SUN DAY

Berkeley’s Sun Day celebration is a free, all-ages community gathering at Willard Park’s new LEED-certified clubhouse on September 21st. The event will make clean energy progress local, doable, and joyful by giving residents tangible ways to electrify their homes. We will also learn about Berkeley's beacon leadership in implementing over 25 clean energy municipal projects. With local partners, hands-on activities, and practical resources, Sun Day empowers Berkeley residents to take meaningful action together to combat the climate crisis.
