Germany started out with a high amount of coal and lignite (as a domestic source of energy with many jobs depending on it). The carbon footprint dropped with the rollout of renewables according and will be very low once the transition to renewables is completed. It makes no sense to compare it to France, which switched to a nuclear a long time ago. This is relatively easy to understand in my opinion.

Shouldn't this so-called "transition" should be monotonic? The derivative of energy price should be always negative if you're right. It's not. It's very, very, very much not.

If the end state is very cheap energy, why is it the opposite of cheap now?

Look: the "energy transition" is not working. It's done the opposite of work. You have to concede to reality at some point.
