Aside effects of the Ukraine war, it feels like the bill people actually pay has not risen too much in recent years. Germans famously do not have air conditioning in their homes and most switched all the lights to LEDs, leading to substantial bill reductions in many cases. Electricity for cars or for heating can be obtained at about 25% lower prices and modern houses are, in general, quite energy efficient. So I'd say that the high energy prices are hindering the construction of new factories/keeping the old ones (which can turn out to have bad effects soon), but everyday life is not too much bothered by them.

While that covers only the second half of 2023, the prices since then have come down significantly.

Germany was never cheap, it was and is still in the top 5. What you also need to consider in those charts, what is the average salary. While it is comparable to Italy, take a closer look to Hungary how expansive it is there.

This wouldn't change with nuclear energy because the price is bound to the most energy source.

There is a reason the energy companies still keep coal power plants. Without the price and profit would go down.

That's almost certainly just a benefit of brexit, if we were still in the EU we'd be paying the highest, without any competition.
