Disclosed herein is a hybrid renewable energy system having an underground heat storage apparatus. A solar collector is provided on or around a building structure and collects solar heat to heat a heat medium. A transfer pipe transfers the heat medium, heated by the solar collector, into the underground. The heat storage apparatus stores heat received from the heat medium and heats, using the stored heat, both cold water supplied from the building structure through a supply pipe and air supplied from an inlet duct. A return pipe returns the heat medium from the heat storage apparatus to the solar collector. An inlet pipe supplies hot water produced by the heat storage apparatus to the building structure. A connection duct supplies air heated by the heat storage apparatus into the building structure to heat the room of the building structure.
