Final answer:
The energy sector utilizes IoT technologies for smart grid deployment, enhancing efficiency in electricity distribution. Although smart grids are significant in this sector, overall in a postindustrial society, information is considered the most important commodity.
Step-by-step explanation:
The industry sector that uses IoT (Internet of Things) technologies to deploy smart grids is energy. Smart grids are electrical supply networks that use digital communications technology to detect and react to local changes in usage, improving efficiency and reliability of electricity distribution.
The integration of IoT in smart grids allows for real-time data collection, analytics, and management of electrical resources. Meanwhile, the most important commodity in a postindustrial society is generally considered to be information. In such societies, the ability to process, store, and disseminate information becomes a critical driver of economic and social development.
