The idea to conserve resources came from their children: Kattrin Sippel and her husband Thoralf Räsch first bought a hybrid car a year ago, followed by 22 solar modules on the roof and a charging box for the car in the garage. The trip to the gas station has thus become superfluous. The sustainable family home was funded with money from the green electricity certification of the "MANN Cent" tariff. This green electricity product from MANN Naturenergie GmbH bears the Green Electricity label.
The Grüner Strom-Label supports the nature-friendly expansion of renewable energies by obliging suppliers of certified green electricity products to invest a fixed amount per kilowatt hour consumed in energy transition projects. In total, more than 1,300 energy transition projects have already been realized and co-financed. These can include wind farms, tenant electricity projects, and electromobility concepts. But they also include programs for private customers to promote an ecological energy supply in their own homes, as in the case of the Sippel family, who as a customer of "MANN Cent" now benefit from the green electricity subsidy themselves.
The photovoltaic system on the roof of Kattrin Sippel and Thoralf Räsch was subsidized with 2,000 euros. Since the 22 solar modules send energy to the storage tank, the household's electricity costs have been drastically reduced. On an annual average, the savings amount to 60 to 70 euros per month. "So our electricity costs have pretty much been cut in half," the couple is pleased to note.
After the photovoltaic system on the roof of their semi-detached house, a charging box was created in the garage to supply their cars with electricity. The heart of this overall package is an electricity storage unit in the garage of the family of four. This also serves as an energy control center. In real time, it can be checked how much electricity is generated by the solar cells on the roof or how much of it flows into the e-cars.
