Disclosed is a total renewable energy system having an underground heat storage device. The disclosed total renewable energy system having an underground heat storage device comprises: a solar collector which is installed on or around a building, and collects and provides solar heat to heat a thermal medium flowing inside a pipeline; a conveying pipe which conveys a high-temperature heat medium, which is supplied from the solar collector, underground; the heat storage device which stores heat through the rise and fall of the heat medium conveyed in the conveying pipe, and heats cold water introduced from the building through a supply pipe and cold air introduced through an inlet duct using the stored heat; a return pipe which returns the heat medium from the heat storage device to the solar collector; an inlet pipe which supplies hot water, which is outputted from the heat storage device, to the building; and a connection duct which supplies warm air, which is outputted from the heat storage device, to the inside of the building. |
