2   The most abundant place to find geothermal energy is Iceland.  Geothermal energy is found in the the form of volcanoes, hot springs, and geysers  It can also come from miles under ground in the core of the earth. It heats underground water until it turns into steam. The steam bursts through a crack or hole in the Earth’s crust as a geyser or hot spring. http://www.engineering.com/Videos/VideoPlayer/tabid/4627/videoId/649/geothermal-energy-process.a spx Where does it come from?

3   Geothermal energy is heat stored within the earth.  Geothermal energy is clean, reliable, and cost effective.  It’s availability is limited to areas near tectonic plates such as California and Nevada. What is Geothermal Energy?

4   Geothermal energy is used in many ways such as; heating hot water and to generate electricity to power homes and industries.  People also use geothermal energy when they bathe in hot springs.  Some people believe that bathing in the warm water and breathing the vapors from the hot spring can cure some diseases.  Using the Energy

5   The energy is made deep beneath the earth’s crust.  The earth has many layers, one being the iron core, which is the center of the earth.  Geothermal energy is not “made”, It is harvested from geothermal heat vents, which are mostly found in California, Nevada, and Oregon.  If the harvesters or the people collecting the energy find a very hot rock, they can pour water to create the steam they need to create the electricity. How it is made?

6   It is a sufficient and cost efficient form of energy.  There are lots of geothermal heat vents in hot places, though this also may be a con because they can still get solar energy from the sun in these hot places.  Another advantage of geothermal energy is the environment friendliness.  A very important pro is the reliability of this form of energy Pros

7  Some of the environmental dangers of geothermal energy are:  Land subsidence  Production of waste water with high mineral content  Disposal of hot water in the conversion process  Then there is the release of toxic gases such as: Hydrogen sulfide, ammonia, and Boron. Cons

8   At The Geysers, power is sold at $0.03 to $0.035 per kWh. A power plant built today would probably require about $0.05 per kWh. Some geothermal energy plants can charge more. The cost of geothermal energy

9  Ways it can be distributed Vertical Loop Horizontal loop Pond loop Open loop

10   Geothermal heat pumps are environmental. They generate no on site emissions and have the lowest emission among all heating and cooling technologies.  Geothermal heat pump systems, also known as "geothermal," are the most energy-efficient, environmentally clean, and cost-effective space conditioning systems available, according to the Environmental Protection Agency. The way it is distributed.

11   Geothermal energy supplies less than 10% of the world's energy.  Geothermal energy is sustainable because hot water can be re-injected into the ground.  Geothermal energy can be found in the form of volcanoes, hot springs and geysers.  Geothermal energy is used since ancient times in form of hot water.  Geothermal energy could produce 10 percent of US electricity by the year 2050. Fun Facts

12   Geothermal energy can be easily found and exploited along the "Ring of Fire" region.  Geothermal energy is extremely efficient (almost 100%) energy source where the only real sources of losing energy is from turbine friction.  Geothermal energy has only one real problem and that is the lack of easily accessible sites.  Geothermal energy's advantage is also the fact that geothermal power plants run continuously day and night with an uptime typically exceeding 95%.
