A geothermal reservoir is a powerfulsource of energy
Geothermal reservoirs can
reach temperatures of 370 C.
(more than 3 times boiling).

Dry Steam Power Plants
The steam goes directly to a
turbine, which drives a
generator that produces
electricity.
This is the oldest type of
geothermal power plant.
The steam eliminates the
need to burn fossil fuels to
run the turbine.

Today after 90 years, the Lardello field is still producing

Flash Steam Powerplants
It utilizes hydrothermalfluids above 400 degrees F
that can be used in flash
plants to make electricity.
Fluid is sprayed into a tank
held at a much lower
pressure than the fluid,
causing some of the fluid to
rapidly vaporize, or "flash,"
to steam.
The steam eliminates the
need to burn fossil fuels to
run the turbine.

Binary Cycle Power Plant
Hot geothermal fluid and asecondary fluid with a much
lower boiling point than
water pass through a heat
exchanger.
Heat from the geothermalfluid causes the secondary
fluid to flash to steam,
which then drives the
turbines.
Most geothermal power
plants in the future will be
binary-cycle plants.

Those white plumes you see at geothermalpower plants are steam (water vapor).Geothermal plants do not burn fuel orproduce smoke.

People who live in these areas are receivingelectricity from geothermal power plants.There are around 24 countries using geothermal energy to
produce electricity. Prominent names are USA, Philippines,Mexico, Indonesia, Italy, Japan, New Zealand, Iceland, Costa
Rica, Kenya, EI Salvador, Nicaragua, Guatemala, Turkey and
France. Among them USA has the highest production of 17917
GWh/year. Countries like Philippines with 18.8%, Iceland 17.5%and EI Salvador 22% having the most prominent percentage of
geothermal power in their total energy production.
There are EGS systems currently being developed and tested
in France, Australia, Japan, Germany, USA and Switzerland.There are several EGS projects that are already or will soon
produce power.

Costs

The significant costs associated with an EGS project are:
Drilling cost.
Reservoir stimulation.
Power plant.
Transmission and other regulatory costs.
Wells in the depth ranges from 1,500 m to 10,000 m were
modeled in three categories: shallow wells (1,500-3,000 m),
midrange wells (4,000-5,000 m), and deep wells (6,000-10,000
m). Well costs were estimated for depths from 1,500 m to
10,000 m.

EGS is receiving attention in the world stage because of its
lower operation and maintenance cost, environmental
cleanliness and relatively lower cost of the energy produced.

Geothermal Heat Pumps(GeoExchange systems)

Geothermal heat pumps can be used almost everywhere in
the world, without a geothermal reservoir. The insulating
properties of the earth, just below our feet, can keep us warm
or cool.
In a poll, over 95% of people who had installed a geothermalheat pump said they would recommend it and would do it
again.
