This topic alludes back to a previous thread, found
here.
My friends and I were having this debate earlier today, whether it's better to leave your computer on at night by just putting into suspend/sleep/whatever, or turning it off. Considering the high number that was shown on my parent's last energy bill, we have decided to turn off all non-essential electronics at night time, even going so far as to unplugging the VCR's and TV when we're not using them (Apparently those still use small amounts of power even when not in use).
To sum it up, my friends leave their malarkey on at night, whereas I turn everything off, including the power strip, at night time. As Particle said:
Do you still plan on using your current computer in ten years? No? Leave it on.
But in regards to power consumption...how much will it be affected? What's the cost/benefit ration between power usage and computer life?
