The German parliament and the German government have decided to reduce the country’s greenhouse gas emissions by 2050 by at least 80%. Important additional milestones are to generate 35% or 80% of the electricity via the conversion of renewable energy sources by 2020 and 2050 respectively. Furthermore (later) it was decided to phase out nuclear energy conversion in Germany until 2022.

This transition of the energy supply system – in German: “Energiewende” – is in full swing. E.g. today 25% of the country’s electricity demand is generated from renewable sources (wind, solar, hydro and biomass). On the other hand the political discussion concerning in particular the distribution of the cost of the “Energiewende” is getting fierce.

From a technological point of view no principle problem hindering the transformation process has been identified. But the technological/economic optimisation of the transformation process is still an open question.

The talk will address: (i) cost reductions in electricity from renewable sources, (ii) market introduction strategies for energy from renewable sources, (iii) challenges in establishing smart grids (load and generation management, energy storage, upgrading of the energy distribution system), (iv) ideas for an optimisation of the future energy system of Germany and (v) visions on large area (inter-) continental energy supply systems.
