From the wind speed data recorded over 9 (1990-1998) and 10 (1990-1999) years, as observed in the main meteorological stations, called synoptical stations, of the observation network of the National Meteorology Department, located in the Adamaoua and Northern Cameroon provinces, an estimation of the wind energy available has been made for each station. For this use, the wind speed frequencies in the period are considered. Daily, monthly and annual mean wind speeds and wind energy available were determined. The possible applications of this energy for each station are discussed.
