Response #8 to "Geothermal Energy: Intelligent Use Of The Earth’s Heat"

Geothermal energy is a renewable source of energy in which the heat from the Earth's mantle is used to evaporate and heat water, and it can be used to heat homes and produce electricity. This is significant because no outside power is needed to be used, and the only byproducts of this process consist of steam (which will just fall as rain again) and the initial cost of setting up the process. You can't just drill a hole anywhere and expect to get geothermal heat from it. It varies as to how much there is, and the Western US is very fortunate in that it has a lot of potential spots. I-GET, which is a conference being held in Europe, is being held in part to address the limitations of the current technology and to develop more efficient ways of finding spots that contain geothermal heat, and then drilling down to it. Iceland, which is the world's most prominent user of geothermal heat, has doubled its supply of electricity. That shows how much potential geothermal energy has in the world.
