About the Organization

The Honnold Foundation envisions a world where marginalized communities lead the transition to renewable energy, with the resources they need to adapt and thrive. We believe in solar as a proven, environmentally sound solution to global energy poverty, and we award grants to community organizations whose projects are innovative, equity-focused, and have the potential to shift the narrative on what’s possible for energy access worldwide.

About the Grant

The Honnold Foundation partners with marginalized communities to expand equitable solar energy access. We believe that solar energy access improves lives and reduces environmental impact, and we provide unrestricted grant funding to organizations across the globe whose work increases social and economic equity in the communities they serve. Though our funds are unrestricted, we tend to select organizations that are directing funds towards a specific project or initiative.

The Honnold Foundation awards funding in two rounds. Round 1 awardees receive their funding in the Spring, and Round 2 awardees receive their funding in the Fall of the same year. Regardless of the timing of their disbursement, all awardees are notified in the Spring.
