The ongoing story of seconds on the taskbar

While I respect the desire to save energy, this feels a little bit like barking up the wrong tree. How much energy does it take to load ads in the taskbar and start menu? How much energy does it take to take screenshots every 3 seconds?

I had seconds on the taskbar for so many years now that I actually forgot it was added by "7+ Taskbar Tweaker" and not a native Windows feature.
