“…One reason for the high proportions in these clusters could be the existence of a critical mass of innovators (cf. Deutschle et al 2015), but such aspects could not be included in this analysis. On the other hand, however, achieving the goal of energy autonomy is all the more difficult, the more inhabitants a municipality has.…”

Alone the number of terms for this concept illustrates the diversity within the literature, which also extends to its definition.…”

Developing a municipality typology for modelling decentralised energy systems

2019

The recent rapid expansion of renewable energy capacities in Germany has been dominated by decentralised wind, photovoltaic (PV) and bioenergy plants. The spatially disperse and partly unpredictable nature of these resources necessitates an increasing exploitation of integration measures such as curtailment, supply and demand side flexibilities, network strengthening and storage capacities. Indeed, one solution to the large-scale integration of renewable energies could be decentralised autonomous municipal energy systems. The achievement of grid parity for some renewable energy technologies has strengthened the desire of some communities to become independent from central markets. Whilst many communities in Germany already strive for socalled energy autonomy, the vast majority do so only on an annual basis. Several studies have already analysed the technical and economic implications of the mainly decentralised future energy system, but most are restricted in their insights by limited temporal and spatial resolution. The large number (11,131) of German municipalities means that a national analysis at this resolution is not feasible. Hence, this study employs a cluster analysis to develop a municipality typology in order to analyse the techno-economic suitability of these municipalities for autonomous energy systems. A total of 34 socio-technical indicators are employed at the municipal level, with a particular focus on the sectors of Private Households and Transport, and the potentials for decentralised renewable energies. The first step is to scale the indicator values and reduce their number by using a factor analysis. Several alternative methods are weighed against each other, and the most suitable methods for the factor analysis are chosen. Secondly, selected quantitative cluster validation methods are employed alongside qualitative criteria to determine the optimal number of clusters. This results in a total of ten clusters, which show a large variation as well as some overlap with respect to specific indicators. For example, one cluster contains all major German cities and has a low potential for renewable energies. Another cluster, on the other hand, contains the municipalities with a higher potential for renewable energies due to their high hydrothermal potential for geothermal power. An analysis of the municipalities from three German renewable energy projects "Energy Municipalities", "Bioenergy Villages" and "100% Renewable Energy Regions" shows that in eight of the ten clusters municipalities are aiming for energy autonomy (in varying degrees). It is challenging to differentiate between the clusters regarding readiness for energy autonomy projects, however, especially if the degree of social acceptance and engagement for such projects is to be considered. To answer the more techno-economical part of this question, future work will employ the developed clusters in the context of an energy system optimisation. Insights gained at the

“…Both systems assume that 100 per cent of energy demand is satisfied from local resources. The former, also named autarky "on balance" [24,27], on grid [27,28], or grid-connected [27][28][29], is defined as the ratio between the locally created energy supply and the local energy demand. The energy is fed into an energy grid (e.g., the electricity grid) and provided for consumers on demand.…”

“…Energy production and consumption are asynchronous and separated; thus, there are both supply surpluses and supply shortages. In turn, absolute self-sufficiency (or off-grid, grid-alone, strong, or physical) assumes a lack of external energy recipients and suppliers [24,[26][27][28]. The time lag between consumption and production is limited by the local energy storage infrastructure, and the processes are more synchronized and balanced "on the spot."…”

“…Deutschle et al [24] refined the main strategies into an open-ended list of the goals of energy sustainable systems, including autarky, such as energy, resource, and cost efficiency; climate change neutrality; and renewable energy sources. A sustainable energy village should be evaluated with all these criteria and the degree to which it meets the requirements defined by its goals.…”

Sustainable Energy Autarky and the Evolution of German Bioenergy Villages

The concept of an autarky has a long history and meaning related to its negation and unpopularity. In liberal schools of economics, autarky is usually considered from the perspectives of economic trade protectionism, closed economies, and threats to welfare. Nevertheless, the concept of autarky has gained a new meaning, understood as the local utilization of renewable energy resources from the perspective of their inter- and intragenerational distribution. Local action is shaped by the global perspective. This research consists of three steps. First, a model of energy autarky has been offered based on the system theory. The model shows the variety of the structures and features of energy systems offered in today’s debates on energy autarky. Second, the key postulates of sustainable development have been presented to define an autarkical sustainable energy system. Finally, the concept of bioenergy villages in Germany has been presented to illustrate the approach to energy autarky. The research shows that the concept of autarky and single solutions, such as the use of renewable resources, are not themselves a success from the perspective of sustainable development; this misunderstanding is well illustrated by the evolution of the German concept of bioenergy villages into smart villages.

Auswirkungen des Austausches einer Gasheizung gegen eine Außenluft‐Wärmepumpe im EFH

Der Gebäudebestand benötigt rund 30 % des gesamten Endenergiebedarfes in Deutschland. Der Erfolg der Wärmewende hängt daher maßgeblich vom Einsparpotenzial im Gebäudebestand ab. Dazu gehört neben der Sanierung der Gebäudehülle auch der Einsatz einer klimaneutralen Wärmebereitstellung. Für dieses Ziel ist es vorteilhaft und notwendig, die Anlagentechnik von fossilen auf erneuerbare Energieträger umzurüsten. Derzeit gilt zu Recht die Wärmepumpe als Schlüsseltechnologie für das Gelingen der Wärmewende. Dieser Beitrag untersucht den Autarkiegrad der Kombination Wärmepumpe mit Photovoltaikanlage genauer. Um den Autarkiegrad bestimmen zu können, wird für ein konkretes Praxisbeispiel eine Simulationsrechnung mit dem Programm PV*SOL erstellt. Als maßgebend für die Auswertung wird der lastgerechte Autarkiegrad in Abhängigkeit der damit verbundenen Investitionskosten bestimmt und dargestellt.
