Berkeley Sun Day Event

SunDay is a global day of action on September 21st, 2025, celebrating the unstoppable rise of clean energy.

Berkeley’s Sun Day celebration will be a free, all-ages community gathering at Willard Park’s new LEED-certified clubhouse on September 21st. The event will make clean energy feel local, doable, and joyful by giving residents tangible ways to electrify their homes and lives while celebrating our city’s leadership in the transition. With local partners, hands-on activities, and practical resources, Sun Day will empower Berkeley neighbors to take meaningful climate action together.
