o Geothermal energy- the energy produced
by heat within the Earth.
o Geothermal energy can be found in
volcanoes, hot springs, and geysers.
o Geothermal energy is a green house gas
and does not produce waste.
 Geothermal power plants are built in areas where
the Earth produces hot water or steam.
 Today, there are almost 150 geothermal power
plants that are found in Iceland, Italy, New Zealand,
and the United States.
 Geothermal energy can be
found in certain places
around the world so
therefore geothermal
power plants can only be
formed in certain places
around the world
 When heated water is taken
from the ground the rocks
become very dry.
 The rocks may shift or break
causing tiny earthquakes.
 Workers have to be extremely
careful where they place
geothermal power plants
 In deserts they produce very
little geothermal energy because
of the lack of ground water.
 In the Netherlands they have
good design and engineering of
geothermal wells.
People must drilling these
wells must have supervision on
behalf of the client.
The maintenance and repair of
geothermal wells and
installations take a lot of time
and money.
 One use is for heating homes and
other buildings.
 Also its used for generation
electricity.
 To get the energy we use
geothermal pumps.
 It’s a clean source of energy and
does not run on fossil fuels.
 Geothermal energy supplies less
than 10% of the world’s energy.

 In the United States, most
geothermal reservoirs are in Nevada
and California.
 Almost everywhere that has shallow
ground or upper 10 feet of the
Earth’s surface maintains a nearly
constant temperature.
 The temperatures are in between
50°F and 60°F (10°Cand 16°C)
 It can easily be found along the
“Ring of Fire”
 Boreholes: a heating system to get
geothermal energy.
 Ground source heating pump, for
heating
 BTES and heat pump for heating and
limited a cooling system
 Aquifer Thermal Energy Storage: a cooling/heating
system
 Cooling only not for heating
 Charges in cold or hot water
 Heat pump for heating in the summer
 Has a cooling and heating pump also used for
heating
 ATES stands for aquifer thermal energy storage
 High temperature ATES/BTES (the pilot stage)
 Is a direct heating system by storage of waste heat.
 Some foreign firms that are joining forces with the
US companies that specialize in geothermal energy
storage are discussing the ATES
 Geothermal energy is heat stored within the Earth.
 The center of the Earth is a core made of molten
metal.
 The temperature at the Earths core is at least as hot
as the surface of the sun.
 This is hot enough to melt the surrounding rock,
turning it into magma
 Then the magma rises to the surface and heats the
ground.
Disadvantages
 A disadvantage of geothermal energy is it is
expensive the price is $1, 500 to $3,000
Fun Facts
 Geothermal energy is gathered by a tube.
 To gather and store geothermal energy it
usually costs 1,150 -3,000.
 The amount of energy gathered is very little
compared to other energy sources.
 It is renewed by all of it resources.
 Why can you not have a geothermal power plant in
the desert?
 Because there is not a good supply of ground water.
 What is a borehole?
 A heating system to get geothermal energy.
