Height advantage

Definition

Height advantage refers to the increased effectiveness and efficiency in energy generation that occurs at greater altitudes where wind speeds tend to be higher and more consistent. This concept is essential in understanding how airborne wind energy systems can capture more kinetic energy from the wind, leading to improved aerodynamic efficiency and greater power generation potential.
