[Loi] formulée par l'Allemand du même nom en 1919, [déterminant] qu'une éolienne ne pourra jamais convertir en énergie mécanique plus de 16/27 (59 %) de l'énergie cinétique contenue dans le vent. 5, record 1, French, - loi%20de%20Betz

Le coefficient de puissance a été introduit par la théorie de Betz. La limite de Betz indique que, pour les meilleures machines : bipale ou tripale, à axe horizontal, on ne récupère au maximum que 59 % de l'énergie due au vent, ce qui signifie que Cp max (théorique) est environ égal à 0,59. Pour une éolienne de puissance réelle, il est de l'ordre de 0,3 à 0,4 au maximum. 6, record 1, French, - loi%20de%20Betz
