If you figure how much energy is available at low wind speeds you will realize you can generate so little that it isn't worthwhile. If you make a large enough diameter rotor to start at very low speeds it will be difficult to keep it all together at higher wind speeds. PVs are a better choice if you don't have a 10 to 12 mph annual average wind speed AND a good clear spot for a tower at least 100 feet tall. Anything less is a toy or an experiment.
