About
Screen Savers... they don't save money.
Often including
complex images and graphics, screen savers generally do not save energy.
Screen savers were originally developed to prevent the permanent etching
of a pattern on older monochrome monitors. Screen savers would prevent
this by either blanking out the screen entirely or by displaying a constantly
moving image. Modern display screens do not suffer so much from this
problem so screen savers are mostly used for entertainment.
Buying
a new computer or monitor?
- If you
buy a new computer, consider a laptop. Laptops use only 1/4 the energy
of a desktop.
- If you
buy a new monitor, consider a flat screen (LCD). They use only 1/3 the
electricity of a traditional screen (CRT) - which make CRT's look like
watt hogs by comparison. They're small and slim, have a greater tonal
range (blacker blacks, whiter whites), are generally brighter than CRT
monitors and are flicker-free. They don't emit the kind of radiation
that makes some CRT users worry. They're also better for the environment
when thrown away: The mercury, lead and glass in CRT's is a is a disposal
problem and should not go into landfills. On the downside,
the initial cost for a flat panel monitor is significantly greater than
for the traditional CRT.
