Our Team

We are community energy enthusiasts who see energy efficiency and community-controlled clean energy as the first step toward relocalizing our economy. We have created CEF to support our communities in the process of building people-powered solutions to the energy crisis and climate change.

Cooperative Energy Futures is comprised of a Board of Directors and a staff team that handles the day-to-day operations of the cooperative. We rely heavily on grassroots leadership by current and potential members and community partners. We welcome volunteers; if you are interested in joining us, check out our Get Involved page.
