Conversion efficiency

Definition

Conversion efficiency refers to the ratio of useful energy output from a system to the total energy input into that system, expressed as a percentage. High conversion efficiency indicates that a larger portion of the input energy is being transformed into usable output energy, which is particularly crucial in optimizing energy systems like those harnessing tidal and wave energy. Understanding conversion efficiency helps in evaluating the effectiveness of different technologies and systems designed for energy capture and utilization.
