In the contemporary period, the most important element in sustaining and developing the society, under all its aspects, is represented by energy. Due to the fact that in society consumption is increasing, the actual concern is to reduce the energy consumption and also to find green, alternative sources to produce energy. The theme of this article is directed towards the concepts of increased availability and energetic independency and concerns estimations over the wind potential in certain areas of lower Prut river basin. In order to get an outcome, there were analyzed genetic factors of the wind important parameters of wind speed, useful to the justification of the wind potential study. Increased wind speed in the meaning of what was stated, was approved only on high valleys and upper terraces in the main valleys, especially on the Prut valley.
