For some, the thought of geothermal energy might bring up the nation of Iceland, which has successfully harnessed this form of energy for many years. The United States Department of Energy's Geothermal Technologies Program is interested in such technologies as well, and their splendid site will be of great use to scientists, policy types, and others. The first thing new visitors will want to do is click on the Flash-enabled "Enhanced Geothermal Systems" animation, which describes their use and potential. After that, visitors can move on to the "Selected Topics" area, which includes a bit of information about U.S. geothermal history, photos of geothermal energy technology, and information on geothermal power plants and their operation. Visitors will also want to take a look at a few of the "Features" here, which include a report on the future of geothermal energy from MIT.
