Thanks to The Tim Traveller who brings us the largest open cut brown coal mine in the world. The coal is of poor quality with litlle calorific value and definitely carbon unfriendly. The mine is located in Hambach in Germany, and although it is recognised that this mine environmentally unsustainable, the government uses the coal to replace nuclear power stations shut down by environmentalists. I guess the greenies can’t have it both ways! The mine is 5km accross at its widest point!
