Smart home technology enhances energy efficiency by integrating automated systems that monitor and control energy consumption. Devices like smart thermostats, lighting, and appliances can adjust usage based on user behavior and preferences. For instance, smart thermostats learn a household's routine and optimize heating and cooling schedules, reducing energy waste. Additionally, homeowners can remotely manage these systems through smartphones, allowing for real-time adjustments and monitoring. This automation not only lowers energy bills but also contributes to reducing overall carbon emissions, supporting environmental sustainability.
