The report examines the biggest U.S. geothermal markets and determines the capital costs needed to exploit those markets.

The biggest potential for geothermal energy applications in electricity production is in the western states, primarily in California, Nevada, Idaho, Oregon and Hawaii. In California, geothermal could provide about 20 percent of today’s electricity needs. In Nevada, 60 percent of the state's electricity could come from geothermal. And in Hawaii, geothermal could provide around 30% of the islands’ electricity needs. Most of the current development is taking place in Nevada and California.

Some of the key findings of the report are:

    • Glitnir estimates the investment requirement to service current projects to be some $9.5 billion. A total investment of $16.9 billion will be required to develop available resources over the next 8 years with a further $22.5 billion during the following 10 years.

    • Sales of geothermal powered electricity could increase from currently $1.8 billion to $11 billion, without taking into consideration the vast opportunities for the development of geothermal direct use applications, such as geothermal heat pumps.

    • The geothermal industry in the U.S. is still very fragmented, consisting of relatively few big companies and many small ones. Some of the smaller companies lack the financial strength to fully develop projects that in many cases could be profitable. Glitnir predicts there will be considerable consolidation in the industry in the next few years.

    • For successful development of the geothermal industry it will be necessary to increase the capacity of drilling equipment and related human resources. As the industry is recovering from a decline that took place in the late 1980s and is to some degree competing with the oil industry for human resources, it is crucial to train and educate people to work within the sector.
