Geothermal Energy
Definition:
* Geothermal energy is thermal energy generated and stored in the Earth. * Thermal energy is the energy that determines the temperature of matter. * The Geothermal energy of the Earth's crust originates from the original formation of the planet (20%) and from radioactive decay of minerals (80%). * The geothermal gradient, which is the difference in temperature between the core of the planet and its surface, drives a continuous conduction of thermal energy in the form of heat from the core to the surface. * The adjective geothermal originates from the Greek roots γη (ge), meaning earth, and θερμος (thermos), meaning hot. http://en.wikipedia.org/wiki/Geothermal_energy

Advantages:
* Almost entirely emission free.
* No carbon.
* The process can scrub out sulfur that might have otherwise been released. * No fuel required (no mining or transportation).
* Not subject to the same fluctuations as solar or wind.
* Smallest land footprint.
* Virtually limitless supply.
* Inherently simple and reliable.
* Can provide base load or peak power.
* Already cost competitive in some areas.
* Could be built underground.
* Some level of geothermal energy available most places.
* New technologies show promise to utilize lower temperatures. Disadvantages:
* Prime sites are very location-specific.
* Prime sites are often far from population centers.
* Losses due to long distance transmission of electricity. * Water usage.
* Sulfur dioxide and silica emissions....
