Third Act's Sun Day Fundraising Drive

We’re raising $150,000 to help launch Sun Day—a nationwide day of action and celebration for clean energy on September 21, 2025.

From rallies and performances to teach-ins and community projects, Sun Day will spotlight the power of solar and wind—and call for a fast, fair transition away from fossil fuels.

Solar is the cheapest energy on Earth, but fossil fuel billionaires are doing everything they can to block it. Let’s show what’s possible when we come together.
