What is it?

Geothermal Energy is a
healthy, cheap, and nonpollutant way to get energy.
It has been used for
thousands of years
worldwide. It is very good
for our environment and
growing in popularity. It is
not as expensive to use as
other power facilities, The
only big problem is that only
certain places in the world
hold immense Geothermal
Energy.
How does it work?

Geothermal energy when
creating electricity and energy is
made by, When humans drill
holes into the ground deep
enough to reach a hot spot etc.
of rocks heated up underneath
ground. The power station
above uses a well to pump
down cool water onto the hot
rocks, this creates steam that
goes up another well where it
reaches the surface and
purifies. The purified steam
goes through turbines which
drive electric generators that
produce electricity and energy.

created the first Geothermal
Power Plant.
 When?: In 1904.
 Where?: The first Geothermal
power plant was created in
Landrello, Italy.

Healthier, Easier and more nonpollutant way of creating power
and energy.

There are only certain places where you can build Geothermal
Power stations, not every place has rocks hot enough to
produce steam. You will however find Hot-Spots when you
have:
The earths large oceanic crust plates collide and slide beneath
each other.
Spreading centers where plates begin to slide apart.
Hot-spots, which are fixed points in the mantle that produce a
constant flow of magma that rises to the earths surface. This is
also one of the reasons how volcanoes are formed.
Some places that have Geothermal Power stations are: United
States, Italy, New Zealand, Iceland, Mexico, Philippines,
Indonesia, and Japan.
