Tapping Earth's Internal Heat

Geothermal energy utilizes the heat originating from the Earth's core. This heat is continuous and available 24/7.

How it's Used:

• Electricity Generation: In areas with high heat flow near the surface (volcanic regions), steam or hot water is used to drive turbines connected to generators.
• Direct Use / Heating: Hot water from geothermal sources can be used directly for heating buildings (district heating), greenhouses, spas, and industrial processes.
• Geothermal Heat Pumps: Use the stable temperature of the ground or groundwater (even in non-volcanic areas) to provide highly efficient heating and cooling for buildings by transferring heat rather than generating it.

Advantages:

• Renewable and sustainable.
• Low greenhouse gas emissions.
• Reliable baseload power (unlike solar/wind).
• Heat pumps are highly energy-efficient.

Limitations:

• Large-scale electricity generation is geographically limited.
• High initial drilling costs.
• Potential release of some trapped gases (like hydrogen sulfide).
