Break up with your electricity retailer and join a renewable energy community that offers a free exchange of renewable energy for one low monthly fee. Each month you receive a guaranteed amount of energy for a low monthly fee and in return, some of the energy stored in your sonnenBatterie will be used to assist in the stabilisation of your peer to peer electricity grid.
