System to make consumers aware of electricity usage
Energy usage of a plurality of appliances is measured using a single meter. A pattern of energy usage with respect to the plurality of appliances is determined dependent upon the measured energy usage, appliance details of the plurality of appliances, and usage hours of the plurality of appliances. The pattern is provided to a user of the appliances.
1. An energy usage awareness method comprising:
measuring combined energy usage of a plurality of appliances within a building using a single meter;
retrieving appliance information from a memory, the appliance information comprising information about the types of appliances installed within the building, the number of appliances of each type installed within the building, ratings information of each of the appliances, and a listing of typical usage hours of each appliance;
inferring a pattern of energy usage for each appliance using the measured energy usage, the appliance information, and the listing of typical usage hours of each appliance type; and,
providing the pattern of energy usage to a user of the appliances.
2. The method of claim 1 wherein the step of providing the pattern to a user of the appliances comprises displaying the pattern on a display.
3. The method of claim 1 wherein the step of providing the pattern to a user of the appliances comprises displaying the pattern on a display that is located so as to be viewable by the user and that is located remotely from the single meter.
4. The method of claim 1 wherein the step of measuring energy usage comprises measuring the energy usage at a point that is between a tariff meter and the appliances.
5. The method of claim 4 wherein the step of providing the pattern to a user of the appliances comprises displaying the pattern on a display.
6. The method of claim 4 wherein the step of providing the pattern to a user of the appliances comprises displaying the pattern on a display that is located so as to be viewable by the user and that is located remotely from the single meter.
7. The method of claim 1 wherein the step of measuring energy usage of a plurality of appliances using a single meter comprises communicating the measured energy usage to a processor, and wherein the determining of a pattern of energy usage comprises determining the pattern of energy usage by use of the processor.
8. The method of claim 7 wherein the step of communicating the measured energy usage to a processor comprises communicating the measured energy usage to the processor over a wire link.
9. The method of claim 7 wherein the step of communicating the measured energy usage to a processor comprises communicating the measured energy usage to the processor over a wireless link.
