Schröder wasn't around in 1969 when the first contracts for russian gas have been closed.

> Heating could have been switched to heat pumps

We have 12 million gas boilers. Last year, we had an install capacity of 165k heat pumps. The government is trying to up that to 500k per year. Even in this (somewhat optimistic) scenario, that would be 24 years of work.

So yes, we need to start doing that. But until last year, we had 16 years of governments that did fuck-all for renewables.

Imagine if that was started on 2002 when Energiewende was voted, it'd be 4 years to go. That it takes a long time is never a good excuse not to do something, rather the opposite.
