California Contractor Advocacy
Building a clean energy future for all
Efficiency First California is actively engaged in California policy. We monitor communications from the California Energy Commission and the California Public Utilities Commission. When needed, we provide feedback to ensure regulations and policies consider the contractor’s role and the implications proposed regulations may have on contractors.
Your feedback as a contractor is critical for our efforts. We encourage your participation in policy discussions. We feel it is our role to represent your perspectives.
