Geothermal Power

Geothermal energy production is a renewable energy source that extracts the heat from the earth's interior. The cost of geothermal energy production is greatly dependent upon how close to the earth's surface are located geothermal vents. In locations such as Iceland and Hawaii where there exists active volcanic activity, geothermal energy is an attractive source of renewable energy.
