The best test I can come up with at the drop of a hat:

	Plug server into std. watt-hour meter.

	Run benchmark X, Y and/or Z for one hour.

	Note KWH's consumed.

This is so trivial a software house could do it if they
had an electrician buy the meter and wire it up with plugs.

It will tell you true KWH's, as that's what they measure. The
meters are highly tracable back to NIST/etc standards [1] and
they are cheap.

Radical idea: why not call The Donelan Test, and demand it from
your vendors? 

1] Want stds that have been beaten on? Use those proven by products
with lots of money changing hands.
