While this is close to true, it's not quite true.

This is largely because electric heat is generally distributed among
the various rooms, whereas computing heat is concentrated where the
computers are.  Since heat generally does not flow very well from room
to room, this means the machine room is over-heated, leading to
inefficiencies.

Of course, if the factors combine such that the big resistor under the
window is still drawing power even in the machine room (or machine
rooms), _then_ you're right.
