Geothermal: Environmental Reports and Case Studies

Environmental reports and case studies regarding tribal geothermal energy projects.

The following table provides access to environmental reports (e.g., environmental assessments, environmental impact statements, records of decision) and case studies for geothermal energy projects undertaken by tribes. You may search the entire repository of relevant reports and case studies by document type, energy resource, project location, and/or tribe using tools provided in the Document Library.

Other Resources

The following Web sites provide access to repositories of environmental reports and case studies for a wide variety of energy projects, including tribal and non-tribal projects and projects involving other types of energy resources.

Tribal Renewable Energy Case Studies

The U.S. Department of Energy (DOE) Tribal Energy Program maintains a Web site with information about tribal renewable energy case studies, including geothermal energy projects. The program's tribal Geothermal Energy Resources page provides maps showing geothermal resources in the vicinity of individual reservations, searchable by state.

Geothermal Direct Use Case Studies

The Oregon Institute of Technology GeoHeat Center published the Geothermal Direct Use Case Studies report in 2005 providing overviews of a number of geothermal direct use applications.

Energy Consumption and Renewable Energy Development Potential on Indian Lands

Energy Consumption and Renewable Energy Development Potential on Indian Lands is a report published in 2000 by the DOE's Energy Information Administration (EIA) that examines electricity use, prices, and renewable energy potential for both Federally Recognized Indian Reservations and Tribal Jurisdictional Statistical Areas in Oklahoma.

Environmental Studies Repositories

A number of organizations maintain repositories of environmental impact statements (EISs) and environmental assessments (EAs), some of which are specific to energy development on tribal lands.

The U.S. Environmental Protection Agency (EPA) Environmental Impact Statement Database provides a searchable listing of draft and final EISs that have been submitted to the EPA (searchable by keyword in title, publication date, agency, and state). The EPA does not provide a copy of the document itself, but information regarding summaries of EPA comments can be obtained at the Web site.

The DOE Office of the General Counsel provides lists and links to various DOE NEPA Documents (draft and final EISs, EAs, supporting documents, and supplemental analyses) prepared by the agency.

The Federal Energy Regulatory Commission eLibrary provides a search menu to find EAs, EISs, environmental studies, and a full range of supporting documentation prepared by the agency.
