NVIDIA says their new Blackwell GPU takes 2000 watts, and is between
7x and 25x more power efficient than the current H100, but that's
still a heck of a lot of power. Data centers have had to come up with
higher capacity power and cooling when each rack can use 40 to 50KW.

I mean, my entire house is wired for 24KW and usually runs at more
like 4KW including a heat pump that heats the house.
