CO2

The Department of Energy estimates that in the average home, 40 percent of all electricity used to power home electronics is consumed while the products are turned off. What are you going to do about it???

"Tweaking can pay off. Annually, my desktop PC is now using 73 percent less energy — saving me $119 a year and depriving the earth of 1,405 more pounds of CO2."

So why dont we do something about it, start saving some energy?
