I've heard that e-books are better for the environment, but are they really?

Well, it depends on how you read them. If you read an e-book on a tablet or phone, then yes, it is more energy efficient than printing and shipping physical books. But if you read an e-book on a laptop or desktop computer, then it uses much more energy to power up your computer, run the software, and display the book. So there's no one answer here.
