Geothermal resource potential

Definition

Geothermal resource potential refers to the capacity of an area to generate geothermal energy based on its geological characteristics and the thermal activity present. This potential is determined by factors such as temperature gradients, subsurface geology, and hydrothermal systems, which play a crucial role in assessing the viability of geothermal projects. Understanding this potential is key for evaluating the economic feasibility and planning of geothermal energy systems.
