HOW THE CHINESE HEAT A GREENHOUSE WITHOUT GAS or ELECTRICITY

HOW THE CHINESE HEAT A GREENHOUSE WITHOUT GAS or ELECTRICITY. How can a greenhouse stay warm through winter without using gas or electricity? In rural China, farmers have been doing it for decades with simple materials and clever design. This video explores how Chinese greenhouses stay warm off-grid, combining ancient knowledge with practical innovation. You’ll see how thick earthen walls, solar heat storage, straw insulation, and smart ventilation create a steady indoor climate even in freezing temperatures. The system collects sunlight during the day and slowly releases warmth at night, protecting crops and saving energy. This approach shows how sustainability can come from tradition, not technology. It continues to support farmers across the country while reducing costs and environmental impact.
