What is geothermal energy?


It gets heaten up by the core of the earth
It is used for home heating, opening a
potential for widespread exploitation
It costs between 2 and 10 US cents per
kWh
Geothermal energy in Europe:
Where is geothermal
energy in Germany?
How do we win
geothermal energy?
Our earth has a lot of energy
stored that can be extracted.
This geothermal energy has
been there since the
beginning of the formation of
our planet.
It has been used for spacial
heating and bathing since
ancient Roman times.
The earth's crust
The Earth's crust is like the skin of
an apple.
It is very thin in comparison to the
other three layers. The crust is
only about 3-5 miles (8
kilometres) long and about 25
miles (32 kilometres) thick.
The temperatures of the crust vary
from air temperature on top to
about 1600 degrees (870
degrees Celsius).
A geothermal energy plant:

The advantages of
geothermal energy
- The energy is renewable
- The cleanest energy
- High heat source
- No chemistry needed
- Good for the climate
The disadvantages of
geothermal energy
- Not widespread source of energy
- High installation costs
- Can run out of steam
- May release harmfully gases
- Difficult to transport
Costs of geothermal energy
The costs of Geothermal energy are
low depending on how you approach the use of energy.
Geothermal energy is heat contained within the
earth. This heat energy can be found almost anywhere. As
far away as remote deep wells in Indonesia and as close as
the dirt in our backyards.
What is geothermal energy used for ?
Geothermal energy can be used as a heat source in small end-use
applications, but the consumers have to be located close to the
source of heat.
Heat from the earth can be used in many ways, from large and
complex power stations to small and relatively simple pumping
systems.
