Because nuclear renewables replaced a lot of nuclear power, Germany was a net electricity exporter, but that turned around, and electricity consumption is down a lot.

Nuclear is not the only way to provide clean energy.

Then other parts of the economy. Electricity makes up a quarter of Germanys emissions. Gas boilers, combustion engines and so forth all emit a lot, but they are not something, which can be replaced with a nuclear power plant. That takes other systems like heat pumps, electric cars and so forth. Since that makes up most of the emissions changes in those areas matter a lot more then the electricity system.
