Computers are a crucial part of today's workplace, and they are major consumers of energy.
There are two simple steps that minimize unnecessary energy expenditure of computers. Power down your computer at night and over weekends. It requires less energy to boot up a computer in the morning than to leave it running all night. Set your computer energy savings setting to 15 or 30 minutes. This will shut down your monitor and hard drive if you leave your desk for an extended period of time, such as at lunch.
