Renewable energy including solar and wind generation or an atomic opt out is highly complex in Germany. Following deregulation and consumer activity, many suppliers offer electricity but Düsseldorf continues to have some of the highest energy prices in Europe.

When expats rent a house or flat, the cost of electricity is not normally included in the additional charges, Nebenkosten, so self-sourcing is normally recommended. Originating from the late eighteen hundreds, Stadtwerke Düsseldorf is the local utilities company of choice in Düsseldorf. They generate some forty percent of their own electric power.
