NREL geothermal regulatory and permitting toolkit for the U.S.
In a great website, the NREL RAPID toolkit provides fantastic geothermal regulations and permitting information for the United States.
In 2014, the National Renewable Energy Laboratory (NREL) began developing the Regulatory and Permitting Information Desktop (RAPID) Toolkit to act as a hub location from which users can easily and quickly access links to permit documents, processes, best practices, manuals and related information.
The RAPID Toolkit currently hosts information about bulk electricity transmission, geothermal, and solar technologies and is being expanded to include information about developing and permitting hydropower projects.
The Geothermal Regulations and Permitting information hosted on RAPID is quite extensive and very interesting.
