Analyse zur Transformation des deutschen Energiesystems von fossilen Rohstoffen zu erneuerbaren Energien als technologischer, stofflicher, und energetischer Systemwechsel Analysis of the Transformation of the German Energy System from Fossil Raw Materials to Renewable Energies Seen as a Technological, Material, and Energy System Change

The goal of securing almost 100 % of electricity generation in Germany with renewable energies (RE) and green energy imports is analyzed. The annual continuous load lines of the ways of generating electricity with RE demonstrate the actual supply capacity of RE as a function of the installed capacity. The increasing volatility resulting from the expansion of RE has a negative impact on the effectiveness of electricity generation and leads to high residual loads. It is not possible to compensate for this by storing the surplus electricity with hydrogen and regenerating electricity and importing green energy sources. A globally feasible concept of the complementary decarbonization of electricity generation from RE and fossil fuels via natural gas pyrolysis and the material-energetic use of lignite is proposed.
