Energy scientist in Germany here. Germany could fully supply it's national grid with German energy production. We just don't do it because it's cheaper to buy i.e. heavily subsidized nuclear power from France, or other sources. In the end, it's all markets across the whole EU - by design. Why should it not be, the European energy grid is interconnected for a reason.
In 2010 I was paying 10 cents per kWh. In 2025 I am paying 36 cents per kWh. What ever happened in these 15 years, it is an absolute death spiral.
As a Germany energy scientist you should be very angry that right now according to ElectricityMaps.com Germany is emitting about 17 times as much CO2 per watt as France is.

Germany also has some of the most expensive electricity in the world. It is so expensive it is making some industries unprofitable. BASF, a major German chemical company, has implemented plant closures due to high production costs.
Most countries choose either cheap and dirty or expensive and clean for electricity but Germany chose expensive AND dirty.

We have enough fossil capacity that we don’t use for price reasons.
