Every year, Jewish communities across the globe gather to celebrate Rosh Hashanah and the spiritual “birthday” of our light-filled world. This year, join us to recommit ourselves not only to the renewal of the light within us, but also to a world that values and celebrates sunlight and renewable energy in all its forms!
Sun Day is a national weekend of action that took place on September 21, 2025 to celebrate renewable energy and people power, and stand up to the fossil fuel executives and politicians who are doing everything they can to stop the clean energy transition.
