Table description


This table shows the withdrawal of heat and cold. Heat is a form of energy. The use of shallow geothermal cold avoids the consumption of electricity for cooling. Figures have been broken down into deep geothermal heat and geothermal energy with or without heat pumps.

Geothermal energy is a form of renewable energy.

With deep geothermal heat, the pumped up water is sufficiently warm (approximately between 60 and 90 degrees Celsius) for direct consumption via a heat exchanger. The main application is the heating of greenhouses.

With shallow geothermal energy, the pumped water is usually not warm enough (about 10 degrees Celsius) for direct consumption. This is why heat pumps are often used to bring the temperature to a sufficiently high level.

Geothermal energy can be used both for heating and cooling. The main use of geothermal energy is the heating and cooling of office buildings.

Data available from:
1990

Status of the figures:
The figures in this table are definite up to and including 2019. Figures of 2020 are provisional.

Changes as of June 7th 2021:
Provisional figures of 2020 have been added.

Changes as of March 2021:
The explanations of 'Total geothermal energy' and 'Total shallow geothermal energy' has been adjusted.

When will new figures be published?
Provisional figures of deep geothermal heat and shallow geothermal energy in the form of heat used through heat pumps for the previous year are published each year in June.
Definite figures of all variables for the previous year appear each year in December.

Description topics

Extraction of geothermal heat
Extraction of geothermal heat for useful use.

The amount of extracted heat is usually calculated by multiplying three numbers:
1. the temperature difference between the extracted and infiltrated water
2. the amount of pumped water
3. specific heat of water
Extraction of geothermal cold
Extraction of geothermal cold for useful use.

The amount of extracted cold is usually calculated by multiplying three numbers:
1. the temperature difference between the extracted and infiltrated water
2. the amount of pumped water
