You might think you'll be right back when you leave your room with the lights, computer, and fan on, but who knows what kind of distractions are waiting outside your door? If you get sucked into a movie marathon with your sister you could forget all about the energy the lights and other electronics in your room are using. Even if you're positive you'll BRB, flick the switch. It's easy enough to turn back on.
