"remaining coal",This sounds as if nuclear did produce the majority. But it never produced more than 30% of the electricity in Germany. In 2000 it was 60% fossil fuels and 30% nuclear. Renewables today produce 60% and fossil fuels are below 40% (coal only 20%). Of course, Germany could have decided to build more nuclear. It could have also decided to build renewables faster. Investing into renewables brought prices down by creating an economy in scale, which for nuclear never has worked. The result is that there are now immense investments into renewables worldwide.
