E) a dry heat

Geothermal energy provides a constant source of heat and is not dependent on weather conditions or variable factors like wind or solar power. This makes it a more dependable energy source than some other forms of alternative energy. Heat from the sun (A) and radiated heat (B) are not specific to geothermal energy, while heat from steam (C) is a result of geothermal processes but not a defining characteristic of geothermal energy. Dry heat (E) is also not specific to geothermal energy.
