Did the LLMs tell you that? It’s not hard to look up on your own:

Data centers, in particular, are responsible for an estimated 2% of electricity use in the U.S., consuming up to 50 times more energy than an average commercial building, and that number is only trending up as increasingly popular large language models (LLMs) become connected to data centers and eat up huge amounts of data. Based on current datacenter investment trends,LLMs could emit the equivalent of five billion U.S. cross-country flights in one year.
