Wind power is viewed as the most economical renewable energy technology as well as having the quickest investment return rate. Most modern wind power is generated in the form of electricity by converting the rotation of turbine blades into electrical current by means of an electrical generator.

Wind turbines are best located on sites in coastal areas, on graduated topography and on open plains where wind is strong and reliable. The current wind power technology requires an average wind speed of around 25 km/h, to be economically viable.

Small wind generation systems with capacities of 100 kW or less are can be used to provide electrical energy for schools. However a site assessment is essential before a wind turbine should be considered to determine whether the average annual wind speed is sufficiently high enough to provide the required yield.

Two types of wind turbine are appropriate for use in schools – free standing and building mounted which can be on a vertical or horizontal axis. Wind speeds of at least 4.5m/s for building mounted and 5m/s for free standing turbine are required.
Capital costs can be high due to construction and installation costs but running costs are low once installed.
