Inden is a municipality in the district of Düren in the state of North Rhine-Westphalia, Germany. It is located on the river Inde, approx. 10 km north-west of Düren. In the area around Inden lignite is extracted in open-pit mines. One mine is being rehabilitated with lake, park, solar power and energy storage.[3] Several hundreds of inhabitants have been resettled in the 1990s and 2000s because of these activities.[citation needed]
