wat DOES it cause besides money?If i leave electricity hanging on like my computer,...would it cause environmental problems? wat DOES it cause?Most electricity in the U.S. is produced by burning coal, which is extremely polluting. So the more electricity you use, the more coal as burned -- and the more pollution is caused. So using less electricity doesn't just save money, it prevents pollution, too.
The best way to save electricity with your computer is to set it to Sleep/Standby automatically when you're not using it.
In Windows XP go to Start %26gt; Control Panel %26gt; Power Options
On a Mac go to System Preferences %26gt; Energy Saver
