Case Studies of State Support for Renewable Energy

About the Case Study Series

A number of U.S. states have recently established clean energy funds to support renewable electricity. The 15 states that have established these funds to date are expected to collect $3.5 billion between 1998 and 2012 for renewable energy investments. This represents a new trend towards aggressive state support for renewable energy, but few efforts have been made to report and share the early experiences of these funds.

Berkeley Lab, in collaboration with the Clean Energy Group, has initiated a case study series that will report on the use of these clean energy funds. The primary purpose of this series is to briefly report on the innovative programs and administrative practices of state (and some international) clean energy funds, to highlight additional sources of information and to identify contacts. Our hope is that these case studies will be useful for administrators of clean energy funds and other stakeholders that are interested in learning about the pioneering renewable energy efforts of newly established clean energy funds. We expect to produce several new case studies each year.
