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.

I've seen 10-12W easily on 4K for soc without av1. your soc (intel 11 gen) should support av1. try to play the video on mpv (with yt-dlp integration) with various hw acceleration options to see if it changes. probably your browser is software decoding.
for hardware decoding supported soc too I noticed 2-3W of extra power usage when playing youtube from website compared to mpv or freetube. the website seems doing inefficient js stuffs but I haven't profiled it.
Av1 will probably increase power usage. It's made to reduce data consumption
on mobile platforms nowadays power is more important than data. OTOH for servers bandwidth is more important.
