Since there are many renewable energy alternatives available to homeowners to help their house become more eco- friendly, especially in Pacific Northwest area. This project will help them analyze what alternative is suitable for their house and worth for investment. In the research, we have identified three technologies which are solar power, wind power, and geothermal power and they will be virtually applied to one of our member’s house which located in Portland metropolitan area. This project will analyze the financial feasibility for each alternative by applying NPV, IRR, incremental IRR, and Benefit -Cost analysis techniques in order to obtain the best alternative. The alternative’s information has been gathered by literature reviews on costs and benefits such as installation and maintenance costs, energy saving cost, and incentives for each technology. Besides the sensitivity analysis is conducted in order to investigate uncertain variables that have an influence on the research results
