The low energy of compensatory atmospheric movements near the surface and its pronounced increase with height dictate wind turbine systems of a size greater than any previously planned. Independent of the basic principle suggested, the most effective method of minimising the total expenditure is to use the highest possible specific speed. In cases where wind energy systems supply an appropriate amount of power to a grid, the analysis of the discrepancy between the momentary power available and the momentary demand has, assuming large-scale sepa­ ration of the wind turbines in available areas, shown surprisingly good results. The complementary use of solar and wind energy systems, taking into consideration global climatic data, also seems very promising. La faible densite d’energie developpee par les mouvements atmospheriques a proximite du sol et son augmentation sensible au fur et a mesure de l’accroissement de la hauteur font songer ades grandeurs systematiques pour turbines avent, qui depassent largement tout ce qu’on pouvait s’imaginer jusqu’a present dans cet ordre d’idee. 11 s’avere alors parfaitement possible­ quelle que soit la conception de base proposee - de prevoir une vitesse de rotation specifique en vue de minimiser l’ensemble des depenses. L’analyse de la discrepance entre ce qui est propose momentanement et les besoins effectifs, en regard de la proportion de puissance fuornie par des systemes energetiques utilisant la force du vent reellement installee dans les reseaux electriques, a donne des resultats favorables surprenants pour une certaine repartition des turbines a vent dans de grands espaces dis­ ponibles.
