Earlier quoted context omitted.
Solar and wind alone won't work without support by gas or other non-renewable sources. Try to find a single scientific study that gives a detailed overview of how the German energy mix is supposed to work and that explains how supply will be matched to demand 24/7 all year round. None exists. The whole "Energiewende" is built on the hope that either our neighbors will produce the necessary base capacity to stabilize…
And somehow the cost of the non renewable energies that are required to deal with the volatility of wind and solar are never factored in the cost.
If that sounds idiotic to you, that's because the change in the EEG was created to make exactly this impossible.
