I buy kindle books, then periodically I vacuum the books into calibre as a backup.
I don't want dead trees anymore. I want nicely formatted ebooks so I can give away my quarter ton of dead trees & shelves. my DRM-free ebooks are nearly weightless!
According to one lifecycle analysis of printed books versus e-readers, the energy, water, and raw materials needed to make a single e-reader is equal to that of 40 to 50 books. In terms of the effect on the climate, the emissions created by a single e-reader are equal to roughly 100 books.
If you read 100 books on your e-reader before upgrading it, the effect on the climate is no different than reading those books in print.
@sandbag_attitude I have no idea what other people are like. But I am made to be a scholar by trade, I just happen to be a programmer because life worked out that way and I like it.
I read *very* fast, high retention, and can generally synthesize it fairly well after the fact. Ebooks are a very effective investment for me, if the ereader tech is adapted for serious readers.
@pnathan I swear by my Kobo aura one. https://us.kobobooks.com/products/kobo-aura-one The screen is big enough, even that you can read PDFs without having to resize them from paper-dimensions. Supports epub + mobi, and you can manage the collections from Calibre without jailbreaking it. I think all the kobo products are similar.
