No, they don’t. The increase on electric consumption is because of another factor in your house. If family is on summer vacation that could be why. Sometimes people forget that by virtue of having free time, they spend more time inside and generally use more gadgets, items, electronics, etc. for entertainment. That do increase the electricity use. A working and studying family spend over half of the day elsewhere. That’s halve of the same electric use as a family that’s watching tiktok, playing videogames and watching TV inside the whole day.
