Even after the EEG reform, most photovoltaic systems on buildings are economical to operate. sonnen GmbH from Wildpoldsried offers a "sonnenFlat". This is particularly interesting for those who already have a PV system and are thinking about adding a battery, but also for anyone planning to purchase a PV system in 2017.
On the following website you can have a look at the offer and the calculations: sonnenFlat
While two large providers are planning a merger, another company is entering the market in Munich with Oply. But it is still open when the city can actively promote the rental system.
Three years after the adoption of the 2030 Agenda for Sustainable Development, implementation is progressing, but not fast enough: worldwide, ambition must increase significantly to achieve the global Sustainable Development Goals by 2030.
Federal Minister Müller and Federal Minister Schulze will take stock of the implementation of the 2030 Agenda at the joint conference "Accelerating change - for a sustainable development worldwide and in Germany" on 5 November in Berlin. Together with Hajia Alima Mahama, Ghana's Minister of Local Government and Rural Development, and high-ranking representatives from civil society, business and academia, they will discuss how change can be significantly accelerated in Germany and worldwide.
Federal Environment Minister Svenja Schulze: "Sustainable development is not an elite project. Quite the opposite: people and nature should be better off in 2030, which benefits everyone. The shift towards an emission-free economy produces value added and jobs and can help innovations to make a breakthrough that are in demand worldwide. Ambitious sustainability policy is therefore our great common project for progress, and the 2030 Agenda is our compass for this."
Federal Development Minister Gerd Müller: "The world is looking to us when it comes to implementing the 2030 Agenda: as rich countries, we ourselves must set a good example - because people in developing countries are suffering from our way of consuming and from our lifestyle. One consequence is climate change, for which the industrialised countries are primarily responsible: We emit an average of ten tons of CO2 per capita. In Somalia, the figure is just 100 kilos. But the people in Africa, Bangladesh and many other developing countries are the main ones affected. We must and can make globalization just, change our consumption and our economy in a sustainable way, and thus preserve creation for future generations."
Despite positive trends and global efforts, progress towards achieving the 2030 Agenda and its 17 Sustainable Development Goals (SDGs) has been insufficient in many cases: for example, the proportion of the world's absolute poor has fallen from 26.9 per cent in 2000 to 9.2 per cent today, and child mortality in developing countries has been halved since 2000. At the same time, however, the number of people suffering from hunger has risen again in the last three years, especially in sub-Saharan Africa and South Asia.
The likelihood of limiting global warming to 1.5 degrees Celsius is diminishing, and over eight million tonnes of plastic waste continue to enter the oceans every year. At the next UN Sustainable Development Summit in New York in September 2019, heads of state and government will meet for the first time to take stock of the implementation of the 2030 Agenda. This summit has a crucial role to play; it should send the strongest possible political signal from heads of state and government for accelerated economic and social change.
With the new edition of the German Sustainability Strategy adopted in 2017, the Federal Government has taken a first important step towards SDG implementation in Germany and in the context of international cooperation with its partner countries. The Federal Government is currently updating this strategy in order to further strengthen the idea of sustainability in all policy areas. In the process, the suggestions of civil society, business and science are being actively taken up.
BMU and BMZ are flanking this with additional measures: BMZ supports developing countries and emerging economies in implementing the 2030 Agenda, BMU contributes with its International Climate Initiative. Both ministries are also striving to achieve climate neutrality for their buildings by 2020.
In 2015, the United Nations adopted the 17 Sustainable Development Goals of the 2030 Agenda. This showed that it is possible for the international community to join forces worldwide to tackle key challenges. These 17 closely interrelated goals have ensured worldwide that environmental, social and economic issues are thought of together and driven forward by all parts of society.

In recent years, many cities around the world have committed themselves to significantly reducing their greenhouse gas emissions by improving their heat supply, thereby making an important contribution to climate protection. Despite the energy transition, Germany is lagging behind in this endeavour because the energy transition primarily concerns the electricity supply. However, a "heat transition" is also necessary because it can be an important building block in the restructuring of our energy system if surplus electricity from renewable sources is converted into heat or stored. Local authorities with their heating networks and new neighbourhoods would be key players here.
The guide to the heating transition in municipalities was compiled by ifeu on behalf of the Heinrich Böll Foundation. It is aimed at anyone who wants to tackle the heat transition in their city or municipality and offers a compass for making the right decisions on climate-neutral heat supply.
With a very large majority, the municipal council decided on 22.07.2021 to initiate the urban development measure (SEM) "Nördlich Hafner". The development statute provides the project with a binding legal framework for the city of Constance and the remaining property owners in the area. The decision is also the conclusion of the preparatory studies (VU) that have been running for about four years, in which not only various subject-related studies and the urban development framework plan were developed, but also a comprehensive timetable and a detailed cost and financing overview were drawn up. In total, the development of the approx. 106 ha large area (of which around 60 ha settlement area) including all technical and social infrastructures (e.g. day-care centres, primary school). In the end, income from the allocation of land will result in a largely balanced overall balance.
"With the results of the preparatory studies, valuable foundations have been laid for a speedy development of the area and thus for the creation of affordable housing and commercial space. Even though major tasks still await us in the coming years: Now the development of the Hafner can really take off. I am looking forward to the further joint process of developing the new district for and with the people of Constance," says Construction Mayor Karl Langensteiner-Schönborn.
The development of the first construction phase could begin from the end of 2025, and the completion of all development measures in the third and final construction phase is planned for 2038. Until then, there are still many planning steps to be taken: Further owner discussions and negotiations (with the aim of acquiring the plots or a binding participation of the owners), the further development of the framework plan, in-depth expert opinions, the preparation of development plans as well as the development of an allocation concept for plots are only some of the tasks. For all those involved and interested, there will also be many opportunities in the coming years to inform themselves about the further process and to participate.
In 2016, the municipal council decided that preparatory studies for an urban development measure should be carried out for the Hafner area. After these were completed in May 2021, the project now reaches an important milestone with the consultations on the resolution of a development statute in July 2021.
Over the past four years, the city administration, together with external experts, has investigated the prerequisites for implementing an urban development measure in the area: from a planning, temporal, economic and property rights perspective. The preparatory studies have come to the conclusion that the urban development framework plan for the area, which was adopted by the municipal council at the end of 2019, can be implemented. "The important foundation for a rapid development of affordable housing and commercial space in the Hafner area - over 3,000 residential units and 15 ha of commercial space - has thus been laid," says Mayor Karl Langensteiner-Schönborn.
In contrast to traditional models of building area development, the instrument of urban development measures offers the possibility to prevent land speculation, to involve the owners in the development and to handle and finance the social infrastructure needs in the area through the measure. The instrument distributes obligations and rights fairly between the owners and the common good: investment costs are not socialised and development profits are not privatised, but reinvested for development.
The resolution of a development statute now sets the corresponding legal framework for the development. It is also the starting signal for the next steps in the development process. At the end of 2021, the decision to draw up the development plan for the first construction phase is to follow, and from 2024, the allocation of plots to WOBAK, housing cooperatives, building associations and other developers is to begin via concept procedures. Development of the first construction phase is expected to begin at the end of 2025.
