This presentation covers geothermal energy, a renewable energy source derived from the Earth's internal heat. It explains how geothermal systems work, types of geothermal power plants, global usage, environmental impact, and the future of geothermal technology.

1. Geothermal Energy: Power from
the Earth
• An Introduction to Geothermal Energy
• Presented by: [Your Name]
• Date: [Insert Date]

2. What is Geothermal Energy?
• - Heat energy stored beneath the Earth's
surface.
• - Originates from the Earth's core and residual
heat from formation.
• - Tapped for electricity and direct heating
purposes.

3. How Geothermal Energy Works
• - Wells drilled into geothermal reservoirs.
• - Hot water or steam is brought to the surface.
• - Drives turbines to generate electricity or
used directly for heating.

4. Types of Geothermal Power Plants
• - Dry Steam Plants: Use steam directly.
• - Flash Steam Plants: Use high-pressure hot
water.
• - Binary Cycle Plants: Use heat to vaporize a
secondary fluid.

5. Geothermal Energy Uses
• - Electricity generation.
• - Direct heating (buildings, greenhouses,
aquaculture).
• - Geothermal heat pumps for residential
heating/cooling.

6. Advantages of Geothermal Energy
• - Renewable and sustainable.
• - Low greenhouse gas emissions.
• - Reliable and available 24/7.
• - Small land footprint.

7. Limitations of Geothermal Energy
• - High upfront costs for drilling.
• - Limited to regions with geothermal activity.
• - Potential for surface instability or induced
seismicity.

8. Global Geothermal Usage
• - Major producers: USA, Philippines,
Indonesia, New Zealand, Iceland.
• - Used both for electricity and direct
applications.

9. Environmental Impact
• - Minimal air pollution.
• - Requires careful water and land
management.
• - Proper site selection reduces risks.

10. The Future of Geothermal Energy
• - Enhanced Geothermal Systems (EGS) for
wider adoption.
• - Integration with hybrid renewable systems.
• - Technological advancements lowering costs.
• - Growing role in clean energy transitions.
