That’s simply false. Germany’s emissions have been on a steel downward trend year after year since the start of the energy transition.

The temporary switch to coal has only temporarily slowed down the pace of this decrease.

> Peak demand is winter and during the night. Solar is unable to meet those needs so in moving away from oil they have been burning coal instead.

The two months where renewable electricity generation peaks are January and February, exactly in the winter when most necessary.

It is true that solar output is lower in winter. But at the same time, wind output is highest in winter, and that has a stronger effect on the cumulative renewable output.
