This June, Mammoth - A Climate Action Cinema is joining the Great Big Green Week 2026 and celebrating its third birthday with a whole week of screenings!

Two artists in Walthamstow set out to take their street off the grid, kickstarting a solar-powered energy revolution.

Inspired by lockdown mutual aid initiatives, artist-activists Hilary Powell and Dan Edelstyn decided to turn their street into an energy-generating powerhouse – a prototype for a new way of living, with the hope of galvanising a wider push towards sustainable alternatives. Directed by the duo, POWER STATION charts their turbulent journey, from pitching the idea to their neighbours and sleeping on the roof of their home to raising finance and launching a bid for a Christmas number one single. By turns funny and heartwarming, Powell and Edelstyn’s film is a vibrant portrait of their local neighbourhood, and a charming testament to the power of art in changing minds about what could be possible.
