This doesn't give a complete answer, but according to Steam's Hardware and Software Survey, 31% of Steam's Linux users are using "SteamOS Holo". It's the name of SteamOS 3, used by Steam Decks. 2.57% of Steam users are using some Linux distro.
Modding might not be as easy as on Windows, but for example, Mod Organizer 2 works on Linux. Steam Tinker Launch helps with MO2 installation and usage. Wabbajack also works after some tinkering, but you'll need to search the Internet to figure out how to get it working.
I have recently played Fallout: New Vegas with Viva New Vegas modlist and Skyrim with Nordic Souls modlist under Linux. Took some tinkering to get the modding things working, and to figure out where each of the files are located, but other than those, the games worked fine.
Once you go through the pain of getting one modding tool working, you can then use it with other games without the initial hassle.
I am no expert either. But, as far as I know, the cut-off speed for wind farms is around 25 m/s. I assume that the maximum output is when wind speed is 25 m/s. 10,4 m/s is about 40 % of 25 m/s, which means that this power plant's average production is about 400 MW.
Some years ago, after a few failed attempts, I made the switch from Windows to Linux. I used Gentoo Linux on my computer for a few years. After that, I ended up switching to the Apple lands, and a couple of years ago back to Windows. Been thinking of switching back to Linux for a while, and thanks to the nonsense and sense that this year has brought, I am back to using Linux.
At first, I wanted to see how gaming is on Linux, and specifically on my machine. Figured the easiest way to do that is by installing Linux on an external SSD drive. I chose Linux Mint for that installation. Turns out, gaming is great on Linux nowadays. I haven't had any issues with the few games I have played. I was chosen into a closed beta of a game, and even that game works perfectly - even though it isn't even released yet. On Mint, I only had some audio problems outside of games.
I bought a new larger NVMe drive from Goodram IRDM (European manufacturer, btw) to install Linux on. I chose Artix, an Arch derivative, as my flavor of Linux. So far, I haven't had any problems with it. Windows still resides on my old drive in case I happen to need it for something, but I haven't used it after I installed Mint on that external drive.
You lose nothing by installing Linux on your old computer before buying a new one. If you don't like it, then go ahead and buy that new machine. Just remember to back up your files before you install Linux.
The short answer is: Yes. Both Java and Bedrock version of Minecraft can be played on Linux. Steam is available for Linux, and with Proton (let's just call it a feature of Steam) you can play almost all Steam games.
Linux Mint is a beginner-friendly stable distribution. Stable means that instead of updates being released immediately after becoming available, they are released after some kind of testing period. That means, that you don't need to worry about the system breaking because of some bad update, but it also means that you don't have the latest and greatest versions of the software. Some newer versions of software, especially newer kernel versions, can improve things like gaming performance. The kernel on Linux Mint lags behind several versions, but Linux being Linux, there are ways to install newer or the latest version of the kernel - or any other piece of software.
