1. A method for learning an energy consumption signature associated with a specific appliance from low resolution energy consumption interval data associated with a specific house, comprising:

  • receiving at a processor low-resolution energy consumption interval data corresponding to whole house energy consumption for the specific house, wherein the low-resolution energy consumption interval data is sampled periodically with periods ranging from minute to hourly;

    selectively communicating by the processor with a first database comprising non-electrical information;

    selectively communicating by the processor with a second database comprising training data, the training data comprised at least in part of high resolution energy consumption data received from a plurality of homes associated with appliances at least some of which are the same type as the specific appliance, wherein the high resolution energy consumption data is sampled periodically with periods of less than one minute;

    wherein training data comprises at least in part feedback information by a user through an interactive user interface using interactive charts;

    determining a correlation between the low-resolution energy consumption interval data with a sample of the high resolution training data;

    based on at least in part on the correlation and the non-electrical information, making a determination that the specific appliance was running during the sample of the interval data;

    identifying the energy consumption signature of the specific appliance, at least in part by estimating of the energy consumption by the specific appliance at a hourly, daily or monthly scale; and

    performing an action of energy management by presenting information regarding the energy consumption signature of the specific appliance to a user.
