How is geothermal energy harnessed?

How is geothermal energy harnessed?

Geothermal energy is harnessed by tapping into the Earth's internal heat. This can be done through various methods, such as using geothermal power plants or ground-source heat pumps.

What are the main methods used to harness it?

The main methods include dry steam plants, flash steam plants, and binary cycle power plants. Each method utilizes different techniques to convert geothermal heat into electricity.

Are there any environmental impacts?

Yes, while geothermal energy is generally considered clean, it can lead to land subsidence, water usage issues, and the release of greenhouse gases if not managed properly.

How efficient is geothermal energy compared to other renewable sources?

Geothermal energy is highly efficient, often providing a capacity factor of 90% or more, which is higher than many other renewable sources like wind or solar.

Can geothermal energy be used for heating as well?

Absolutely! Geothermal energy is commonly used for heating buildings through ground-source heat pumps, which transfer heat from the ground into homes.
