SOLUTION: Electric power and heat are generated by a fuel cell 11 using fuel gas, and the hot water, made by heating city water by the heat generated by the fuel cell, is stocked in a hot water tank 13, and supplied to the bath or the like. The generated energy volume is measured by a hot water supply energy meter 14 and an electricity volume meter 15, and the consumption volume of fuel gas, city water, and electric power at home are measured by a gas meter 16, a water meter 17, and an electric power meter 18. Respective generation volume and used volume are transmitted to a control center 20 through a communication device 12. Addition to respective generation volume and used volume, respective costs are displayed at the displaying device 19, therefore, household energy saving property and cost effect are enabled to judge. |
