•While screen savers served the useful purpose of preventing
pattern etching on older monochrome monitors, the value is diminished on
modern monitors. In fact, the U.S. Environmental Protection Agency's (EPA)
ENERGY STAR program states, "Certain graphics-intensive screen savers
can cause the computer to burn twice as much energy." Here are the
facts. A screen saver displaying moving images consumes just as much
electricity as an active PC. A blank screen saver is slightly better, but
most screen savers don't save energy unless they actually turn off the
screen, or in the case of laptops, turn off the backlight. The key takeaway:
Your screen saver is offering no energy-saving benefits and may actually be
doing more harm than good. So if your screen saver is running, it means your
PC is inactive and should therefore be placed in a lower power state.
