-power mode and use 15 watts or less. Spending
a large portion of time in low-power mode not only saves energy, but
helps equipment run cooler and last longer.
-
To maximize savings with a laptop, put the AC
adapter on a power strip that can be turned off (or will turn off
automatically); the transformer in the AC adapter draws power
continuously, even when the laptop is not plugged into the adapter.
-
Common misconceptions sometimes account for the
failure to turn off equipment. Many people believe that equipment
lasts longer if it is never turned off. This incorrect perception
carries over from the days of older mainframe computers.
-
ENERGY STAR®
computers and monitors save energy only when the power management
features are activated, so make sure power management is activated
on your computer.
-
There is a common misconception that screen
savers reduce energy use by monitors; they do not. Automatic
switching to sleep mode or manually turning monitors off is always
the better energy-saving strategy.
-
Long-Term Savings
Tip: Consider buying a laptop for your next computer
upgrade; they use much less energy than desktop computers.
Home Electronics Tips
- Look for energy-saving
ENERGY STAR®
home electronics.
- Many appliances continue to draw a small amount
of power when they are switched off. These "phantom" loads occur in
most appliances that use electricity, such as VCRs, televisions,
stereos, computers, and kitchen appliances. In the average home, 75%
of the electricity used to power home electronics is consumed while
the products are turned off. This can be avoided by unplugging the
new appliance or using a power strip and using the switch on the
power strip to cut all power to the appliance.
- Unplug battery chargers when the batteries are
fully charged or the chargers are not in use.
- Studies have shown that
using rechargeable batteries for products like cordless phones and
PDAs is more cost effective than throwaway batteries. If you must
use throwaways, check with your trash removal company about safe
disposal options.
