Goodnight Computer – How to save money by logging off. PCs left on at night cost companies $2.8B a year

Your computer has an off-button. But if you’re like most people, you don’t use it very often. Maybe you like to leave certain programs or files open so that you can easily pick up working where you last left off. Maybe your computer’s start-up process is frustratingly slow. But leaving these devices on all the time is a problem. A typical desktop computer wastes almost half of the energy it draws, mostly in the form of heat. Turning a computer off when you’re done for the day — and utilizing built-in "sleep" or "hibernate" modes — can reduce the amount of energy consumed by 60 percent. Still, many employees prefer to leave their computers on all night rather than logging off and shutting down.
