Given how commonplace it is in today’s economy, where are our great films about solar power? I’m not thinking here of those countless disaster and science fiction films that feature a dying sun or volatile solar winds as catalysts for global catastrophe, but simply movies that would give life to the otherwise unremarkable solar panels tilted skyward on roofs and farms around the world. In recent memory, a film like the Dardenne brothers’ Two Days, One Night (2014) might be the only one that fits the bill. There, Marion Cotillard plays Sandra, a worker at a Belgian solar panel factory who is forced to plead with her colleagues so that she can keep her job after a leave of absence; the energy may be clean, but the company’s politics are dirty.
