Once the wind turbine is up and running there are few running costs Wind is also an infinite resource that cannot be exhausted.Ī small home wind turbine – when installed in the right location – can cut your reliance on traditional fossil fuel resources. To get the most accurate picture, you should run the anemometer for a minimum of three months, and ideally over the course of a year.Įlectricity generated by the wind does not emit CO2 or leave any waste. However, before making any significant investment in a wind turbine it is recommended that you invest in an anemometer to measure the average wind speed at your proposed location. Turbines sited in urban areas are unlikely to perform well and locations such as the bottom of rural valleys are also probably unsuitable. An ideal location will have no significant obstructions such as tall buildings that are likely to either reduce wind speed or create a turbulent airflow. There are a number of factors that can affect wind speed such as nearby buildings, trees and the height of the turbine from the ground. The Average wind speed is a key factor to consider for any wind turbine installation and the recommended annual average wind speed for a location is 6 metres per second (13 mph). The turbine does not have to directly face the wind in order to rotate and is considered by manufacturers to be more suited to areas where the wind is turbulent. This type of turbine has the main rotor shaft running down vertically which allows them to have the gearbox located at the base of the turbine. The towers that support this design need to have strong foundations in order to prevent the turbine from blowing over and on domestic systems they will often have guy wires to provide additional support. They have turbine blades that look like an aeroplane propeller. There are two main designs of turbine, vertical axis and horizontal axis. Domestic wind turbines generally range from between 1kW to 6kW and will be either building mounted or free-standing depending on their size.
