No, the wind and solar capacity is not massive, in fact it is far too small. If it were much bigger, you would have much lower prices. Electricity in Europe is expensive at the moment because of fuel prices.
Also, I don't have the numbers nearby, but I believe gas is mostly used for heating in Germany. Your heating system is outdated - you just didn't care because of the cheap gas from the east.
Stop blaming the technologies that can actually fix this.
