Generally, heating and cooling are the main energy consumption for domestic purposes. next up is the car, and then electrical consumption. (from what i remember).
I suppose it depends on where you live. Our house consumes something over 20 000kWh per year as our heating is also electric (and rest of the consumption is pretty neglible compared to heating) and we also have a fireplace which consumes around 15m³ of firewood, depending on how cold winter happens to be. Electric grid here has a ton of renewables and nuclear, so co2 footprint should be on the smaller side compared to global average.
Also, as google and microsoft (among others) shoehorns AI “answers” to everything that adds up, but private use seems to be quite insignificant anyways.
I think there already was case like this with either Google or Meta somewhere around Europe few years back. Or it might’ve been actual search results instead of extracts. The decision was overriden shortly as their web traffic dropped drastically. They’ll 100% do this and don’t think twice.
