What is geothermal energy?
Geothermal energy covers all the applications that use the heat contained underground in the subsoil or in groundwater.
This resource is used to produce heat, cold and electricity, which is then distributed through the networks.
Geothermal energy is renewable, local, environmentally-friendly, energy-efficient and economical, but its use still remains limited in comparison with its huge potential.
Today, 90 countries use geothermal energy.
In some countries, geothermal energy represents 22% of domestic output.
