Geothermal energy is a very simple idea. Deep below the crust and upper mantle of the Earth temperatures are incredibly high. Thermal mapping can show where to find accessible hot spots below the surface. These hot spots can be utilized to provide energy in the form of heat transference.

One way to envision this concept is by thinking of a volcano or a geyser. The heat produced above the Earths surface by the energy of a volcano or geyser is intense. This energy source is easily seen. By placing piping near these sources water or steam can be captured.Never heard of this before? Get up to speed here. The water or steam can than be used as heat or turned into electricity. Imagine the possible energy available through this process if energy stored below the surface can be captured and brought up.

Several countries have begun using Geothermal Energy. Italy began its program in 1904 with enough energy to light 5 lamps. Many environmental agencies recommend utilizing this type of power. Programs and incentives help defer the initial costs allowing countries such as the United States to increase its use of Geothermal energy sources. According to the Earthy Policy Institute the United States has more than 120 new projects underway.
