The technology that helps reduce energy consumption in smart devices is known as Energy-Efficient Computing. This includes various approaches such as low-power hardware, smart sensors, and energy management algorithms that optimize power usage. Innovations like dyanmic voltage and frequency scaling allow devices to adjust their power needs based on workload. Furthermore, smart home systems can automate energy usage, turning off devices when not in use and optimizing settings for efficiency. These technologies not only contribute to reduced energy bills but also promote environmental sustainability.
