The illustrative embodiment describes a system that manages the energy usage of a user's appliance based on: (i) the user's location, and (ii) the user's“presence information.”The“presence information”of a user is defined as a status indicator that includes, but is not limited to: the ability and willingness of a user to communicate and a user's mood. For example, when a user is lonely and at work, the office door should open, but when the user is not lonely and at work, the user's instant messages should be shut off. The illustrative embodiment comprises: an appliance; and an energy-usage controller for de-activating an energy-consuming element of the appliance based on presence information of a user of the appliance.
