Smart technology contributes to energy efficiency by optimizing how energy is consumed through automation and intelligent monitoring. For example, smart thermostats learn user behavior and adjust heating or cooling based on occupancy and preferences, reducing excess energy usage. Similarly, smart lighting systems can dim or turn off when rooms are unoccupied, minimizing electricity waste. Additionally, smart grids leverage real-time data to improve energy distribution and reduce peak load times. By using data analytics and IoT connectivity, these technologies empower users and organizations to make informed energy management choices, ultimately promoting sustainability.
