During the 1990s the production and supply of electric power in Germany ceased to be a monopoly. Following deregulation and consumer activity, there are now many suppliers offering electric power at a little more competitive prices. Germany still has some of the highest energy prices in Europe and beyond.
In Germany, the cost of electricity is not normally included in the additional charges (Nebenkosten) when renting a house or flat, so a decision needs to be made concerning power supplies.
Stadtwerke Neuss is the local utilities company of choice. All their electricity stem one hundred percent from renewable sources and is generated CO2 neutral. Good for the environment.
