The people on our globe have limited ability to take use of the advantages provided by our abundant renewable and conventional energy resources owing to a lack of technical skills and capability, as well as the need for water-energy resources. The use of Internet of Things (IoT) technology, together with advanced IoT sensing and communications techniques, has the capacity to revolutionize the sustainable energy industry via research and innovation. The use of existing infrastructure, including green technologies, microgrids, and hydrogen gas derived from power infrastructure, may enhance the role of the IoT in sustainable energy. This, in turn, can bolster community energy security while minimizing any adverse environmental and cultural impacts. This research introduces the fundamental ideas, approach, potential situations, and instruments for implementing the IoT in sustainable energy systems. Furthermore, a comprehensive examination of diverse sensing and messaging tactics is included. The use of IoT in the grid is expected to enhance system flexibility, ensure reliable data flow and connection. This application of IoT in sustainable energy is predicted to enhance the intersection of network services in the grid. The objective will be achieved by using IoT technology in the grid system. Furthermore, this research emphasizes the challenges associated with doing research on sustainable energy utilizing IoT technology, as well as the potential for innovation. These endeavours strive to tackle the intricate energy requirements of our society and foster the growth of a robust economy in the energy industry.
