Technical companies think that in ten years, houses and companies in Enschede can be heated with a geothermal energy of 5 kilometers deep. The temperature of the earth in a depth of a few kilometers is high enough to make heat water.
After wind, sun and biomass energy sources, Enschede municipality has encountered geothermal activity. By that time it would work like this: in a suitable location, two holes are drilled to pump water around. Cold water goes in and hot water gets pumped out……. Of course, research has to be done like a test drill with soil samples.
Of course, research has to be still done such as a test-drill with soil samples and political negotiation has to be implemented about this technic.
