In addition to the motivation and background of the ecovillage movement, the film also gives a good impression of the Sieben Linden ecovillage.
The text on vimeoHow can a world beyond growth, competition and profit look like? The multimedia project "Degrowth in Bewegung(en)" shows which initiatives and movements develop and live social, ecological and democratic alternatives.
In the ecovillage Sieben Linden we met Christiane Kliemann, who tells us in an interview what makes an ecovillage, how ecovillages are politically engaged and where the relation to degrowth is.
Berlin, 22 October 2018: Vattenfall Energy Solutions, Gewobag and the energy storage start-up Lumenion are jointly piloting a new type of sector-coupled steel storage system at Bottroper Weg in Berlin-Tegel, which absorbs regional generation peaks from wind and solar energy in a grid-serving manner and later provides the renewable energy as heat and electricity in line with demand.
"With this pilot project, we want to demonstrate the particular technical and economic suitability of thermal storage systems for the effective utilisation of large quantities of wind and solar energy in a very practical way," says Alexander Voigt, founder and Managing Director of Lumenion. "Some of our team have been working with renewable energies for over 30 years and with energy storage systems for over ten years. Based on this experience, we made a conscious decision in favour of steel as a storage medium for the second phase of the energy transition, which is just beginning."
The Lumenion steel storage system stores "electricity peaks" for less than 2 cent/KWh in a cost- and space-efficient manner at up to 650° Celsius as heat, which can be converted back into electricity using a turbine unit if required - or used entirely as heat. As a co-founder of Solon, Q-Cells and Younicos, among others, Voigt has been successfully launching solar modules and storage systems on the market since the 1990s.
Hanno Balzer, Managing Director of Vattenfall Energy Solutions GmbH: "Decentralised systems and energy storage are key factors in the energy transition; heat is a particularly cost-effective form of storage. If the stored energy can then be utilised not only as heat but also in the form of electricity, that is a milestone. The high-temperature storage system brings us a big step closer to this!"
Karsten Mitzinger from Gewobag Energie- und Dienstleistungsgesellschaft adds: "The energy transition can only succeed if it is decentralised and based on partnership. As a housing industry, we are making our contribution to climate protection in our neighbourhoods. With this project, we are pleased to be able to demonstrate the good cooperation between energy supply companies, municipal housing associations and innovative start-ups. Only together can we master the major challenges of the energy transition."
In the Tegler pilot project, a 2.4 megawatt hour (MWh) storage block is being trialled for commercial use and transferred to regular operation. To this end, the unit will be integrated with an existing gas-powered CHP unit from Vattenfall Energy Solutions into the neighbourhood electricity and local heating supply of a 1970s apartment building owned by Gewobag. The storage system will temporarily absorb any power peaks that are not required and feed them into the heat supply later on as needed. In a second step, a reconversion into electricity is also planned.
Parallel to the construction of the pilot project, Lumenion is testing a 450 kWh prototype on the campus of the University of Applied Sciences (HTW) in Oberschöneweide. The HTW is supporting Lumenion with practical accompanying research in the development, testing and validation of data, as well as in the regulation and operational management of the innovative storage system.
In further projects, Lumenion storage systems with 40 MWh and even 1,400 MWh are to be created as the next milestones. These giga-storages can integrate existing and newly added large quantities of renewable electricity generation from wind and solar power into the existing grids in a particularly favourable, efficient and demand-oriented manner, thus enabling a significant acceleration of the energy transition.
Incentive to use less "grey energy" in the construction of non-residential buildings
The City of Hamburg promotes the use of wood for the new construction of non-residential buildings with a floor space of 100 m² or more.
The use of wood in the building construction of new buildings is being 800 € per tonne of wood product promoted.
In addition Insulation materials with the quality mark RAL-UZ 132 or 140 (Blue Angel) or the natureplus seal with a subsidy of 10,- €/m² component area promoted. At least 80 percent by volume of the thermally insulating building component must consist of the sustainable insulation material.
In an office building with 1,000 m² of heated floor space and solid wood exterior walls and ceilings, about 200 tonnes of wood are used. This would be eligible for funding of 160,000 €. The maximum amount of funding per building is 250,000 €*.
Billions from pensions are invested more sustainably and no longer used for fossil energies
Today, Thursday, the European Parliament and the Council of the EU officially announced their agreement on new EU rules for occupational pensions. Thanks to the persistence of Green shadow rapporteur Bas Eickhout, we were able to push through important demands in the final "Directive on the activities and supervision of institutions for occupational retirement provision". Currently, occupational pension funds across Europe manage [...]
Neighbourhoods with old buildings have a reputation for lively urbanity and are therefore extremely popular with residents. But new buildings can also develop this charm, as the large number of successful projects in this volume of the best of DETAIL series shows. Ultimately, it is a question of the mix of residential and commercial uses, of open spaces and offers for older and younger residents of different nationalities and different social structures: even in times of an increasingly digitally networked society, urbanity is expressed not least through diversity. In addition to surprising theses on high-density living, this publication presents refreshingly inviting project examples from all over the world that whet the appetite for life in the city.
