It's as much about competition and marketing as anything else.

Yes, efficiency factors in just like having a portable operating system platform definition has its benefits, but making money and marketeering factor in, too.

If a vendor lock-out or a vendor lock-in exists or can be created, it will almost certainly be used in a competitive situation. And these may or may not be green -- there have been examples of so-called green initiatives that have been inefficient, wasteful, energy-intensive or polluting.

Eco-friendly has turned into the antiseptic hand soap or the latest in the colored-ribbon-for-something marketeering. Usually with just enough of a fig leaf involved to avoid charges of crass commercialism.

"Oh, how can so-and-so be against [insert strawman]?"

So what percentage of power would be reduced by, say, solid state disks replacing mechanical disks, or by better-integrated water cooling or other technologies into new systems. The vendor marketeering of late often focuses on the processors, but where's all the power really going inside a typical computer?

Spinning down disks, or moving to more efficient technologies, or approaches such as the efficiencies gained from shared infrastructures -- bigger fans or power supplies at efficient loads, for instance.

And then there are the occasional design "surprises." Halting a processor can require more power than running it an idle loop, for instance.

If there's a straw-man argument that you can raise in marketing, you can bet it will be used -- something that allows you to characterize another organization, entity or product as inferior, wasteful, evil or any other currently-derogatory term. This is all basic marketing.

Pardon my cynicism.
