I mean there's a law for coal power in Germany, already since decades but the new add-on codifies that. They might be doing worse than France in terms of CO2 emissions per capita but far better than the US.
Since cost is mentioned:
"The cost of generating solar power ranges from $36 to $44 per megawatt hour (MWh), the WNISR said, while onshore wind power comes in at $29–$56 per MWh. Nuclear energy costs between $112 and $189."
