So how did people use the internet in the good old pre-web days? There was email, of course, and FTP, and also a bunch of other interesting protocols. If HTTP and HTML hadn't come along, we might just have enhanced Gopher instead. Many of the pre-web protocols are still in active use, but sometimes it's only nostalgia that keeps them going. Try typing finger email@example.com at the command line to see how blogging works using steam technology."

Worldwide, that's 868 billion kilowatt-hours per year. The total includes the energy used by desktop computers and monitors (which makes up two-thirds of the total), plus other energy sinks including modems, routers, data processing equipment and cooling equipment."
