ABSTRACT
General wind power or area was determined from available wind speed data and then wind maps were developed. In general, the available wind speed data covered heights of 6 to 20 m; however, some anemometers were on tops of buildings or control towers at airports and their heights influenced the accuracy of the data. In many parts of the world, the amount of wind speed data was limited to daily or even monthly averages. Wind classes were developed for 10 m height, because that is the standard for world meteorological data. The wind power potential at 50 m was double that at 10 m due to the assumption that the wind shear exponent was 1/7 for all locations.
