Well those Intel CPUs used to thermal throttle anyway in their outlandishly inadequate cooling designs so they did not need to throttle power either way. Now they could throttle power but don’t have to

MacOS doesn’t need to throttle performance because ARM and other RISC architectures are naturally very power efficient

You can shut down or scale back energy/electricity produced from nuclear power plants as well by controlling the reaction rate. What would have been ideal was if nuclear had remained and the renewables took the production capacity share from fossil fuels

They shutdown half of their reactors temporarily for maintenance in 2022. It was a one time thing. Your statement makes it seem like they do it every year.
