Windpower

WindPower is an interactive computer program that can be used to calculate the performance of wind turbines ranging from small domestic units with rotors of a metre or two in diameter up to the largest commercial units with rotor diameters of around 100 metres in diameter.

It can be used for both horizontal axis wind turbines (HAWTs) and vertical axis wind turbines (VAWTs). It calculates mean power and annual energy outputs and enables the economics of a particular turbine to be estimated as a function of the mean wind speed at the site.
