Thermochromic (TC) windows with passively controlled sunlight regulation have demonstrated significant building energy conservations. Realizing the active control of TC window can expand its popularity while remaining an intractable challenge. Herein, a low-power-dissipative strategy that endows actively tunable transmittance is presented through electro-induced photothermal conversions (ETPCs). Through diverse variations at different voltages, be selectively transformed to desired temperatures. After integration hydrogel, thermochromism optionally accelerated or turned off in weather conditions. The fabricated smart realize high optical modulation (ΔT500 nm = 85.13%) lower indoor temperature by 26.2 °C low-energy consumption (lower than 10.5 μW·cm–2). Compared normal windows, as-fabricated cut 20.1% consumption, demonstrating huge potential combat global climate change.
