    What initial step should you take to help reduce energy costs around the house?

    • Locate & seal drafts around doors, windows, baseboards with caulk or weather stripping.

    • Add insulation to the attic and basement, such as open wall tops & ducts.

    • Turn off heating & air conditioning system when you're away.

    Correct Answer
    A. Locate & seal drafts around doors, windows, baseboards with caulk or weather stripping.
    Explanation
    Sealing up your home is one of the most cost effective ways to improve your home’s comfort and reduce energy costs. Hidden gaps and cracks in a home can add up to as much airflow as an open window and cause your heating and cooling system to work harder, use more energy, and cost more.

    Next, inspect your attic, to be sure it’s properly insulated — it’s the easiest place to add insulation and make a big impact on energy bills. Together, sealing air leaks and adding insulation can reduce your annual energy bill by 10 percent and improve comfort.

    When is the best time to use a ceiling fan?

    • Winter, when warm air needs to circulate in the house

    • Summer, when its hot outside

    • Both Winter & Summer

    Correct Answer
    A. Both Winter & Summer
    Explanation
    Ceiling fans improve comfort in both winter and summer. During winter, run them clockwise (upward motion) at a low speed, to circulate heat that gathers near the ceiling. In summer, or in hot climates, run them counterclockwise (or downward) to cool. Most fans have a switch to reverse the spin. When cooling, always turn off your ceiling fan when you leave the room, just as you do your lights (a fan only cools you, not a room, by creating a “wind-chill effect”).

    Rate this question:

  • 4. 

    How many degrees must you dial down your water heater's thermostat to knock 3 to 5 percent off your water-heating bill?

    • 10 Degrees

    • 15 Degrees

    • 20 Degrees

    • 25 Degrees

    Correct Answer
    A. 10 Degrees
    Explanation
    You must dial down your water heater's thermostat by 10 degrees to knock 3 to 5 percent off your water-heating bill. Most water heaters come preset at 140 degrees, which has the added risk of scalding. The Energy Department recommends most households lower it to 120 degrees.

    Rate this question:

  • 5. 

    How long does it take for a standard 100-watt light bulb to consume 100 watts of energy?

    • 1 Minute

    • 30 Minutes

    • 1 Hour

    • 6 Hours

    Correct Answer
    A. 1 Hour
    Explanation
    It takes 1 hour for a 100-watt light bulb to consume 100 watts of energy.

    Rate this question:

  • 6. 

    How Much power does a Compact Fluorescent Light Bulb (CFL) use compared to a standard light bulb?

    • One-Tenth

    • One-Third

    • Half

    • Two-Thirds

    Correct Answer
    A. One-Third
    Explanation
    An ENERGY STAR-qualified compact fluorescent light bulb (CFL) will save about $30 over its lifetime, and pays for itself in about 6 months. Upgrading 15 of the inefficient incandescent light bulbs in your home could save you about $50 per year.

    Rate this question:

  • 7. 

    The cost of heating water for your home may amount to as much as what percent of your entire utility bill?

    • Under 5%

    • 5%-10%

    • 15%-20%

    • 25%-30%

    Correct Answer
    A. 15%-20%
    Explanation
    The cost of heating water for your home may amount to as much as 15-20 percent of your entire utility bill depending if it is a gas, oil, or electric heater.

    Rate this question:

  • 8. 

    The energy used in your home can be responsible for how much more pollution than your car?

    • Three times as much

    • Twice as much

    • Half as much

    • My house causes pollution, too?

    Correct Answer
    A. Twice as much
    Explanation
    Making your home more energy-efficient helps to reduce air pollution and prevent global warming. The average house is responsible for twice the greenhouse gas emissions as the average car, annually (22,000 lbs. vs. 11,500 lbs.). That’s because every time you flip on a light switch, run your dishwasher or turn on your air conditioner or furnace, you use energy, which means more pollution from power plants. The more energy we save at home, the more we can help protect the environment.

    Rate this question:

  • 9. 

    If you can do one thing only to save on electricity, which one would have the most impact.

    • Use power strips with on/off switches

    • Unplug TVs you don't use regularly.

    • Unplug chargers and adaptors

    • Limit the time you use clothes dryers

    Correct Answer
    A. Limit the time you use clothes dryers
    Explanation
    While its important and helpful to be aware of energy vampires, your energy footprint shrinks dramatically when you stop over-drying clothes and linens.

    Rate this question:

  • 10. 

    Which electrical device uses the most standby power?

    • Garage-door opener

    • Cordless phone

    • Microwave

    • Cable Modem

    Correct Answer
    A. Garage-door opener
    Explanation
    Generating the electricity needed to keep the opener ready means emitting more than 50 pounds of CO2 a year.
