A micro wind turbine is simply a small wind turbine that generates small amounts of electricity (usually under one kilowatt and sometimes as low as 50 watts) from wind energy. Micro wind turbines contrast with the larger wind turbines that are used on wind farms to generate power on a commercial scale. Micro wind turbines are often used on boats or other vehicles to power small appliances such as lights or a refrigeration unit.
The weight of a micro wind turbine designed for home use can be as little as 35 pounds. This makes the turbine sensitive to minor wind movements and more useful in urban areas where winds are subject to being interrupted and intermittent.
