Abstract Water evaporation–induced electricity generators (WEGs) are regarded as one of the most promising solutions for addressing increasingly severe environmental pollution and energy crisis. Owing to potential carbon emission in preparation process WEGs, whether WEG represents a clean generation technology is open question. Here, brand‐new strategy proposed manufacturing negative (CWEG). In this strategy, microalgae film used interface WEG, which achieves stable open‐circuit voltage (V oc ) 0.25 V short‐circuit current (I sc 3.3 µA. Since can capture dioxide during its growing process, CWEG holds great promise generate without emissions full life cycle compared with other WEGs. To best author's knowledge, first work using films fabricate WEG. Therefore, it believed that not only provides new direction designing high‐efficiency eco‐friendly but also offers an innovative approach resource utilization microalgae.
