Can I get away with building less power infrastructure if I go with a smaller number of heavily-upgraded rooms vs a larger number of non-upgraded rooms?

Upgraded rooms require more power. (Source)

However, you will indirectly use less power by using a smaller number of heavily-upgraded rooms, as you will need fewer dwellers to man them (requiring less food/water -> requiring fewer food/water rooms -> using less power).
