Maybe you should read what I actually wrote before you go shouting WORNG
everywhere.
I never mentioned the same CPU working harder under Vista - my point was
that on a modern PC with a later model of processor (remember the vast
majority of home user sales of Vista are by OEM - the retail market is
insignificant, so they are getting Vista on a newer PC with a newer
processor so your comparison is only valid for tiny fraction of the vista
users out there) that can be more powerful in terms of processing capability
it will actually draw less then a previous generation of processor.
The latest generation of Intel CPUs will have a 2W mode as well for
extremely low power usage scenarios.
Again more modern device will run in lower power modes even with low
priority services such as indexing are running, again the default time for
defrag and update are in the middle of the night when your PC will be idle
and drawing a fraction of the power during full operation.
