Efficiency

Definition

Efficiency refers to the ratio of useful output to the total input in a system, reflecting how well energy or resources are converted into desired work or results. In the context of energy systems, higher efficiency means less waste and more effective utilization of available energy, which is crucial for optimizing performance across various methods of power generation, energy yield predictions, energy storage technologies, and the fundamental principles of airborne wind energy systems.
