Provided that favorable wind resources are in place, small wind turbines can deliver considerable benefits for individuals or small communities; relatively easy to build, they can deliver important amounts of energy which can be used for a large variety of applications, from battery charging to powering equipment. Compared to PV (Photovoltaic) panels, they operate also during the night and in winter, when the sun is weaker in many regions of the world. Additionally, they do not require an inverter, since the electricity delivered is already DC. |
Difficult to estimate, since it depends a lot on the weather conditions where the wind turbine is installed; however, once installed in the correct location, the wind turbine can deliver electricity for several years. |
An average cost of 200 to 1,000 Euro should be expected when using quality components, but the final cost can be lowered if recycled materials are used. Additionally, cheaper solutions can be found online, but the quality of the product deliver is not always matching the requirements.

If built correctly, the small wind turbine should last a minimum of 15-20 years. |

Wood, steel, copper wires, magnets, bearings, epoxy resin (or equivalent). |
Although the construction can be done by anyone, a certain knowledge of handling tools is required. Furthermore, some countries might need to install the turbine on a high tower due to limited wind resources. |

The installation and usage of a wind turbine means that electricity can be produced freely for the whole lifetime of the turbine. This means that less or no diesel generators should be used, resulting in a considerable reduction in emissions.
