7Washers
- Front-loading ENERGY STAR models are similar in
design to washers used in laundromats. - These horizontal-axis or tumble-action machines
repeatedly lift and drop clothes, instead of
moving clothes around a central axis.
8Washers
- Top-loading ENERGY STAR washers use sensor
technology to closely control the incoming water
temperature. - To reduce water consumption
- spray clothes with repeated high-pressure rinses
to remove soap residues rather than soaking them
in a full tub of rinse water.
9 Washers
- What does this mean to you? It means..
- Nearly 50 percent less water and 30-40 less
energy used per load - Washer design causes less wear and tear on
clothes - Bulky items such as blankets fit easily in the
super capacity basket. - Better water extraction means less dryer time,
for further energy savings
10 Washers
- A typical household does nearly 400 loads of
laundry per year, using about 40 gallons of water
per full load with a conventional washer. - In contrast, a full-size ENERGY STAR clothes
washer uses 20-25 gallons per load. You could
save as much as 7,000 gallons of water per year - And, you are saving all the energy that would
have been needed to heat that water

12Refrigerator
- Your Home's Biggest Power User
- The refrigerator is the single biggest power
consumer in most households - A typical refrigerator made around 1990 uses
about over 900 kilowatt hours per year - that's
the same amount of energy you would use by
leaving a 1,250 watt hairdryer on for a month! - The older your refrigerator is, the more power it
burns
13Refrigerator
- ENERGY STAR refrigerators incorporate a number
of advanced features to save energy - Better insulation - compressor needs to run less
often to keep it cold - More efficient compressors
- Improved heat transfer surfaces
- More precise temperature and defrost mechanisms
14Refrigerator
- Also, improved insulation means that the
compressor needs to run less often. - This keeps the kitchen cooler, since the
compressor produces heat while it is running,
actually reducing the need to air condition and
improving comfort. - ENERGY STAR refrigerators must exceed minimum
federal standards for energy consumption by at
least 20.
15Refrigerator
- What about manual defrost refrigerators?
- Manual defrost refrigerators are not covered
under the ENERGY STAR program, but are generally
more efficient than automatic defrost
refrigerators. - Proper maintenance of manual defrost
refrigerators is necessary to realize the energy
savings. - The Department of Energy offers tips on buying
refrigerators and lowering the energy usage of
your refrigerator.
16Save Energy While Keeping Cool
- ENERGY STAR Room Air Conditioners feature
- high-efficiency compressors
- high-efficiency fan motors
- high-efficiency heat transfer surfaces
17ENERGY STAR Room Air Conditioners
- Air is cooled when it passes over the refrigerant
coils which have fins, similar to an automobile
radiator. - Compressor sends cooled refrigerant through the
coils, and cools the air as it is forced over the
coils. - Using advanced heat transfer technologies, more
of the heat from the air is transferred into the
coils than in conventional models, saving energy
required to compress the refrigerant.
18ENERGY STAR Room Air Conditioners
- ENERGY STAR Room Air Conditioners must exceed
minimum federal standards for energy consumption
by at least 15. - Buy The Right Size
- Many people buy an air conditioner that is too
large for the space, thinking it will cool
better. - In an oversized air conditioner will actually be
less effective than one that is the correct size,
and waste energy at the same time.
19ENERGY STAR Room Air Conditioners
- Air conditioners remove heat and humidity from
the air. - Humidity is removed when the air in a room passes
over the cooling coils of an air conditioner. - If the unit is too large, it will cool the room
quickly, but only remove a portion of the
humidity. This leaves the room with a damp,
clammy feeling to the air, since the air will not
have been circulated enough. - A properly sized unit will remove humidity
effectively as it cools.
20ENERGY STAR Room Air Conditioners
- AREA TO BE COOLED2 CAPACITY (BTU/HR)
- 100 to 150 5,000
- 150 to 250 6,000
- 250 to 300 7,000
- 300 to 350 8,000
- 350 to 400 9,000
- 400 to 450 10,000
- If the room is heavily shaded, reduce capacity by
10 - If the room is very sunny, increase capacity by
10 - If more than 2 people regularly occupy the room,
add 600 Btu/Hr for each additional person - If the unit is for a kitchen, increase the
capacity by 4,000 Btu/Hr.
21Electronic Appliances
- TVs and VCRs
- ENERGY STAR-labeled TVs require 3 watts or less
of power when switched off, an energy savings of
up to 75 over conventional models, which consume
as much as 12 watts while off. - ENERGY STAR-labeled VCRs require 4 watts or less
of power when switched off, an energy savings of
up to 70 over conventional models, which consume
as much as 13 watts while switched off.
22Electronic Appliances
23Electronic Appliances
- ENERGY STAR labeled Home Audio products consume
no more than 2 Watts when switched off. Home
audio products include cassette decks, CD
players/changers, clock radios ... - ENERGY STAR labeled DVD (digital versatile disk)
players can consume only 3 Watts when switched
off - Starting in 2003, ENERGY STAR Home Audio and DVD
products will consume no more than 1 Watt when
switched off.
24Electronic Appliances
25Office Equipment
- Energy use by office equipment is one of the
fastest-growing sources of electricity
consumption in businesses and homes - It currently accounts for more than 7 percent of
total commercial sector electricity use - Much of this energy is wasted because office
equipment sits idle for long periods.
26Fast Facts on Office Equipment
- "If over the next 15 years everyone were to buy
only those energy-efficient products marked in
stores with EPA's distinctive ENERGY STAR label,
we could shrink our energy bills by a total of
about 100 billion over the next 15 years and
dramatically cut greenhouse gas emissions."
President Clinton during a speech to announce his
climate change policy (Washington, DC), October
22, 1997
27Fast Facts on Office Equipment
- In 1999, if everyone were to purchase only office
equipment with the ENERGY STAR label, our nation
would save about 1.5 billion a year in energy
bills and cut the air pollution equal to the
amount produced by more than 3 million cars. - Most computer users don't realize that while a
screen saver is running, their monitor is not
saving energy. - For a typical American business with 100
computers, 10 laser printers and 3 copiers, more
than 4,700 is spent each year to power the
equipment. However, if the equipment is ENERGY
STAR-compliant, only 2,081 is spent on this
electricity.
28Fast Facts on Office Equipment
- An ENERGY STAR-labeled monitor consumes up to 90
percent less energy than models without power
management features. - Each year, consumers pay 1.8 billion in energy
costs just to operate office equipment used in
homes and businesses. - The average home office energy bill in the United
States is 135. However, by purchasing an ENERGY
STAR-compliant computer, monitor and fax machine,
the average home office can cut its energy bill
by as much as 45 percent.

31EXIT Signs
- As a nation, we spend about 1 billion annually
to operate all the exit signs in buildings - By the year 2000, companies could be saving 800
million kilowatts of electricity per year through
the use of ENERGY STAR-labeled exit signs. That's
a total savings of almost 70 million each year! - An ENERGY STAR-labeled exit sign operates on less
than 5 watts per face, using less energy than a
typical exit sign.
32EXIT Signs
- Each year, just one ENERGY STAR-labeled exit sign
can save about 15-20 in electricity costs when
compared with the typical, incandescent signs. - Most conventional exit signs are fitted with
typical high-wattage incandescent bulbs, which
use more electricity than newer technologies, and
need to be replaced every few months. - One exit sign can cost over 30 each year to
operate. Plus, additional maintenance costs to
replace burnt-out bulbs can reach hundreds of
dollars annually.
33Retail Partner
- More than 1,100 national and local retailers are
advertising and labeling qualified products
nationally, and many more retailers are joining
the program.. - Retail Partners receive
- Free point-of-purchase and sales training
materials - Listing on ENERGY STAR website store locator and
federal consumer information hotlines - Access to utility and manufacturer promotions

36ENERGY STAR Set-top Box Program
- The new ENERGY STAR Set-top Box Program will
include - Analog/digital cable boxes
- HDTV and DTV converter boxes
- Internet access devices (IADs)
- Video game consoles
- Direct Broadcast Satellite (DBS) systems
- Videophone set-top boxes
- Digital TV receivers
37Set-top Box Program
- WHY SET-TOP BOXES?
- Substantial Standby Power Consumption. In standby
mode (i.e., when switched off), set-top boxes
continue to consume energy, in order to provide
clock functions, remote control use, memory
maintenance, and other features. - Market Penetration. According to Cahners In-Stat
Group ("Set-top Market Frenzy," Electronic News,
February 8, 1999) the market for set-top boxes
(including only DBS, cable, and DTV boxes) is
forecasted to expand to 7.4 billion by the year
2002 from 3.9 billion last year.
38Fast Facts
- The amount of energy used when off is nearly
equal to the amount needed to operate set-top
boxes in their primary function or active mode.
(LBNL, ACEEE) - Cable, satellite, and Internet access set-top
boxes, as well as video game consoles, consume an
estimated 7 billion kWh per year, producing
pollution roughly equivalent to that of over 1
million cars. - Americans spend over 618 million on utility
bills to power these electronic devices. Set-top
boxes consume much of this energy while consumers
are not watching television or using these
products.
