SunDay is a global day of action on September 21st, 2025, celebrating the unstoppable rise of clean energy. We’ll come together to showcase the power of the sun and wind, the energy sources that can power our world without pollution.

Join us in Laramie along with the Alliance for Renewable Energy, UW Sustainability Coalition, City of Laramie, Sierra Club, and other community partners to talk about solar power, participate in art activities, and learn how you can support Wyoming's clean energy future.
