The energy-independent greenhouse according to the present invention is a dual-structure greenhouse composed of a plurality of frame materials and a roof material installed on the ground, a roof material composed of an upper insulating plate and a lower insulating plate, an upper plate water supply portion, a lower plate water supply portion, a lighting portion, An indoor temperature sensor, a heater, a primary circulation water supply pipe connecting the upper plate water supply section and the lower plate water supply section and a circulation collection correction, and a primary circulation water supply pump supplying the water of the circulation collection correction with the primary circulation water supply pipe, the upper portion The primary circulation water supply pipe that returns the primary circulation water, which is water sprayed on the wall and flowed back on the insulation plate and the lower insulation plate, back to the circulation collection correction, and the secondary circulation water supply that moves the primary circulation water returned to the circulation collection correction back to the greenhouse roof Pipe, a secondary circulation water supply pump that supplies primary circulation water to the secondary circulation water supply pipe, a heat pipe that reheats the primary circulation water moved to the greenhouse roof using solar heat, and secondary circulation water, which is water reheated through the heat pipe The second circulation water supply and return pipe to return to the circulating water collection and the upper plate water supply unit, lower plate water supply unit, lighting unit, indoor temperature sensor. It includes a heater, a primary circulation water supply pump and a controller for controlling the secondary circulation water supply pump. According to the energy free-standing greenhouse according to the present invention, there is an advantage that it is possible to solve the heat energy, electricity, and fresh water pro
