Save yourself the fcing annoying Phoronix layer ads, and nine ad filled pages. (They really need to get their content-to-ad ratio above one.)

Conclusion:

Quote:

With similar workloads, for the most part the power consumption is comparable between Ubuntu 11.04 and Windows 7 Pro SP1. The only major differences came during Flash-based HD video playback being more efficient under Windows, power consumption while OpenGL gaming, and in select other areas. Ubuntu / Linux actually has the potential to become more power efficient than Microsoft Windows 7 based upon the close findings from today. Once Active-State Power Management (ASPM) is properly fixed up for Linux, there is still a Linux 2.6.35 kernel power regression, a scheduler power regression, and more.

For sandybridge users ubuntu currently has power usage problems. Its something to do with the graphics drivers. 11.10 used 10watts more on my system compared to Win7 (25w vs 15w).
You can set the i965 rc6 boot setting to get round it but you might get graphical glitches
