Because it is. You are brainwashed by the nuclear lobby trying to tell the fairy tale of how every plan without nuclear will fail and the fossil fuel lobby telling the tale of how it's hopeless and reducing coal isn't working. And both just tell you the same lie about some magical increase in coal use in Germany that doesn't exist.

The idea above is basically the epitome of cluelessness and just parroting narratives. Nobody is freezing in winter because there isn't enough electricity. Because the amount of heating via electricty is low and nobody is heating with coal either. That what gas is mainly used for and why people are talking about gas storage... and no, that doesn't have much to do with electricity either as gas use in electricity production is also low and only used as a peak burner to adapt to quick changes in demand.

It's one big ball of lies while conflating primary energy, heating and electricity to disguise that the underlying facts are already false.
