making energy missional

our purpose

EFM exists to empower mission among the most vulnerable through promoting energy efficiency and clean, renewable energy.

While energy is part of our expertise, we pursue partnership in any initiative – whether microfinance in Kenya, training church planters in Myanmar, or peacebuilding in Congo – that empowers transformative mission and development among the most vulnerable through the local church.

Our Priorities

All our work will promote spiritual, social, and environmental wellbeing among the most vulnerable.

Our Story

EFM founder Colby May visited the Democratic Republic of Congo in 2013. He experienced the devastation brought by years of civil war, but also witnessed the transformative, healing power of the local Congolese church.

With years of experience in the field of energy management, Colby and his wife Amanda felt God’s call to steward their expertise for the work of God’s kingdom around the world. They started EFM in 2017.

Our sister organization Energy for Purpose (EFP) uses 40% of its revenue to fund EFM’s projects.

Since our founding, we have worked with global partners to pioneer holistic mission and development projects in South Asia, the US, Congo, Myanmar, Kenya, Uganda, and Colombia.
