2. What is
Geothermal Energy?
• Geothermal energy refers to
the energy that is generated
and stored in the earth.
• This energy is derived from
the heat that is obtained in
the earth's core.

3. • Geothermal energy is
renewable energy
source.
• Geothermal energy
belongs to energy
sources that can be
directly used.
• Geothermal power
plants have minimal
land and freshwater
requirements
• The biggest
disadvantage of
geothermal energy are
high upfront costs.
• Small number of
countries that currently
harness geothermal
energy.
• Enhanced geothermal
systems can trigger
earthquakes

4. Effects Of Geothermal Energy
POSITIVE EFFECTS
• Useful minerals, such as zinc and silica, can be
extracted from underground water.
• Geothermal energy is “homegrown.” This will
create jobs, a better global trading position and
less reliance on oil producing countries.
• In large plants the cost is 4-8 cents per kilowatt
hour. This cost is almost competitive with
conventional energy sources.
• Geothermal plants do not require a lot of land, 400m2
can produce a gigawatt of energy over 30 years.

5. NEGATIVE EFFECTS
• Extracting large amounts of water can cause
land subsidence, and this can lead to an
increase in seismic activity.
• Power plants that do not inject the cooled
water back into the ground can release H2S,
the “rotten eggs” gas.
• There is the fear of noise pollution during the
drilling of wells.
