Undoubtedly true, but I think you're missing quite a few
orders of magnitude there.

It wouldn't surprise
me to discover the energy consumption of just the servers in
Amazon Web Services datacenters exceeds the 1950s total, and
that's only AWS (reportedly more than 1.4 million servers).

https://smithsonianeducation.org/scitech/carbons/1960.html states
that, in 1954, there were 15 computers in the US.  That seems low
(did they only count IBM 701 machines?), but it reportedly went up to
17000 in 1964.

Even if you put the number of computers at 100 for the mid-1950s, at
100 kW each, you only get 10 MW of power when they ran (wich they often
didn't; due to maintenance, these early computers seem to have been
day shift only).
