Power Efficiency

Power efficiency refers to how well a device converts electrical energy into useful work or output while minimizing energy loss. It indicates the effectiveness of a system in using the power it consumes, with higher efficiency meaning less energy is wasted as heat or other forms. For example, an energy-efficient appliance provides the same performance as a less efficient one but uses less electricity, saving money and reducing environmental impact. Ultimately, power efficiency helps optimize energy use, making systems perform better while consuming fewer resources.
