The Aero Glass interface is what Vista uses to implement the pretty animated transitions and clear windows when switching between applications. Now, this could also be the reason why Vista has been draining laptop batteries faster. When Aero isn't active, it's been said that the battery consumption is comparable (if not better) than Windows XP.

A technologist from Hewlett-Packard John Wozniak has spoken about the inherent problem of the system, saying "They've really made it complex from a power management standpoint. The potential is there to do some good things, the bad thing is that it comes with the canned settings... and we didn't like any of them." This is a pretty common reaction because even Lenovo has done the same thing with their laptops.

Microsoft is unfazed by this. They are actually encouraging PC companies to customize the power settings saying "We actively encourage (PC companies) to customize the default power profiles so that users get the most out of their hardware." in their statement about the current "power draining issues" of Vista. Now, we have to remember that Vista had been marketed as being more power efficient before, unfortunately a lot of people feel that this isn't true and want more from the OS.

A lot of other distinguished people have spoken on the current problem and how they are addressing it. If you want to read more, you can see the full article via our read link.
