Netherlands: geothermal energy from a former coal mine .
happens in Heerlen, the Netherlands town, where an old abandoned coal mine now for over 30 years has been converted into a modern source of geothermal energy. This project Minewater, recently went into operation to provide heating or cooling buildings, including 350 homes and businesses of the old Dutch town. The system uses the branches of the underground quarry now completely flooded with water, which at that depth indicates a temperature of 32 ° C, and accessed through five wells dug later in different areas, each 700 feet deep. The wells in question pump water to the surface at a speed of 80 cubic meters per hour, bringing the mass at a temperature of 28 ° C. At this level, a system extracts the heat and be redirected to the hydraulic system of the radiators, while the water, now cooled, be sent back 450 meters underground. A new way to say "really" goodbye to fossil fuels.
