This review focuses on the water evaporation‐induced electricity generation (WEG), a promising renewable energy technology that harvests through interfacial interactions during water's liquid‐to‐vapor phase transition. The article outlines fundamental mechanisms of streaming potential and evaporation potential, along with multiple optimization strategies, e.g., material surface modification, preparation hybrid composites, construction nanochannels, adjustment wetting interface, bio‐inspired designs. Furthermore, explores practical applications WEG in fields such as power supply, environmental monitoring sensors, integrated desalination systems. Finally, highlights future research directions, emphasizing enhanced conversion efficiency, optimizing designs, scalable application development, which is expected to make an important alternative source regions rich resources solar energy.
