Sun Day is a day of action on September 21, 2025, celebrating the power of clean energy. On this day, we’ll celebrate the progress we’ve made and push for more. We’ll install new solar, host e-bike parades, give heat pump tours, and rally for change. Together, we’ll make the sun rise on our clean energy future.

Sun DAY NYC will feature a Power UP: Speaking Solar Panel moderated by Kai Wright and featuring Bill McKibben, Brad Lander, Sany Nurse and others. There will be a Family Friendly Renewable Energy Fair full of information booths and tables, and kid-friendly activities. A performance for children by Esther Crow and a closing performance by Reverend Billy and the Stop Shopping Choir.
