The development in digital technologies possess immense opportunity in addressing various social and related aspects. It has been noted that the energy consumption is expected to increase manifolds in the next two decades and there is a growing concern to meet the energy needs in a sustainable manner. The IoT enable in supporting the energy companies, government, business and individuals in enhancing the energy consumption, optimally use the resources in an effective manner and thereby reduce the emission of greenhouse gases. Hence the increasing complexities of the traditional power grids does not able to support the growing energy needs and though application of IoT power grids can support in enhancing the communication, achieve greater efficiency in power consumption and possess great integration between different sources of power generation. The use of smart networks enables better demand management, bidirectional interaction, and thus meets users' needs and requirements. Implementing IoT can also help manage the integration of electricity consumption in a sustainable way. IoT-based smart grids can help reduce stress during rush hour. greenhouse gases
