Perhaps. Or perhaps what uses more over a lifetime is an ebook that is bounced around from device to device which all turn to toxic e-waste after a few years, constantly communicating with always-on servers for account data and DRM authentication hosted in a data centre based in a region powered by fossil fuels. All while a paper book just sits on a shelf causing no further environmental impact - potentially for hundreds of years.
To be fair, nobody’s preference for paper books or ebooks will change the environment in any meaningful way - the problems are much more systemic and require radical action from an unwilling corporate and political elite that has been ignoring the problem for decades.
Yay, happy hail Satan day everyone. I remember when Intel chickened out and rounded up their 666 megahertz pentium 3 processors to report as being 667 megahertz. Absolute cowards, no wonder China is kicking their ass.
