Whereas GNOME so far made sacrifices to flexibility and power in order to improve usability KDE4 is succeeding in having its cake and eating it too. They merge flexibility with ingenious design to create a desktop environment in which having lots of options to choose from doesn't impair the ease of use and in some cases actually aids it."
Power management on computers has three parts: selecting devices that are more power-efficient, tuning your systems to run more efficiently, and configuring systems to use less power during periods of inactivity. Servers, desktop machines, and laptops usually need different power management schemes; there isn't a one-size-fits-all.
Anyway, some of you might know what PowerDevil is, some might not; well, for you who fear this is yet another attempt of threatening your lives, PowerDevil is a power manager for KDE4, and it won’t kill you. Credits to sandsmark for this beautiful name :D

Last week we reported that the open-source ATI Linux driver had picked up improved power management in the form of dynamic power management and power management profiles that can be defined by the end-user.
In Q4'07 we had looked at Ubuntu's power consumption with all of their Linux releases going back to Ubuntu 5.04. While Linux has improved in recent years when it comes to power efficiency and optimizations, more processes running on the desktop had canceled out any real power improvements.
The Open Source Technology Center (OSTC) at Intel has launched a Web site, LessWatts.org, to help Linux users maximize power savings. The site hosts several open source projects, and shares tips and tricks to help optimize power consumption on hardware from portable devices running on batteries to large data centers.
In part 1 of this series we learned how to measure how much power our systems are using, both hardware and software, and some tricks for reducing power usage without degrading performance. Today we're going to dive into the world of power management on laptops: ACPI, APM, hard disk spindowns, and spinups.
