PRESENTED BY GROUP 2

2. What is Geothermal Energy?

3. DEFINITION/DESCRIP
TION
•Refers to the heat within
the Earth

4. ORIGIN/HISTORY
• Native people used
geothermal energy long long
time ago, for different uses.
• Evidence shows that native
American used geothermal
energy for industrial uses.

5. ORIGIN/HISTORY
• 1904 – first geothermal
power plant which took place
at Ladrello, Italy

6. ORIGIN/HISTORY
• July 1977 – first geothermal power
plant in the Philippines was made at
Leyte.

7. TYPES OF GEOTHERMAL
POWER PLANT

8. TYPES OF GEOTHERMAL
POWER PLANT
Dry Steam Power
Plant
- is the direct use
of steams from
geothermal source/
reservoir to spin the
turbines of the
generator.

9. TYPES OF GEOTHERMAL
POWER PLANT
Flash Steam Power
Plant
-is the taking of high-
pressure hot water
from the inside of the
earth and coverts it
into a steam to
generate the generator.

10. TYPES OF GEOTHERMAL
POWER PLANT
Binary Cycle Power
Plant
- transferring of heat
from one geothermal hot
water to another water
which produces steams to
drive a generator turbine

11. ENVIRONMENTAL CONCERNS/
ISSUES/ PROBLEMS AS A
RESULT OF ITS UTILIZATION

12. • Release of Greenhouse gases
• H2S, carbon monoxide, and
sulfur dioxide emission
• sulfur dioxide and silica emissions
• Release of toxic heavy metals
• May cause earthquake
• May cause burning upon contact

13. MANAGEMENT PLANT
Plan Do Check Possible Outcome
1. Converting Geothermal
Vents into electrical
powerplant/electricity
a. Model of the
powerplant
b. Reuse of any possible
gas emitted by the
vents
c. Water filtration
 Utilize the
geothermal
vents properly
 Search/find
blueprints
regarding to this
geothermal vents
 Iceland geothermal
power plants and
water filtrarion
management
process
 More reliable
sources of
electricity
 Less pollution
 Innovation of
different scientist
can be
used/utilized
 Less cost on
producing
electricity
 More production
of clean water
 Lessen the
hazardous effects
of geothermal
vents

14. MANAGEMENT PLANT
Plan Do Check Possible Outcome
2. Transporter battery
 To preserve
emergency
energy
 The outline of the
plan/project should
be passed in the
DENR and other
related
organizations
 Hire an
engineer/expert
regarding to the
production of
transporter battery
 Create more
transporter battery
 Geothermal energy
will create reserved
energy for the
transporter battery
for the emergency.
 To have an
electricity on a
community even if
it is black out
 To prevent short
circuits of the
function of
geothermal power
plants

15. CONCLUSION
Geothermal energy is a renewable energy in a form
of heat which generated from within the Earth. It
has been used by human since l o n g t i m e a g o .
