To complete this assignment, you will need to compute the:

Investment Cost of Measure: Add up the following costs:
- Insulation materials: $550
- Transportation: Six trips of 10 miles round trip per trip at $0.50 per mile
- Labor: 35 hours to transport and install at $25 per hour
- Installation equipment: $20
Annual Energy Savings:
- 5 thousand cubic feet (MCF) of natural gas at $7.66 per MCF
Make the following assumptions:
- Life of Measure is 25 years.
- Energy Price Inflation is 1% annually
- Annual Operating Cost is $0.
- Financing Interest Rate is: 10%

To answer to this question, complete the following:

From the Economics of Energy Efficiency website, report your inputs and the net present value (NPV). If you want, you can save a screen shot of the results and put it into a word file.
Interpret the meaning of the NPV figure computed at the website.
Explain why or why not an investment in home insulation a “wise” economic decision?

(6 pts.) From the November 12^th lecture, discuss your own belief systems in regard to long term perspectives related to sustainability. What belief system(s) do you think best describe your own value system? Give examples of how your behaviors correspond to these belief systems.
