I don't

But where you live does matter. Average monthly household energy usage in the EU is 200-400 kWh. In the US it's more like 800-900kWh. So what you consider "normal energy usage" may vary considerably by where you live.

At 200-400kWh total usage, 30kwh starts to look a lot more significant. So you should at least consider the possibility that it's not that energy usage from AI is insignificant, but that your existing energy usage is wasteful.
