From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

For example when watching 1080p youtube video in Safari the power consumption is only 0.1watt because it's using hardware decoders. (not including display backlight, I can't measure it). But when I play the same video in firefox which is using software decoding the consumption is around 0.7w which is not as good as hw decoders, but still less than a watt
