The control unit 80 can receive (or supply) electric power, hot water, and exhaust hydrogen from the power distribution network 62, the hot water piping network 64, and the gas piping network 60, respectively.
[0050]
In addition, the control unit 80 may use the electric power and / or the heat medium based on the electric power and / or the heat medium to be generated based on the use state of the electric power and the hot water in the user's house, the power generation and the hot water supply performance of the energy generation device 40, and the like. Is determined to be insufficient or surplus. However, the electric power and / or heat medium to be generated also include electric power and / or heat medium expected to be in demand. For example, when the electric power is used and the hot water is not used, the hot water can be determined to be excessive according to the amount of hot water in the hot water storage tank 26, and the electric power can be determined to be insufficient according to the demand amount. Under the control of the control unit 80, shortage information or surplus information on shortage or surplus of power and / or hot water is transmitted to the server 10 via the communication device 72.

For example, the hard disk 13 stores selection information used to select an energy device that supplies or receives the shortage of power and / or hot water, and the CPU 11 stores the selection information, the shortage information, and the surplus information. , An optimal energy generation device is selected. The selection information includes, for example, information on a positional relationship between the energy generating devices. When there are a plurality of energy generating devices having excess energy, the CPU 11 has a short distance from the energy generating device having insufficient energy. Choose one.

Alternatively, an instruction to receive hot water is transmitted from the communication unit 17. Insufficient information and surplus information corresponding to the transmitted reception instruction and supply instruction are already processed and updated by the CPU 11.
[0055]
Further, the CPU 11 calculates the supply amount of the exhaust hydrogen corresponding to the shortage of the electric power and / or the hot water, and causes the communication unit 17 to transmit the supply instruction and the reception instruction of the exhaust hydrogen based on the calculated supply amount. It is possible to transport the exhaust hydrogen that can be used for generating the electric power and the hot water between the energy generating devices 40 by using the exhaust hydrogen that is easier to handle than the electric power or the hot water.
