Leaving computers on overnight = $2.8 billion a year | WHAT REALLY HAPPENED

Leaving computers on overnight = $2.8 billion a year

Admittedly I don't think much about it at all. I leave my laptop running overnight because I know it'll take five minutes or more to get things going in the morning -- not just booting up, but launching the various apps I start the day with, downloading my overnight email, filtering out the spam, and otherwise "getting settled."

But all the power wasted while computers are sitting idle overnight adds up, and one study has finally tried to measure it. The tally: An estimated $2.8 billion wasted on excess energy costs each year in the U.S. alone.

Webmaster's Commentary: 

Computers have various "hibernate" functions, but at least on Windows, they usually quit working properly after a while.

However, along with the waste of electricity, leaving your computers on overnight also shortens their lifespan. I know in the age of planned obsolescence where you buy a new computer every 3 to 5 years that might not seem like an issue, but as the economy tightens people will need to keep their computers far longer, and turning them on ONLY when needed will help.

Yes, constant switching off and on should be avoided, but turning everything off when you go to bed is a good idea to prolong the life of your equipment.

As for the long boot up time, I turn the computer on when I get out of bed, then go make coffee. By the time the caffeine kicks in, the system is ready to rock!
