USE - Used as a renewable energy utilization device.    ADVANTAGE - The renewable energy utilization device is simple and cost effective.    DETAILED DESCRIPTION - The renewable energy utilization device comprises a sea water desalting chamber (6). A top part the sea water desalting chamber is divided into an evaporation chamber (7) and a condensation chamber (11). A baffle plate is provided a seawater inlet pipe. The evaporating chamber is equipped with a radiating pipe. A water inlet and a water outlet of the radiating pipe are connected with a solar heat collecting system (9). A water outlet and inlet holes of the solar heat collecting system are connected with the evaporating chamber provided with an electric heater (10). The electric heater is connected with a storage battery. The storage battery is fixed with a wind energy generating system, a wave energy generating system or a marine tidal power generating system and electrically connected with a control system. An upper part of the evaporation chamber is connected with an air pump. The condensation chamber is provided with a condensing pipe, a pre-heating pipe of a heat pump unit and an evaporation chamber heat recycling and circulating system. A lower part of the evaporation chamber is provided with a thick water outlet pipe connected with a lower cavity of a condensing room. A control circuit is connected with the electric heater.
