About Us

The climate, health, and economic benefits of clean energy are clear, but not everyone has the resources to make the upgrades. Clean Energy Works accelerates inclusive investments that open the clean energy economy to all.

We envision a world with a 100% resilient clean energy economy that provides opportunities and benefits for everyone.

We promote solutions that are inclusive and just.

Racial and social equity are at the heart of our mission. We aim to assure all communities who have been excluded or disproportionately burdened by the energy sector are able to access clean energy upgrades. Clean Energy Works is committed to empowering marginalized communities and communities of color to lead the transition to a clean energy economy.  

We know that change is necessary at the systemic level which is why we champion solutions that can be replicated at scale for transformative impact. We value evidence-based decision making in order to inspire confidence that recommendations will have a high probability of producing targeted outcomes and benefiting everyone.
