In suburban locations, the wind speed is too low and the turbulence is too high for turbines to be cost effective.
There are several designs that claim to be optimised for low speed operation but the fact is that there is very little energy in low wind speeds and no matter what the design it is quite impossible to extract more energy than is actually in the wind.
Moreover it is actually impossible to extract more than 59% of the energy in the wind because it needs some energy to keep moving and come out the other side of the turbine. I have seen claims by manufacturers that show their turbine exceeding this figure, meanng that it is obviously a false claim.
These designs are often include "features" that are supposed to enhance perfomance in turbulence and low wind. In fact the "features" are invariablly associated with low performance efficiency.
Two that particularly come to mind. A spiral vertical axis machine from Europe that is incredibly expensive. The other is built in the US. It has the generator around the outside of the turbine and the most unlikely blade profiles I have every seen in a wnd turbine. This machine is one that publishes impossible performance figures.
BTW I used to work in the industry on design of small wind turbines.
