In the facile of acute energy crises in several countries, conservation of energy becomes a critical factor. The work in this paper describes available method for conservation of energy. It also describes the implemented results of a field demonstration that also online monitor the usage and generation of electricity. The technique was amply demonstrated in our labs and classrooms. ZigBee Module is developed by Jennic and was used because of its wide range, very low power consumption and complexity. After implementation of this system it successfully conserved and controlled the billing and save about 30% of electricity of the department. The system also provided a wireless system with supplies and generators, thus saving a messy network of wires.
