Veröffentlichung Archetypes of a 100% Renewable Energies Power Supply(2014) Lehmann, Harry; Nowakowski, MarkOn the way to a low carbon or even carbon neutral society there are a number of possible paths depending on political and social priorities. The German Federal Environment Agency has therefore been analyzing several "archetypesŁ of a future RE-based power generation. Three radically different scenarios were developed in order to study the technical and ecological feasibility of Germany switching to an electricity supply based entirely on renewable sources by 2050. Apart from different generation structures, the studies assume different degrees of connection and interchange between regions in Germany as well as between Germany and other countries within a Pan-European network.With the "Regions NetworkŁ scenario it has been shown that a 100% RE-based power generation is technically and ecologically feasible (English short version: http://www.umweltdaten.de/publikationen/weitere_infos/3997-0.pdf). Here, all German regions make extensive use of their RE potentials. Energy efficiency compensates for the rise in consumption caused by economic growth, e-mobility, and the use of heat-pumps. The introduction of large-scale electricity storage such as Power-to-Gas and the utilization of demand side management potentials plus a well-developed national electricity transmission grid make substantial contributions to the balancing of load and production. The system dynamics between supply and demand were minutely analyzed over 4 consecutive years.
In the "Local Energy AutarkyŁ scenario, small-scale decentralized energy systems use locally available RE sources to satisfy their power demand without being connected with each other or outside suppliers, i.e. without electricity imports to Germany.
The "International Large ScaleŁ scenario addresses the question whether and to which extent a wider network reaching across Germany's borders can be beneficial in terms of the optimal use of REs, the large-scale balancing between fluctuating RE feed-in and load, and using storage potentials.
