Since September 2018, balcony PV modules may generally be connected in every apartment. Berlin has now greatly simplified the registration process. Berliners can thus become their own energy supplier with little effort and save cash.
Stromnetz Berlin GmbH has now greatly simplified the registration process. It now only requires an A4 sheet, which can be downloaded from the company's website. Various stakeholders from the ranks of Berlin's solar associations and companies collaborated on this simplification.
Balcony modules are already available for less than 300 euros and can recoup their initial costs through saved electricity costs after about four to six years. Due to manufacturer guarantees of up to 25 years for many of the devices, returns of up to 15 percent per year are possible. Before buying, it is essential to compare offers and prices.

The state of Rhineland-Palatinate is providing funding of 150,000 euros for a local heating network in Gimbweiler, which is to be supplied in future by means of a solar thermal open-space system and a woodchip system.
"The planned local heating network will supply a total of more than 80 buildings in the village with renewable energy," says Thomas Griese, State Secretary at the Rhineland-Palatinate Ministry for the Environment, Energy, Food and Forestry (MUEEF): "This includes a sports hall and a multi-generation house. I am excited about this project, because we need the commitment of the municipalities for a successful heat and energy turnaround!"
Griese handed over the funding notification to Mayor Martin Samson for a sub-project of the local heating network: the connection lines and the house transfer stations. In addition, the Gimbweiler receives funds from the federal government from the national climate protection initiative.
In the "Nahwärmeverbund Gimbweiler", the regenerative heat is generated by two woodchip boilers and a solar thermal open-space system. The solar thermal supported heat generation in connection with two buffer storage tanks saves fuel resources in a special way and avoids CO2 emissions. A multi-generation house, a sports hall and more than 80 residential buildings are supplied with heat from renewable energies.

With the portal https://energiewendedörfer.de the University of Kassel and the Georg-August-University Göttingen present first results from the joint project "Innovative concepts and business models for sustainable bioenergy villages - climate-friendly, democratic, close to the citizens". In particular, concepts for bioenergy or biogas plants are being developed that can enable continued economic operation following the previous 20-year EEG phase.
With recommendations for action in the areas of residual material use, alternative energy crops, optimisation of value creation through recycling management, future electricity marketing, efficient heating networks and sector coupling of bioenergy with other renewable energies, bioenergy villages and operators of energy plants are shown possible new business models. To this end, the researchers are working in so-called real laboratories with the bioenergy villages Krebeck/Wollbrandshausen and Altenmellrich/Anröchte in order to be able to examine the feasibility and economic viability of the new models under practical conditions.
The platform https://energiewendedörfer.de offers recommendations for action as well as information on biomass and residual material potentials and a GIS map that presents the bioenergy villages in Germany and their measures and technologies. Among other things, this enables a targeted search for the fuels or substrates used and the technologies applied. It is aimed at all interested parties who are committed to an energy and heat transition in their villages or communities.
The CO2-In addition, attractive funding programmes and the Building Energy Act support local authorities in switching to a renewable heat supply. Extensive information offers on energiewendedörfer.de as well as the guides, market overviews and other service offers of the Agency for Renewable Resources (Fachagentur Nachwachsende Rohstoffe e. V. - FNR) provide the necessary information. (FNR) provide the necessary support to advance the energy transition in municipalities.
The joint project "Innovative concepts and business models for sustainable bioenergy villages - climate-friendly, democratic, close to the people" is funded by the Federal Ministry of Food and Agriculture (BMEL) via the project management organisation FNR. Information on the project is available at https://energiewendedörfer.de and in the FNR project database at www.fnr.de under the funding codes "22405817" and "22405218" available.
Further decreasing investment costs for PV, wind and electric storage expected: In this regard, the Agency for Renewable Energies (AEE) publishes a new meta-analysis today. It compares the investment costs reported in 15 studies for a total of 11 energy technologies, including offshore and onshore wind energy, photovoltaics and solar thermal energy. It also presents statements on the investment costs of storage technologies and heat pumps. "The meta-analysis shows that specific costs for wind energy and photovoltaics are expected to continue to fall despite the cost reductions already achieved.
Another piece of good news for the energy transition is that investment costs for storage technologies can also be expected to fall drastically in some cases," says AEE Managing Director Philipp Vohrer, summarising the key findings of the meta-analysis.
The Federal Institute for Research on Building, Urban Affairs and Spatial Development (BBSR) has published two brochures providing information on the ÖKOBAUDAT and WECOBIS portals.
