The right connections
Many public utilities, such as TelDaFax Energy or the Cologne-based E Wie Einfach, now provide one-stop shopping for electricity and gas.
Depending on how much energy you use, the nationwide companies eprimo, FlexStrom and Yello Strom can also be inexpensive alternatives.
Other national providers appeal not to the thriftiness, but rather to the environmental awareness of consumers.
Customers can buy electricity totally from environmentally friendly sources from Greenpeace Energy and Düsseldorf-based Naturstrom.
