State of the States 2008: Renewable Energy Development and the Role of Policy

Elizabeth Brown

Research output: NRELFact Sheet


This report provides insights into the status of renewable energy development at the state level. Renewable resources are increasing in development overall, but state development varies by resource and rates of change. The factors contributing to renewable energy development at the state level are identified and discussed, including the challenges of understanding the role of different factors indevelopment. The report also compiles and evaluates the status of 'best practice' state policy design and connects the existence of some policies with increased renewable energy development through correlation analysis. The report also proposes a strategy for better understanding the role of policy in renewable energy development, based on market-transformation principles. Correlation analysisillustrates the potential for further application of these principles to renewable energy. The final section provides resources for state policy makers for better understanding and developing renewable energy resources.
