I don't go insane with it, but I usually use it to get to domain names, like search swagbucks for "NHL" instead of going to NHL.com

But since I started, I've gotten at least $200 in Amazon GCs.


We love Swagbucks, all our points go towards Amazon GC's as well...
 
If you use a CRT monitor, it would save energy. If you use an LCD monitor (as most people do today), it may actually use more. Even Google admitted this, despite the 2,000,000 watt hour "savings" claim.

Why would it use more?

It has to do with the way images on an LCD monitor are generated. Unlike a CRT, on an LCD monitor the LCD pixels aren't used to create the light we see. The monitor has a backlight that illuminates the entire screen, and the function of the LCD panel is to essentially block certain colors of light from passing through, allowing us to see the remaining colors. So, in order to see a white image, an LCD pixel basically has to do nothing, or be in an "off" state. But to see a black image, the same pixel is more or less at full power, blocking all light.

With that said, the increase in power consumption by viewing a black screen on an LCD monitor is really negligible. The bulk of the unit's power is consumed by the backlight, which does not change at all, regardless of the brightness of the image itself. One study concluded that LCD monitor power consumption can be improved by changing the brightness level of the monitor, which would make sense if doing so lowered the intensity of the backlight.

^^^ Yeah, with all the research I've done on TV's I should have figured that out! Makes perfect sense.

I have a plasma TV, and I chose plasma because of the constant backlight problem with LCDs. And how it prevents the screen from producing deep blacks.

I have been watching the marked and now with the local dimming LED LCDs I think LCDs will be able to produce as black of an image as the best plasmas eventually (I have a Pioneer).

The problem with the local dimming LEDs is that the dimming isn't local enough, but I think that tech will continue to improve.

Sorry, got a little OT there. :)
