Hi welcome to my series on how to start loving Windows 11 now that it's time for Windows 10 to say bye šŸ‘‹šŸ». Until 14th of October I will explore Windows 11 features and functionality šŸ’—.


In the eight blog post in my series on how to fall in love with Windows 11Ā I just want to helpĀ you save the world šŸ˜‡šŸŒ. And how can you help save the world?Ā By lowering your carbon footprint of course.Ā Let Windows 11 help you with the energy recommendations to make sure you use your computer in an efficient way. Lets reduce your carbon footprint!

Why does it matter

But why is it important to care about lowering your carbon footprint? Let's face it we are all on this earth together and how we live today will shape the future for our children and upcoming generations. By making conscious choices we can make sure the earth is a pleasurable place to stay šŸ’š.


There are several different waysĀ we can improve our carbon footprint,Ā one of them being how to use our laptops. Of course,Ā this is just a small piece of the carbon footprint cake and most of the carbon footprintĀ when it comes to our computersĀ actually comes from manufacturing laptops. But besidesĀ not changing your computer or phone yearly there are small things we can do.


How can you lower your carbon footprint with Windows 11?

You reach the carbon footprint settingsĀ by navigating to Setting > System > Power & battery > Energy recommendations.

There you will find a bunch of different settings.Ā Some of them will probably already be turned on and some of them you will have the possibility to easily click the apply button.Ā If you want to go wild you can click apply all in the top.Ā Microsoft are really good at creating a little gamification vibe by showing you a percentage on how green you are (I feel guilty because I'll never reach 100% šŸ˜†).


When you click apply on any of the settings they just apply, if you want to change it back afterwards you can click the title of the setting,Ā and you will navigate toĀ the correct sections in the settings to change it back.


The different settings

Let's take a look at different possibilities we have today from top to bottom:


All the available energy recommendations settings

Set the power mode for best energy efficiency:Ā This makes sure that the powerĀ and batteryĀ is being utilized in an efficient and good way on your laptop.


Turn on Dark mode:Ā Did you know that dark mode is actually more environmentallyĀ friendly because it uses less light on your screen.Ā This is one of those settings IĀ just cannot handle, I'm a bright girl šŸ’…šŸ»šŸ˜‡.


Set the screen brightness for best energy efficiency:Ā Let your screen brightness be adjusted after Microsoft's recommendations.


Put my device to sleep after three minutes: With this setting your device will go to sleep after 3 minutes of inactivity. This is just too little time for me who enjoys staring into the void and think haha.


Turn off my screen after 3 minutes: Similar to the setting about putting your device to sleep but a little smoother option if you still want to make sure your computer isn't using more power than needed.Ā 


Turn off HDR to conserve energy:Ā Since I use my work laptop for work the standard recommended settings for the screen areĀ sufficient for me. If you are using your laptop,Ā for example watching high quality videos or gaming maybe this is something that you need to think about.


Save power by optimizing screen contrast and brightness for the content shown: Make sure that whatever you're doing on the screen isĀ being utilized withĀ the best kind of settings, some activities require more contrast and brightness others less.


Change brightness automatically when lightning around me changes:Ā This is a good and flexible setting making sure that the screen has different brightness dependent on if you're in a light place or in a dark place.


Turn on dynamic refresh rate to conserve energy: Let your computer decide the screen refresh rate. Like I said, I'm using my laptop for work meaning that I don't use it for high quality video or gaming. This means I don't need my screen to refresh at a very high pace,Ā using this dynamic setting makes it easyĀ for my laptop to adjust.


Turn off my screenĀ saver:Ā Well nobody needs a screen saver even though I really often miss that Windows 98Ā cool maze if you remember that one šŸ˜†.


Stop USB devices when my screen is off to help save battery: Yeah,Ā you don't need those USB devices have a connection to your device when you aren't using your device.


There are a few mor ways to make sure you are doing your best energy wise, here you can read more about choosing energy efficient sleep settings: Power settings in Windows 11 - Microsoft Support.

My thoughts

SomeĀ settingsĀ you will really like,Ā some you will get used to and some you probably don't want to get used. But I think that this is just a very great way to get started and get you thinking about how different settings can help you lower your carbon footprint. I'm pretty pleased with my 80% and maybe one day I'll finally cave in and start using dark mode šŸ–¤.

Tried out Nano Banana 2Ā for generating images from text descriptions. The updated version feels more responsive and the output quality has improved noticeably. Works well across different styles from photorealistic to illustrated.

I have noticed that digital experiences often influence attention in ways that are difficult to recognize at first, and https://pin-up-official.com.in/Ā became one small reference point during that observation. What interested me was not the platform itself, but the way visual movement, timing, and interface structure can affect concentration. Sometimes I found myself following details more carefully, while at other moments my attention moved naturally from one element to another. It reminded me that focus is not always fixed and can adapt quickly to different environments. In the end, the experience became less about digital activity itself and more about understanding how easily perception responds to rhythm, structure, and changing stimuli.
