Abstract

Sensors are provided with information transmission units for transmitting power information to a mobile information terminal and a server. The server is provided with a server storage unit that stores power information for the duration of a second period. The mobile information terminal is provided with: a terminal storage unit that stores power information for the duration of a first period that is shorter than the second period; a power information acquisition unit that acquires power information from the terminal storage unit or the server, in accordance with a display period specified by a user; and a display control unit that displays the acquired power information.
