>  This statement has permeated the industry and led to people accepting
lower levels of efficiency at part load in the hope that their PUE will
improve as the load increases.  There is no technical reason why PUE has to
suffer at part utilization, other than people accepting a facility design
that allows this.

Applying an analogy... if this were the case then you should also expect
the same economy from a 6.0l V8 as you get from a 2.0l four in the same
car. But the world doesn't work like that.

Unless its *very* modular and you can totally turn off the bits you are not
using then you simply can't expect a half used facility to have the same
efficiency as a fully utilised one half the size. Going back to the analogy
modern V8s have cylinder deactivation that saves some of the overhead, but
they still waste energy spinning a few extra cranks and pistons about that
they don't need 99% of the time.
