Geothermal Potential
The adjoining diagram reproduces the geothermal heat flux density in Europe. It was taken from the “Atlas of Geothermal Resources in Europe” (European Communities, 2002) and a sectional drawing of the earth was superposed.
The heat flux density is a physical dimension to quantitatively describe heat transferring processes. It is defined as the amount of heat flow that is exchanged across a unit area of a system, e.g. the amount of geothermal heat conducting to the earth’s surface. It can also be described as heat flow per area A.
The colours of the diagram indicate different geothermal potentials:
red = excellent potential
orange = very high potential
yellow = medium to high potential
green = moderate potential
blue = low potential
