The American Reinvestment and Recovery Act (ARRA) provided billions of federal dollars to support investments in energy efficiency at the state and local level. How state energy offices chose to allocate those funds and how those programs interacted with existing utility customer-funded programs is the subject of this report from Lawrence Berkeley National Laboratory. The study examines these choices and interactions for insights into an emerging and increasingly complex world of multiple program administrators and funding sources. The paper suggests the Recovery Act experience has clear implications for the future of U.S. energy efficiency.
