Geothermal electricity-generating systems do not produce harmful emissions like greenhouse gases, making them environmentally friendly. Additionally, the systems have a small footprint and can operate 24/7, providing reliable and sustainable energy. The heat source for geothermal energy is renewable and will not deplete over time.
Geothermal systems and reservoirs are classified on the basis of different aspects, such as reservoir temperature or enthalpy, physical state, their nature and geological setting. LOW-TEMPERATURE GEOTHERMAL FIELDS HIGH-TEMPERATURE GEOTHERMAL FIELDS HOT DRY ROCK GEOTHERMAL RESOURCE
Geothermal hot fractured rock, also known as Enhanced Geothermal Systems (EGS), involve injecting water into hot impermeable rocks to create fractures that allow enhanced heat extraction. This process increases the potential for geothermal energy production in areas previously considered unsuitable for traditional geothermal systems.
Geothermal technicians work outside to install, maintain, and repair geothermal heating and cooling systems. This includes tasks such as excavating to lay underground piping, connecting piping to indoor systems, and troubleshooting any issues that may arise. They also perform routine inspections to ensure systems are operating efficiently.

A geothermal design engineer is a professional who specializes in designing systems that utilize geothermal energy for heating, cooling, and power generation. They are responsible for creating plans and specifications for geothermal projects, ensuring that they are efficient, cost-effective, and environmentally sustainable. These engineers work closely with other professionals, such as geologists and project managers, to develop and implement geothermal systems.
The start-up time for geothermal energy systems varies depending on the specific type of system being used. Typically, geothermal power plants can be started up quickly, in a matter of hours. Direct-use geothermal systems that provide heating or cooling to buildings can be started up almost instantaneously.
The common types include forced air systems, radiant heating systems, steam heating systems, and geothermal heating systems.
Drills, to drill several thousand metres into hot rock.Pumps, to pump hot water and steam.Electricity turbines, to generate electricity.Cables, to connect to electricity grid.
Geothermal heating systems can increase indoor humidity levels if not properly controlled or balanced. The heat exchange process in geothermal systems may extract moisture from the ground, which can be released into the air inside the building. However, with proper system design and ventilation, excessive humidity can be mitigated.
