Thanks for catching, you are right that the average USA home is 10.5MWh/year instead of kWh. I was mistaken. :)

Regarding the remainder, my point is that the scale of modern frontier model training, and the total net-new electricity demand that AI is creating is not trivial. Worrying about other traditional sources of CO2 emissions like air travel and so forth is reasonable, but I disagree with the conclusion that AI infrastructure is not a major environmental and climate change concern. The latest projects are on the scale of 2-5GW per site, and the vast majority of that new electricity capacity will come from natural gas or other hydrocarbons.
