There is no definitive answer to this question as it depends on a variety of factors, including the size and power of the wind turbine, the location of the turbine, the average wind speed in the area, and the specific purpose for which the turbine is being used. Generally speaking, however, a small wind energy system is one that has a capacity of up to 100 kilowatts (kW).

Q: What is considered a small wind turbine?
A: There is no definitive answer to this question as it can vary depending on the specific context in which it is used. In general, however, a small wind turbine is typically any type of wind turbine that has a relatively small physical size and/or power output capacity. This can include both traditional horizontal-axis wind turbines (HAWT) and vertical-axis wind turbines (VAWT), although the latter are often considered to be a separate category due to their different designs. There are also a variety of micro-wind turbines that have even smaller physical footprints and are designed for specific applications such as powering small electronic devices.
Q: What is a small wind speed?
A: There is no definitive answer to this question as wind speeds can vary greatly depending on the location and conditions. However, generally speaking, a small wind speed would be considered to be anything below around 10-15 miles per hour.
Q: How much wind is needed for a small wind turbine?
A: There is no definitive answer to this question as it depends on a number of factors, including the size and type of turbine, the location, and the amount of electricity you wish to generate. Generally speaking, however, you will need an average wind speed of at least 5-6 m/s (11-13 mph) to generate electricity with a small wind turbine.
