Green good intentions cause chaos in two German towns
Residents of the small town of Kamen, near Dortmund, had a shock this week when ground around a construction site collapsed as a result of drilling for a geothermal heat pump. Many locals had to be evacuated amid fears that houses could collapse, and many nearby buildings now have long cracks in the walls.
For residents of the southern German village of Staufen, the news came as little surprise: their town began sinking - and then rising - as a result of geothermal drilling almost two years ago.
