Geothermal energy is thermal energy generated and stored in the Earth. It originates from the Earth's core where temperatures reach over 9,000 degrees Fahrenheit. Heat conducts from the core to rock, sometimes melting it to form magma. Magma heats rock and water near the surface. Geothermal power plants use this heated water or steam to power turbines that generate electricity. There are three main types of geothermal power plants: dry steam, flash steam, and binary cycle. Geothermal energy has advantages of being renewable, reducing emissions and fossil fuel dependence, while disadvantages include limited viable locations and upfront costs.

Geothermal Energy Resources or Geothermal power plantTesfaye Birara
Energy conversion is the process of changing one form of energy into another, a fundamental capability that enables modern civilization to function. It can occur in various ways, from converting the kinetic energy of wind into mechanical power through windmills to transforming solar energy into electrical energy in solar panels. This transformation is essential not just for daily usage but also for harnessing and utilizing natural resources more efficiently. In the context of rural electrification, this process plays a critical role. By converting available local energy resources into electricity, rural communities can access a stable and reliable power supply. This not only improves the quality of life but also supports economic development by powering homes, schools, businesses, and healthcare facilities. Consequently, energy conversion facilitates the broader goal of rural electrification, demonstrating the interconnection between technological innovation and societal advancement.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

2. •The word geothermal originated from the
Greek roots geo means earth and thermos
means heat.
• In simple means, Geothermal
energy is thermal energy generated and stored
in the Earth.
Thermal energy is the energy that is related to
the temperature of matter.
WHAT IS GEOTHERMAL ENERGY???
5. WHERE DOES IT COME FROM???
Initially, the energy transformed starts from way
down the Earth’s core – 4,000 miles down. At
the core, temperatures may reach over 9,000
degrees Fahrenheit.
Heat conducts from the core to surrounding
rock. Extremely high temperature and pressure
cause some rock to melt, which is commonly
known as magma.
6. Magma come upward since it is lighter
than the solid rock. This magma then
heats rock and water in the crust,
sometimes up to 700 degrees Fahrenheit.
This magma near the Earth’s surface is
what is used and transformed in power-
plants.
7. Geothermal energy is produced through
reservoirs, power plants and systems.
Geothermal reservoirs are generally classified as
being either low temperature (<150°C) or high
temperature (>150°C).
Generally speaking, the high temperature
reservoirs are the ones suitable for, and sought
out for, commercial production of electricity.
Geothermal reservoirs are found in “geothermal
systems,” which are regionally localized geologic
settings where the earth’s naturally occurring
heat flow is near enough to the earth’s surface to
bring steam or hot water, to the surface.
8. WHAT DO POWER PLANTS USE IN PRODUCING
GEOTHERMAL ENERGY???
Dry Steam- Steam is produced directly from the
geothermal reservoir to run the turbines that power the
generator, and no separation is necessary because
wells only produce steam. The image below is a more
simplified version of the process.
Flash Steam- Geothermally heated water under pressure
is separated in a surface vessel (called a steam
separator) into steam and hot water (called “brine” in
the accompanying image). The steam is delivered to the
turbine, and the turbine powers a generator. The liquid
is injected back into the reservoir.
13. Binary Cycle-
Known as binary geothermal plants, the facilities that
make this possible reduce geothermal energy’s already
low emission rate to zero.
The geothermal water (called “geothermal fluid” in the
accompanying image) heats another liquid, such as
isobutene or other organic fluids such as
pentafluoropropane, which boils at a lower temperature
than water.
The two liquids are kept completely separate through
the use of a heat exchanger, which transfers the heat
energy from the geothermal water to the working fluid.
The secondary fluid expands into gaseous vapour.
The force of the expanding vapour, like steam, turns the
turbines that power the generators. All of the produced
geothermal water is injected back into the reservoir.
17. Flash/Binary Combined Cycle:
This type of plant, which uses a combination
of flash and binary technology, has been used
effectively to take advantage of the benefits of both
technologies.
In this type of plant, the portion of the geothermal
water which “flashes” to steam under reduced
pressure is first converted to electricity with a
backpressure steam turbine and the low-pressure
steam exiting the backpressure turbine is
condensed in a binary system.
18.
19. WHAT ARE THE ADVANTAGES OF GEOTHERMAL
ENERGY PRODUCTION AND USAGE?
Geothermal energy does not produce any pollution, and does not
contribute to the greenhouse effect.
The power stations do not take up much room, so there is not much
impact on the environment.
Geothermal energy generally involves low running costs since it
saves 80% costs over fossil fuels and no fuel is used to generate
the power.
Dependence on fossil fuels decreases with the increase in the use
of geothermal energy. With the sky-rocketing prices of oil, many
countries are pushing companies to adopt these clean sources of
energy.
Since ancient times, people having been using this source of
energy for taking bath, heating homes, preparing food and today
this is also used for direct heating of homes and offices.
Geothermal energy on the other hand has created many jobs for
the local people.
20. WHAT ARE ITS DISADVANTAGES???
The big problem is that there are not many places where you
can build a geothermal power station. You need hot rocks of
a suitable type, at a depth where we can drill down to
them. The type of rock above is also important, it must be of
a type that we can easily drill through.
Sometimes a geothermal site may "run out of steam",
perhaps for decades.
Hazardous gases and minerals may come up from
underground, and can be difficult to safely dispose of.
To get geothermal energy, requires installation of power
plants, to get steam from deep within the earth and this
require huge one time investment and require to hire a
certified installer and skilled staff needs to be recruited and
relocated to plant location. Moreover, electricity towers,
stations need to set up to move the power from geothermal
plant to consumer.
21. TRIVIA:
The Philippines, which generates 23% of its
electricity from geothermal energy, is the
world’s second biggest producer behind the
U.S.
The first geothermal power station was built at
Landrello, in Italy, and the second was at
Wairekei in New Zealand.
