The conversion, storage, and utilization of renewable energy have all become more important than ever before as a response to ever‐growing energy and environment concerns. The performance of energy‐related technologies strongly relies on the structure and property of the material used. The earth‐abundant family of tungsten oxides (WO x ≤3 ) receives considerable attention in photocatalysis, electrochemistry, and phototherapy due to their highly tunable structures and unique physicochemical properties. Great breakthroughs have been made in enhancing the optical absorption, charge separation, redox capability, and electrical conductivity of WO x ≤3 through control of the composition, crystal structure, morphology, and construction of composite structures with other materials, which significantly promotes the efficiency of processes and devices based on this material. Herein, the properties and synthesis of WO x ≤3 family are reviewed, and then their energy‐related applications are highlighted, including solar‐light‐driven water splitting, CO 2 reduction, and pollutant removal, electrochromism, supercapacitors, lithium batteries, solar and fuel cells, non‐volatile memory devices, gas sensors, and cancer therapy, from the aspect of function‐oriented structure design and control.
