1)You forget the energy efficiency / less energy consumption part

2)You forget the demand-response and energy storage part

3)" it will be extremely expensive to cover all these power requirements in renewables only" ; a lot of existing power plants are old would had been closed anyways... and renewable are becoming the cheapest new capacity, so I don't seen the extremely expensive part

I am not a big fan of this German "energy transition"... but often I find sloppy the critics addressed to this transition
