Efficiency

Efficiency is the ability to do something well without wasting time, energy, or resources. For example, the efficiency of a washing machine is measured by how much water and energy it uses. A worker who finishes tasks quickly and correctly shows high efficiency. Efficiency is important in daily life, school, work, and technology because it saves time, effort, and money. People often try to improve efficiency by organising, planning, or using better tools. It is the noun form of efficient and tells us about the quality or level of being efficient.
