Wattson's Home Energy Quiz
Questions and Answers
- 1.
What initial step should you take to help reduce energy costs around the house?
- A.
Locate & seal drafts around doors, windows, baseboards with caulk or weather stripping.
- B.
Add insulation to the attic and basement, such as open wall tops & ducts.
- C.
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.Rate this question:

The energy used in your home can be responsible for how much more pollution than your car?
- A.
Three times as much
- B.
Twice as much
- C.
Half as much
- D.
My house causes pollution, too?
Correct Answer
B. Twice as muchExplanation
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:

When is the best time to use a ceiling fan?
- A.
Winter, when warm air needs to circulate in the house
- B.
Summer, when its hot outside
- C.
Both Winter & Summer
Correct Answer
C. Both Winter & SummerExplanation
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:

How Much power does a Compact Fluorescent Light Bulb (CFL) use compared to a standard light bulb?
- A.
One-Tenth
- B.
One-Third
- C.
Half
- D.
Two-Thirds
Correct Answer
B. One-ThirdExplanation
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:
