geothermal energy

What is geothermal energy?

• Derived from the center of the earth

• captured and harnessed to generate electrical energy

What is conventional geothermal energy?

• To drive electric turbines, geysers, or high-pressure depths are dug to harness steam which will be converted into electricity

What is supercritical water?

• Produced when molten rock and water interacts

• It is believed that supercritical water has greater energy than steam

How do geothermal power plants work?

1. Steam from the supercritical water goes to the turbine

2. The used supercritical water and steam are cooled down in the cooling tower

3. The turbine, connected to the generator, spins and generates electricity

4. Supercritical water is collected from the volcano

5. After cooling down, the water and steam are sent back to the ground
