What Are Some Examples of Geothermal Energy Use in Ancient Times?

Geothermal energy is a type of renewable energy that is generated and stored in the Earth’s crust. It has been used by humans for thousands of years, with evidence of its use dating back to ancient times. In this article, we will explore some examples of geothermal energy use in ancient times.

The Ancient Romans

The ancient Romans were pioneers in the use of geothermal energy. They built bathhouses and heated them using hot water from natural hot springs.

These bathhouses were not only a place for people to bathe but also served as social gathering places. The most famous example of Roman bathhouses is the Baths of Caracalla, which was built in Rome in 212 AD.

The Ancient Greeks

The ancient Greeks also used geothermal energy for heating purposes. The city of Athens had a system of underground pipes that carried hot water from natural hot springs to public baths and private homes. The Greeks believed that bathing in hot water had medicinal properties and could cure various illnesses.

The Maori People

The Maori people, who are indigenous to New Zealand, have been using geothermal energy for cooking and bathing for centuries. They use natural hot springs to cook their food by placing it in baskets that are then submerged in the hot water. They also use these hot springs for bathing and believe that the minerals in the water have healing properties.


In conclusion, geothermal energy has been used by humans for thousands of years, with evidence dating back to ancient times. The ancient Romans, Greeks, and Maori people are just a few examples of civilizations that utilized this form of renewable energy. As we continue to search for sustainable sources of energy, it’s important to look back at history and learn from those who came before us.
