Which strategy is utilized to reduce energy usage when a device is inactive?

Power Consumption Modes refer to different operational states that a device can enter based on its activity level, especially when it is not actively in use. These modes are designed to manage energy use by significantly lowering the power requirements of the device when it is inactive. For example, a device may enter a low-power state or standby mode where only essential functions are maintained while most of the system's power-consuming components are turned off or throttled down.

This strategy effectively prolongs battery life in portable devices and reduces overall energy consumption in systems that are frequently inactive. Understanding these modes is crucial in energy management, especially in the context of CPS (Cyber-Physical Systems) where efficient energy use can lead to better performance and sustainability.

While other strategies may contribute to energy savings, Power Consumption Modes are specifically tailored to handle inactivity, making them the most relevant choice for this question.
