State of the States — The Role of Policy in Clean Energy Development

NREL's State of the States analysis looks at the growth of clean energy development that coincides with the implementation of specific state policies. Even though the analysis is carried out from the point of view of policymakers and researchers, the results also apply to companies with a stake in clean energy market growth and the public.
