Monitoring energy use throughout your whole business is difficult and results in data silos. In today's connected world, the future of energy is inextricably related to IoT. An intelligent Energy Management System (IEMS) is required to help reduce costs, improve efficiency, and satisfy energy needs. Energy management through IoT offers several benefits in handling the smart grids, effective power conservation, increased security and enhanced efficiency. IoT found its applications in Smart Metering, Monitoring Power Usage and in demand forecasting helps in narrowing the energy spending.
