Articles on Small & Household Size Wind Turbines

Small wind turbines encompass a broad range of wind turbines from micro turbines, to mini turbines, to household-size turbines. Wind turbines in these size classes may have power ratings from a few watts to dozens of kW. Internationally, this category includes wind turbines up to 15 meters (49 feet) in diameter. Wind turbines of this size may have power ratings from 50 to 100 kW.

While ducted or shrouded wind turbines and Vertical Axis Wind Turbines can be of any size, they are listed here because they are outside the mainstream of the commercial wind industry.
