System efficiency

Definition

System efficiency refers to the ratio of useful output to the total input in a system, often expressed as a percentage. This concept is crucial for understanding how effectively energy is converted and utilized within various systems, particularly in hybrid systems that combine different energy sources to optimize performance and minimize waste. Improved system efficiency can lead to lower operational costs, enhanced sustainability, and better integration of complementary energy sources.
