Can you put that in some perspective with just an order of magnitude? Somehow it feels like next to auto or plane travel, or consuming beef - audio playback of any kind would seem like it isn't very significant.
Hmm actually I wonder now if this was a joke and I just got suckered.
No, Benn Jordan got into that a while back. It's not the listening part, it's the manufacturing that isn't 'green', though I'm not sure quite how the math works: for instance, whether they're counting the trucking of boxes of vinyl circles all over the place rather than just uploading bits locally. Some of that would apply to CDs, too, but CDs are about as relevant as vinyl records are.
But the vinyl blanks for this device have to be manufactured, with similar processes to the vinyl for professional releases. Also, cleaning the disk after you cut it, hoovering up the swarf etc. is surely more energy efficient when done in bulk in a factory? Factories use more energy than a home device, but when divided by the number of units produced?
