This document discusses geothermal energy as a renewable energy source. It defines geothermal energy as heat from the Earth and notes that it provides clean energy around the world. It then explains that fossil fuels currently account for 70% of global energy use and prices have risen significantly in recent years. As such, geothermal energy is presented as one of the best solutions due to its efficiency - requiring up to 75% less energy than fossil fuel systems for heating and cooling through utilizing the stable temperatures below the Earth's surface.

2. What it is? The Definition
• Geothermal energy is defined as heat from
the Earth. It is a clean, renewable resource
that provides energy around the world in a
variety of applications and resources. thermal
energy generated and stored in the Earth.

3. What it is? The Definition (Cont.)

4. Why to use?
• Now days we are living in an energy crisis
period where the energy prices are getting
higher each day.
• Fossil fuels account for 70% of all energy use
globally.
• the prices of the fuel had been risen for more
than 300% among the lost 3 years in Jordan.

5. Why to use (Cont.)
The common heating system in Jordan
• the central heating system is the most
popular, which include a boiler, pumps, pipes
and radiators.
• The water temperature reaches an average of
50 ⁰C.
• The system efficiency does not exceed more
than 25% (why)?

6. Why to use (Cont.)
the common cooler systems in Jordan
• Split units are the most common
• Efficiency of these units does not exceed 40%

7. Why to use (Cont.)
• Because of that; the geothermal energy is one
of the best solutions.

8. Why to use (Cont.)

9. Why to use (Cont.)
• Geothermal heating and cooling system are at
least 3 times more efficient than fossil fuel
systems in energy consumption.
• 75% less energy than oil.
• 48% less energy than natural gas.
• 33% less energy than air source heat pumps
and central air conditioners.
• What required just a little amount of power to
run the distribution fan, compressor.

10. Implementation
• Small amount of equipments required (Pipes,
heat exchanger, pump, and fan).

11. How its work

12. How its work

13. Safe and Clean
• No Flame
• No Flue
• No Odors
• No danger of fire of fumes.
• You can benefit from less dust and better
indoor air quality
