Claim:
1. An electrical appliance comprising: a communicator to receive energy related information from an energy grid; a controller to receive the energy related information from the communicator; an energy consumption component operated by the controller; and an input to receive a command to select an operation mode of the energy consumption component, wherein the operation mode of the energy consumption component comprises: a first power saving mode in which the operation of the energy consumption component is restricted on a basis of the energy related information, and a second power saying mode in which the operation of the energy consumption component is restricted irrespective of the energy related information, and wherein one of the first and second power saving modes is selected through the input, wherein the energy related information comprises a restriction time period, the controller selects one of a delay appliance load mode and a temporary appliance load reduction mode of the appliance on a basis of a length of the restriction time period, wherein in the delay appliance load mode: the controller stops a defrosting cycle of the appliance in the restriction time period and starts the defrosting cycle again from the beginning of the defrosting cycle after the restriction time period ends; wherein in the temporary appliance load reduction mode: the controller stops the defrosting cycle of the appliance in the restriction time period and resumes the defrosting cycle from where the defrosting cycle was stopped after the restriction time period ends.
