The EPA's ENERGY STAR® Computers program is a joint effort between the EPA and computer
manufacturers to reduce air pollution by promoting energy-efficient computer products. The EPA estimates
that use of ENERGY STAR® computer products can save computer users up to two billion dollars annually in
electricity costs. In turn, this reduction in electricity usage can reduce emissions of carbon dioxide, the gas
primarily responsible for the greenhouse effect, and sulfur dioxide and nitrogen oxides, which are the two
primary causes of acid rain.
Computer users can also help to reduce electricity usage and its side effects by turning off their computer
systems when they are not in use for extended periods of time — particularly at night and on weekends.
