> Some of that energy becomes heat.

I'm neither for nor against, but on the physics here: basically all of the energy input as electricity is transformed to heat leaving a datacenter. Only a tiny tiny fraction is emitted as radiation (eg floodlights outside or light in fiber optics) or as kinetic energy (air moving away from fans/vents).

Computers are machines for turning electric energy into heat energy, plus some small useful side effects.
