5. Wind Speed vs. Wind Power Density Wind speed alone may not be a reliable indicator of the annual average wind power density. Actual wind power density, which is based on the frequency distribution of the wind speeds, can be substantially different for the locations with the same measured wind speed, such that each location has a different wind power class.
