Turbine blades for small-scale wind turbines are typically 1.5 to 3.5 metres (4 ft 11 in – 11 ft 6 in) in diameter and produce 0.5-10 kW at their optimal wind speed. [1] Most small wind turbines are horizontal-axis wind turbines , [ 2 ] but vertical axis wind turbines (VAWTs) may have benefits in maintenance and placement, although they are ...
The main cost of small wind turbines is the purchase and installation process, which averages between $48,000 and $65,000 per installation. Usually, the total amount of energy harvested amount to more than the cost of the turbines. [117]

Small wind turbines are defined as being of up to 200 m 2 swept area and a somewhat simplified IEC 61400-2 standard addresses these. It is also possible to use the IEC 61400-1 standard for turbines of less than 200 m 2 swept area. The standards for loads and noise are used in the development of prototypes at the Østerild Wind Turbine Test ...
Bergey Windpower, a leading manufacturer of small wind turbines is located in Oklahoma. Programs leading to careers in the wind power industry are provided at tech schools, community colleges and universities in Oklahoma. The Oklahoma Wind Power Initiative supports the development of wind power in the state. [73]
All the most powerful turbines are offshore wind turbines. This list also includes the most powerful onshore wind turbines, although they are relatively small compared to the largest offshore ones. As of June 2024, the most powerful wind turbine in operation is the world's first 18MW semi-direct drive offshore wind turbine, developed by ...
