1. Wind Turbine Survey

The picture below is a 2.4kW wind turbine installed in the backyard of a Mission District home in SF. It generates on average 400 kWh of power a month. A standard 3 bedroom house in SF typically will not use more than 400 kWh of electricity in summer. The installed cost of this system roughly costs $28,000 before incentives. With Federal and State incentives, you may only need to pay 50% of the cost. Depending on where your house is located, the same turbine will have slightly different performance.


* 1. Do you think it is a good idea to independently generate power for your own use?

* 2. What is your monthly electricity bill in summer and winter? Where is your house located?

* 3. Your interest in a renewable energy is due to its promise of ____________. Please rank these reasons from 1 (most important) to 5 (least important).

  Most Important Important Least Important
Environmental protection
Reduction in energy use
Low carbon footprint
Increase of property value
Personal interest

* 4. How interested are you in considering wind as your choice to power your home?

  Not interested at all Somewhat interested Interested Very Interested
Interest Level

* 5. Please evaluate each reason for NOT installing a wind turbine. Base your answers on a scale of 1-5. 1 being MAJOR reason NOT to install, 5 being MINOR reason NOT to install.

  Major Reason NOT to Install Minor Reason NOT to Install
Safety concerns
Structural concerns
Neighborhood concerns
Aesthetics of turbines
Low power production
Danger for birds
Permitting process
Product reliability
Not enough wind

* 6. What federal and state incentives are you aware of that are available for small wind installation?

* 7. Were you aware that there is plenty of wind in the Bay Area and in some areas a small wind system performs better than solar panels?

* 8. Many people use payback time period (the period of time it takes to recover your original investment) to evaluate their reason for investing in renewable energies. For example, if you paid $20,000 for a wind turbine, and you are saving $100/month on your electricity bill, it will take you 192 months (16 years) to recover your initial investment. Do you think this is reasonable investment?

* 9. What concerns, if any, do you have if many urban residents install the wind systems in their backyard or rooftop?
