State Support for Clean Energy Deployment: Lessons Learned for Potential Future Policy

April 30, 2011

The National Renewable Energy Laboratory recently published, State Support for Clean Energy Deployment: Lessons Learned for Potential Future Policy (PDF 1.0 MB). Proposed federal clean energy initiatives and climate legislation have suggested significant increases to federal funding for clean energy deployment and investment. Many states and utilities have more than a decade of experience and spend billions of dollars every year to support energy efficiency/renewable energy (EE/RE) deployment through programs that reduce the cost of technologies, provide financing for EE/RE projects, offer technical assistance, and educate market participants. Meanwhile, constraints on public expenditures at all levels of government continue to call upon such programs to demonstrate their value. This report reviews the results of specific incentives and financing tools used to encourage clean energy investment. Lessons from such programs could be used to inform the future application of EE/RE incentives and financing tools.
