Treehugger.com has lots of articles about solar and wind projects. One is the storm blade turbine. It is quiet and would work residentially. Go to stormbladeturbine.com to see it.
Also there is another project that is residential that is totally quiet and makes 20kW. It is sort of tall and would need a larger lot to be approved in most places. I thought you’d like this story from TreeHugger: 30-Blade Eco Whisper Wind Turbine is “Virtually Silent”.
