Saving some green…with greener computing. Bloomberg Boot Camp, a report on today's technology. Having your computer or computers running day and night….may make it convenient….when you need to quickly jump on the Web…or type up a document….but it can be costly. The average computer uses about a hundred watts of power while it's operating. A company called Verdiem has made a business out of helping customers cut the power consumption costs of their computer networks. CEO Kevin Klustner..

"PCs consumer about 600 kilowatt hours a year of electricity. That represents about 50 to 60 dollars per year in terms of an energy bill. They waste almost two thirds of that energy in the sense that people aren't sitting in front of them when they're on. 90 percent of the end users leave them on all the time. And so there's a real opportunity to save energy and money by turning them off when they're not being used. And so our product called Surveyor, actually provides a very cost effective and quantifiable return on investment whereby we save 30 to 50 percent of the energy consumed on those PCs over the course of a year."

What can you do at home? You really don't have to turn off your computers….

"If possible, if they're available, use the energy settings that are on the PC and move the PC into a sleep or hibernate state. You don't necessarily have to turn them off. Moving them into a sleep or hibernate state will get you 90 percent of the savings without the hassle of having to reboot it every morning or every time you want to use it."

You can find the settings under power options…in the Windows control panel. Bloomberg Boot Camp, I'm Fred Fishkin.
