Planet Sun is a feature documentary that follows Australian renewable energy pioneer Andy Evans on a sweeping journey across ten countries to explore the sun as both a physical force and a cultural idea—shaping civilisation, science, and survival. Moving from ancient solar sites such as Teotihuacán and Chichén Itzá in Mexico to Stonehenge in the UK and Newgrange in Ireland, and onward to modern feats of engineering like Ivanpah in the Mojave Desert, the film connects deep human history with the present-tense reality of the energy transition. Guided by director Dominic Allen, Planet Sun blends travelogue, lived encounters, and expert insight into an accessible, cinematic work about how we’ve revered, depended on, and learned to harness the star that sustains us all.
