Very true. I visited New Delhi in December and noticed how heating/AC wasn't built in to the buildings yet it felt normal to just bundle up/unbundle up depending on the temperature. Getting rid of boilers and only boiling water when you need to is another approach that helps with energy cost - especially if they get smarter and can predict usage (on in the mornings, off when people are out of the home, etc).
