1. A power demand forecast device comprising:
- an absence detection section adapted to detect whether a consumer is absent at a given location;
a power demand forecast section adapted to forecast a power demand on a forecasted date and time in future based on an absence detection result obtained by the absence detection section;
a presence/absence information generation section adapted to generate presence/absence information, wherein if a presence time is greater than a given time threshold, the presence/absence information generation section generates presence/absence information indicating that the consumer is present; and
a power failure determination section adapted to compare a power demand forecast of at least one electric appliance at the current date and time against the present power consumption of the electric appliance and determine whether the electric appliance is developing a power failure based on the difference between the power demand forecast and power consumption and a given threshold.

15. A power demand forecast method comprising:
-
detecting whether a consumer is absent at a given location; forecasting a power demand based on an absence detection result; generating presence/absence information, wherein if a presence time is greater than a given time threshold, the presence/absence information generated indicates that the consumer is present; and comparing a power demand forecast of at least one electric appliance at the current date and time against the present power consumption of the electric appliance and determining whether the electric appliance is developing a power failure based on the difference between the power demand forecast and power consumption and a given threshold.

16. A power demand forecast system comprising:
-
an absence detection section adapted to detect whether a consumer is absent at a given location; a power demand forecast server having a power demand forecast section adapted to forecast a power demand based on an absence detection result obtained by the absence detection section; a communication section adapted to transmit the absence detection result obtained by the absence detection section to the power demand forecast server; a presence/absence information generation section adapted to generate presence/absence information, wherein if a presence time is greater than a given time threshold, the presence/absence information generation section generates presence/absence information indicating that the consumer is present; and a power failure determination section adapted to compare a power demand forecast of at least one electric appliance at the current date and time against the present power consumption of the electric appliance and determine whether the electric appliance is developing a power failure based on the difference between the power demand forecast and power consumption and a given threshold.

17. A power failure detection system comprising:
-
an absence detection section adapted to detect whether a consumer is absent at a given location; a communication section adapted to notify the occurrence of a power failure to external equipment if the power failure determination section determines that a power failure is taking place; a presence/absence information generation section adapted to generate presence/absence information, wherein if a presence time is greater than a given time threshold, the presence/absence information generation section generates presence/absence information indicating that the consumer is present; and a power failure determination section adapted to compare a power demand forecast of at least one electric appliance at the current date and time against the present power consumption of the electric appliance and determine whether the electric appliance is developing a power failure based on the difference between the power demand forecast and power consumption and a given threshold.
