OpenAI yesterday announced[1] a partnership to deploy computer chips, but chose to denominate the size of the deal in gigawatts (instead of dollars, or some measure of computing capacity, or some measure of capability). They certainly seem to think about this in terms of electricity requirements, and seem to think they require a lot of it.

(I may have the units off a bit, but it looks like OpenAI's recent announcement would consume a bit more than the total residential electricity usage of Seattle.)
