Wind Rose
Before efficient wind energy development can occur, the actual wind speed at a location must be known. This need to accurately know the wind speed is because wind power production is a cubic function of the wind speed (wind speed raised to the third power). Thus a 10% increase in the wind speed will increase power production by 30%.
What is a WIND ROSE?
A circular diagram showing, for a specific location, the percentage of the time the wind is from each compass direction.
Below is a picture of a Wind Rose created for the Scottsbluff Nebraska area.
