Geothermal energy is sustainable heat from the subsurface with which you can heat houses, buildings and greenhouses. Deep in the subsoil there is warm water in (porous) sand and rock layers. Geothermal, or geothermal heat, is extracted from hot water in these layers. In the Netherlands, geothermal energy is usually extracted at a depth of between 2 and 3 km, where the water has a temperature of 70 – 90 ℃.
Renewable heat source
Geothermal energy provides sustainable, renewable heat. Geothermal energy is a renewable source of heat because the heat is naturally replenished underground. In addition, it is a heat source that releases hardly any CO2, which is why geothermal / geothermal heat contributes to making the Dutch energy system more sustainable. It is a sustainable local and reliable alternative to natural gas.
