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 our energy grid, or that a miracle storage technology will somehow be invented in the next 10 years.
I can recommend "Sustainable Energy: Without The Hot Air" [1] by a Cambridge professor, it goes into great detail about the problems of matching electricity demand to supply day- & year-round.
