2. B. 78 degrees is the ideal temperature setting for summer.

3. A. Program the thermostat to raise the inside temperature when you are gone for four or more hours.

4. False. Close garage doors to conserve energy.

5. C. Each degree below 78 degrees adds six percent to your cooling costs.

6. True. Keep drapes closed or add room-darkening shades to block out heat from the sun.

7. False. Keep all storm windows and doors closed when the heating or cooling system is on.

8. B. Weatherstripping can prevent warm air from leaking into your home.

9. B. A compact fluorescent bulb lasts longer and emits less heat than an incandescent bulb.

10. True. Always replace the filter cover. The stress of having to cool warm air causes the unit’s efficiency to drop and a loss of effectiveness of the cooling process.

11. False: The thermostat senses the heat produced from the lamp and causes the air conditioner to run longer than necessary.

12. False. The thermostat should increase the temperature setting. Sleep under lightweight bedding and use fans during sleep. You will sleep comfortably with less cooling.

13. B. An air conditioning unit operating in the shade uses 10 percent less energy than one operating in the sun.

14. False. Plug the sink to capture enough water for your shave instead of continuously running the water.

15. C. Water plants or lawn during the earliest and coolest part of the day.

16. A. Instead of pouring pet/aquarium water down the drain, water your plants.

17. C. Repairing household leaks can save more than 11,000 gallons per year or enough to fill a backyard swimming pool!

18. B. Fill a drinking glass with enough water to brush your teeth instead of continuously running the faucet.

19. False. Place sprinklers to only water lawns and gardens instead of the sidewalk or street.

20. False. Setting your thermostat on a colder setting than normal when you turn it on will not cool your home any faster and could result in excessive cooling and, therefore, unnecessary expense.

21. D. All the above is correct. Wise use of hot water and adjusting your water heater temperature can save you money on energy costs.

22. B. Turn off the heater ["hot-dry"] on your dishwasher and let the dishes air dry to save energy.

23. True. Your home will be much hotter inside, using more energy to cool it, if you do heat-producing chores during the hottest times of the day [noon – 5 p.m.].

24. False. Take more showers than baths. Bathing uses the most hot water in the average household.

25. B. Although most water heaters last 10-15 years, it's best to start shopping for a new one if yours is more than 7 years old.

26. True. Unplug battery chargers when the batteries are fully charged or when the chargers are not in use to prevent them from drawing energy.

27. True. Turn off your PC if you are away for 20 minutes or more and turn off both the computer and the monitor if you will be away for two hours or more.

28. A. Over 47 percent of all homes have central cooling.

29. False. It is a better idea to consider the operating cost of the equipment as well as the first cost. Because cooling systems last for many years, the operating cost will greatly exceed the first cost of the equipment over its lifetime.

30. True. A standard single-pane glass provides only a thin barrier to the outside and can account for considerable heat loss and gain.
