An energy efficiency quiz!

The 2012 Ms. Green Energy Quiz – Do you know your energy efficiency facts?

Readers,

Ms. Green feels like she’s always hammering you over the head with the same basic information about energy efficiency, and yet she is worried that while many of you nod your heads when reading her informed and charming responses to the many questions offered to her in this column, that you have not yet internalized the truth about how best to live lives of complete energy efficiency, saving yourself money whilst saving the world at the same time.

10. What part of the average central NC home typically leaks 30% of conditioned air?

d) electrical outlets

 

Answers:

1. c. Home heating and cooling has the biggest effect on the average American’s carbon footprint over his or her lifetime. If you ask Ms. Green, becoming more energy efficient is the single most important thing we should do as a nation to become less dependent on foreign oil and more sustainable as a country.

2.  c. Air leaks are the primary reason for loss of conditioned air. Leaks in the attic and the crawl space, as well as leaks in the air ducts, have the biggest impact on heating and cooling bills. Windows can be leaky, but typically leaks from windows aren’t as big a deal as those in other parts of the house, plus, windows are very expensive to replace. Sealing air leaks in the attic, crawl, or air ducts is one of the least expensive and most effective energy efficiency changes you can make in your home.

3. d. Why are we even considering building new nuclear power (or coal, or whatever) plants when we can weatherize and get far more benefit? See energysavvy.com for details.

4. d. If we need jobs in this country, we should weatherize. ‘Nuff said. See energy savvy.com for details.

5. e. Ms. Green can’t say it enough: weatherizing existing housing stock is THE ANSWER to this country’s energy crisis, plus it creates jobs, plus it puts more money in everyone’s pocket.

6. d. Ms. Green told you that replacing your windows gives you poor return on your investment.

7. a or b, depending on your existing windows, how many windows you have, and whether or not you install the storms yourself.

8. d. Caulk seals air leaks. Air leaks = energy leaks. Energy leaks = wasting money. Therefore caulking air leaks = saving big money.

9. c. Fixing low hanging fruit is a great first step, but then you need to do a, b, and d to see true energy savings.

10. b. Ouch. Sealing your ductwork is a very important part of becoming more energy efficient.
