I remember, not so long ago, listening to Microsoft explain to me how much power Windows Vista was going to save. To me...it sounded a lot like a long-winded discussion of how much power Windows XP wasted. So now, here we are again, and we get to talk about how much power Vista was wasting (and how much 7 will save.)
It looks, in fact, that the changes will be fairly minor. DVD ROM drives won't be spinning up as often, and Bluetooth connectivity will remain inactive until a device triggers it. Windows 7 solves an additional problem as well. Previously, many businesses instructed their employees to leave their computers on all night so that they could receive software patches that came in every few weeks. Windows 7 now has a power-saving sleep feature that can be remotely turned off in order to allow remote software updates.
This, of course, is only useful to corporate clients, though that does make up a pretty huge amount of PC power use. Using the ultra-simple tools available in Windows Vista, Continental Airlines was actually able to save about $2 M a year in electricity.
More or less power
