Workbooks:

Geothermal Small Business Workbook - For entrepreneneurs, small business, and developers, this workbook provides the information and tools for understanding geothermal applications-both direct use and small-scale power generation and how to write a business plan. This workbook, released in May 2003 is on PDF and can be downloaded.

Reports:

Assessing the Potential for Renewable Energy on Public Lands - A report released in February 2003 by the Department of the Interior and the Department of Energy, which identifies and evaluates renewable energy resources on public lands.

CDEAC Geothermal Task Force Report - In January 2006, The Western Governors’ Association’s (WGA) Clean and Diversified Energy Advisory Committee (CDEAC) released its report on the potential of geothermal energy to power states throughout the country, including Alaska, Arizona, California, Colorado, Hawaii, Idaho, Nevada, New Mexico, Oregon, Utah, and Washington. The report was created as part of WGA's Clean and Diversified Energy Iniative for the West Policy Resolution, which seeks to "achieve a goal to develop 30,000 MW of clean energy in the West by 2015 from resources such as energy efficiency, solar, wind, geothermal, biomass, clean coal technologies, and advanced natural gas technologies.”

NREL Geothermal Potential Report - On May 16, 2006, the National Renewable Energy Laboratory (NREL) in Golden, Colorado hosted a geothermal resources workshop with experts from the geothermal community. The purpose of the workshop was to re-examine domestic geothermal resource estimates. The participating experts were organized into five working groups based on their primary area of expertise in the following types of geothermal resource or application: (1) Hydrothermal, (2) Deep Geothermal Systems, (3) Direct Use, (4) Geothermal Heat Pumps (GHPs), and (5) Co-Produced and Geopressured.

MIT Report - The Future of Geothermal Energy: The Impact of Enhanced Geothermal Systems (EGS) on the United States in the 21st Century - This comprehensive MIT-led study of the potential for geothermal energy within the United States was released January 24, 2007. It found that mining the large quantities of heat that reside as stored thermal energy in the Earth's hard rock crust could supply a substantial portion of the electricity the United States will need in the future, probably at competitive prices and with minimal environmental impact. Specifically, the panel found that 100,000 MW of EGS could be developed by 2050.

An Evaluation of Enhanced Geothermal Systems Technology - This report examines the conclusions of the MIT study, The Future of Geothermal Energy, and determines whether those conclusions are well-founded. The report presents the results of an eight-month study by the Department of Energy (DOE) concerning the technological requirements to commercialize a new geothermal technology, Enhanced Geothermal Systems (EGS). The report also evaluates the state of technology available in today’s commercial geothermal industry and other EGS-related industries.

Geothermal Risk Mitigation Strategies Report - The Department of Energy released this report on February 15, 2008. It provides an overview of general financial issues for renewable energy investments; geothermal energy investment barriers and risks; and recommendations for several incentives and government instruments that should be considered to stimulate increased investment in geothermal energy development.
