Yes, as electricity only globally provides at best about 25% of final energy all this is misleading when it comes to the 'big picture'.

Usage profiles are indeed pertinent: Australians probably don't need dissipate energy in order for heating as Canadians do, but even this perspective isn't easy to grasp: heating thanks to gridpower is a thing in some nations without really cold seasons, France being one.

However the subject here is a gridpower-producing nuclear reactor, this IMHO sets a perimeter.
