Who We Are
And Why It Matters
Efficiency First California (EFCA) is a non-profit trade organization that represents and promotes clean energy contractors in California. For over 20 years, we have helped contractors like you succeed.
EFCA is directly involved in state policy discussions. One of our core responsibilities, as a trade organization, is to help contractors be aware and involved in state energy policy.

We partner with industry stakeholders who share our common goals. Working collaboratively, we have been able to influence policy on a large scale.
We want to help you grow your business. Our monthly blog and advocacy update help you make well-informed decisions about the future of your business.
