CEE is a nonprofit consortium of efficiency program administrators, primarily large investor-owned utilities from across the United States and Canada, that work together on common approaches to advancing efficiency. Energy efficiency is consistently regarded as the most cost-effective means of securing additional energy resources. It also directly offsets the need to generate additional energy and is one of the most direct means of greenhouse gas mitigation available. By working together at CEE, program administrators leverage the effect of their funding dollars and exchange information on effective practices to achieve greater energy efficiency for the public good.
