Only 90 years ago, my mother grew up with kerosene lamps for lighting, no electricity. She was born in late 1926. Lighting in the countryside was so scarce that deer would act as Peeping Toms and come stare through the windows, scaring the crap out of her. As an adult, she craved light (and heat). So, no, she was never a good example about turning off lights. My childhood home, built in 1948-1955, was a tech marvel (some features would still be over-the-top) and much of its focus revolved around lighting & climate control. Remember, my dad was a genius (once whisked away by IBM for debriefing) electro-mechanical contractor and he doted on his wife, who was 16yrs his junior.
Funny story:
The city would come to my dad for (free) help laying out municipal power lines and water systems. As a result, the above-mentioned house had its own, dedicated 3-phase power supply while everyone else in the area had single-phase. In short, the neighborhood came to know that we had a special relationship with the city managers and utilities. Along came a big hurricane and knocked out all power (single & 3-phase) for 4 or 5 days. Afterwards the city manager called my dad and said they'd been catching hell from everybody demanding to know why our home was "lit up like an airport" while everyone else was in the dark. Answer: Army Surplus generator in the garage.
