I am battling with the absurd power usage of ubuntu 11.04. On windows 7 (which came preinstalled) I can get around 4:30 hours turning everything off (wifi, bluetooth, lowest brightness for screen) with same settings I get 2 hours with ubuntu. I was wondering if I install xubuntu will that help me reduce my power usage?

Yes, but not on that scale.

To change your kernel to something that will increase your batter life, you need to use the kernel that is in the Proposed updates repository. For more on how to enable that, look here.

Yes, but almost definitely it wouldn't increase AC work hours by two times. Xubuntu has less tools and apps, and more optimized to be used in older, less powerful computers.

I don't think this is Ubuntu's fault. Battery life on a computer decreases over time. Ubuntu isn't going to steal two hours of battery life, I know this because I have a netbook which gets the same battery life as it did when it was running Windows XP. It is currently running Ubuntu.
