This report for the U.S. Department of Energy summarizes the lessons learned from 16 government, educational and nonprofit groups that received grants to advance the deployment of plug-in electric vehicles (PEVs). Participants in projects across 24 states and the District of Columbia assessed the barriers to and opportunities for PEV deployment in their regions and prepared and executed readiness plans. The report is designed to be an accessible primer to the key issues in PEV deployment and a roadmap to the detailed research, toolkits, and sample language for local policies contained in the readiness plans.
