Just like how they stopped selling chargers for the sake of reducing e-waste. Even though they can save on shipping weights and charge extra for 1st party chargers.
Now is it worse for the environment to produce extra chargers and cables? Or the secondary purchases, shipping, and manufacturing? I can't tell you the actual impact.
Oh and remember the absolute trash 1A/5V charging bricks they included for the longest time ever? They hardly even pushed out 18w bricks before they nixed the entire included charger crap.
To save money, they can go the derelict laptop route.
If they get a low tdp board, maybe like an old laptop without a battery, the power difference isn't going to be too much. Pi can pull 9W at full tilt. And an old Ultrabook with it's monitor tuned off or unplugged can probably pull 35-45W at full tilt.
So 45W - 9W = 36W
36w x 24hr x 356 = 315,360Wh
315.36kWh x 0.25 cents = 78.84 a year
But that's assuming everything is running at full speed. For something running 24/7, we can probably estimate idle state is more common. Laptops can idle about 3-4W a pi4 is also idle around 3-4W.
So 90% at 4W and 10% at 45W for the laptop
And 90% at 4W and 10% at 9W for the pi
Gives us 8.1W average for the laptop
And 4.5W for the pi
Giving us a total difference of 31.536kWh. or 7.88 additional a year.
This is also assuming the laptop has the same computational power as the pi, which isn't true, so the laptop will end up finishing tasks faster than the pi and use more power for a shorter amount of time.
Zeal Zilent v2 62g are like MX Browns but better.
Brown's tactile is a little too little for me. Wanted blue's tactile but with the silent of browns. So I went Zilents.
