Use power strips to switch off televisions, home theater equipment and stereos when
you're not using them. Even when you think these products are off, together, their
"standby" consumption can be equivalent to that of a 75 or 100 watt light bulb running
Set Computers to Sleep and Hibernate
Enable the "sleep mode" feature on your computer, allowing it to use less power during
periods of inactivity.
Take Control of Temperature
Use sunlight wisely. During the heating season, leave shades and blinds open on sunny
days, but close them at night to reduce the amount of heat lost through windows.
Close shades and blinds during the summer or when the air conditioner is in use or
will be in use later in the day.
Use Appliances Efficiently
Use the power-save switch if your fridge has one, and make sure the door seals tightly.
You can check this by making sure that a dollar bill closed in between the door gaskets
is difficult to pull out. If it slides easily between the gaskets, replace them.
Don't preheat or "peek" inside the oven more than necessary. Check the seal on the
oven door, and use a microwave oven for cooking or reheating small items.
Wash only full loads in your dishwasher, using short cycles for all but the dirtiest
dishes. This saves water and the energy used to pump and heat it. Air-drying, if you
have the time, can also reduce energy use.
In your clothes washer, set the appropriate water level for the size of the load;
wash in cold water when practical, and always rinse in cold.
Clean the lint filter in the dryer after each use. Dry heavy and light fabrics separately
and don't add wet items to a load that's already partly dry. If available, use the
moisture sensor setting. (A clothesline is the most energy-efficient clothes dryer
Don't forget to flick the switch when you leave a room.
Remember this at the office, too. Turn out or dim the lights in unused conference
rooms, and when you step out for lunch. Work by daylight when possible. A typical
commercial building uses more energy for lighting than anything else.
Look for the Energy Star® label
Energy Star models are the most energy efficient in any product category, exceeding
the energy efficiency minimums set by the federal government. CheckEnergy Starfor details.
Energy-Saving Purchasing Tips
New refrigerators consume 75 percent less energy than those produced in the late 1970s.
A family replacing a 1980 vintage fridge with one that meets today's standards will
save more than $100 a year in utility costs.
Refrigerators with freezers on top use 10 to 15 percent less energy than a side-by-side
model of equivalent size.
Generally, the larger the refrigerator, the greater the energy consumption. But one
large refrigerator will use less energy than two smaller ones with the same total
volume or a smaller fridge plus a separate freezer.
Choose the right size washer. A smaller washer may be more efficient for small households.
But if you have a large family and have to do multiple loads in a washer that's too
small for your needs, you could lose any possible energy savings.
Look for a washer with adjustable water levels. This gives you the option of using
less water to wash small loads.
Choose a washer with a faster spin speed. This allows more water to be removed after
the wash, reducing the drying time and your dryer's energy use.
Use a gas dryer rather than an electric dryer where possible.
The most efficient dishwashers use less hot water, have energy-efficient motors and
use sensors to determine the length of the wash cycle and the water temperature needed
to do the job.
Choose a dishwasher with a "light wash" or "energy-saving" wash cycle. It uses less
water and operates for a shorter period of time for dishes that are just slightly
Look for dishwashers that have an energy-saving cycle that allows dishes to be air-dried
with circulation fans, rather than heat-dried with energy-wasting heating coils.
Ink jet printers tend to be more energy-efficient than lasers.
LCD televisions and monitors draw less power than CRT or plasma screens.
Small lightweight power supplies tend to be more energy efficient than large, heavy
transformer-based power supplies.
Use the Internet
Several websites contain additional useful information. The EPA's Energy Star website
has information on appliance models that carry the Energy Star label and where you
can buy them. The American Council for an Energy Efficient Economy publishes a yearly
list of the most energy-efficient appliances. And the Consortium for Energy Efficiency
has information on programs promoting energy efficiency in the home.
Leaving doors wide open to a room or building may make it more inviting to come in,
but it wastes energy. Don't prop doors open but allow them to close after people walk
through the doorway.
