Small wind turbine

<p>Small wind turbines, also known as micro wind turbines or urban wind turbines, are <a href="/facts/Wind_turbine/lUfWqfLg">wind turbines</a> that generate electricity for <a href="/facts/Microgeneration/e7WqUscC">small-scale use</a>. These turbines are typically smaller than those found in <a href="/facts/Wind_farms/geQfaAFu">wind farms</a>. Small wind turbines often have passive <a href="/facts/Yaw_system/lbfITA0o">yaw systems</a> as opposed to active ones. They use a <a href="/facts/Direct-drive_mechanism/wrFGyqWt">direct drive</a> generator and use a tail fin to point into the wind, whereas larger turbines have <a href="/facts/Gearbox/eoNqAufN">geared</a> <a href="/facts/Powertrain/LhPy4KGC">powertrains</a> that are actively pointed into the wind.
</p><p>They usually produce between 500 W and 10 kW, with some as small as 50 W. The Canadian Wind Energy Association considers small wind turbines to be up to 300 kW, while the <a href="/facts/IEC_61400/A7K6JAdd">IEC 61400</a> standard defines them as having a rotor area smaller than 200 m2 and generating voltage below 1000 Va.c. or 1500 Vd.c.
