Bill McKibben and Third Act! are kicking off the next phase of the renewable revolution: Sun Day is a global day of action to support solar energy and climate justice. 350 Mass is excited to join in all the fun.
From the Sun Day website:
Sun Day is a day of action on September 21, 2025, celebrating the power of clean energy.
The clean energy revolution is here. Solar, wind and batteries are the cheapest form of power on the planet, lowering costs, creating new jobs, and strengthening our communities. But some politicians and industries are trying to hold it back.
On Sep 21, 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.
