This only covers modern consoles but itd be great if there were a list for retro consoles like this. I am guessing that a Model 1 Genesis attached to a Model 1 Sega CD along with 32X attached all with their own power source probably isnt the greenest way of playing video games
I have to imagine the GBA SP (along with the AGS-101) has to be at the top of the list for game systems that contribute the least to climate change and do the least damage to your electric bill. I rarely have to charge mine. especially because I keep it in dim mode. the obvious factor here with the portables is that a seperate big ass monitor isnt involved.
the GB Micro is probably even better than the SP I imagine
