Energy Conservation 101
The American Association
of Blacks in Energy ®
Mission
The American Association of Blacks in Energy (AABE)
is a national association of energy professionals
founded and dedicated to ensure the input of African
Americans and other minorities into the discussions
and development of energy policies, regulations,
R&D technologies and environmental issues in the
United States.
Purpose
•
To serve as a resource for policy discussion of the economic, social and
political impact of environmental and energy policies on African
Americans
and other minorities.
•
To ensure involvement of African Americans in governmental energy
policymaking by recommending capable, sensitive and informed
personnel to appropriate officials.
•
To encourage both the public and private sectors to be responsive to the
problems, goals and aspirations of African Americans in energy-related
fields.
•
To encourage African American students to pursue careers in energyrelated fields and to provide scholarships and other financial aid for such
students.
Home Energy Usage

monthly
Heating & Cooling
•Thermostat settings
•68° Winter / 78° Summer
•3% - 5% decrease in usage for every degree of adjustment
•Install programmable thermostats (No advantage if you don’t
program)
•Sealed ductwork
•Blocked vents/registers
•Dirty filters
•Service unit regularly
•Unit SEER* rating < 10
•Energy Star ~20% more efficient

Water Heating
• I want HOT water (120° F adequate)
• Size tank to meet demand
• Hot, filled to the rim bath
• Enjoy now, pay later
• Take quick shower
• Low flow faucets/shower heads
– Can reduce consumption up to 50%
• Instantaneous or Demand Water Heaters
– Consider size of family
– Electrical panel capacity (14kW – 30kW)
– Professional installation
– Circuits require professional (qualified) technician
– Water minerals shorten life

Energy Star Appliances
What Makes a Product ENERGY STAR?
ENERGY STAR products are the same or better than
standard products, only they use less energy. To earn
the ENERGY STAR, they must meet strict energy
efficiency criteria set by the US Environmental
Protection Agency or the US Department of Energy.
Since they use less energy, these products save you
money on your electricity bill and help protect the
environment by causing fewer harmful emissions from
power plants. And you get the features and quality you
expect.
Energy Star Appliances
Some examples:
•Qualified refrigerators are at least 15% more efficient than the
minimum federal efficiency standard.
•Qualified TVs consume 3 watts or less when switched off, compared
to a standard TV, which consumes almost 6 watts on average.
•Qualified light bulbs (CFLs) use two-thirds less energy than a
standard incandescent bulb and must meet additional operating and
reliability guidelines.
•Qualified furnaces offer a rating of 90% AFUE or greater, which is
about 15% more efficient than the minimum federal efficiency
standard.
Energy Star Qualified Home
ENERGY STAR qualified homes achieve energy savings through
established, reliable building technologies. Builders work with Home
Energy Raters to select from a number of features when planning and
building homes.
• More Effective Insulation
• High-Performance Windows
• Tighter Construction and Ducts
• Efficient Heating and Cooling Equipment
• Lighting and Appliances
• Third-Party Verification
Energy Star Qualified Home
