Lo and Behold...Green Computing is here to stay.
By now, it is very likely you have your ears full with slogans like "Save Power", "Save Water", "Save Rain Forests"; oh the list goes on and on...
Why the outcry? The resources in this world are limited. Human race just seem to be inventing reasons to consume these limited resources and before long we could wake up to find everything gone!
Green computing is the study and practice of how to use computing resources efficiently. What are computer resources? Hardware, networks, people make up the computing systems that you and I are so much involved with. Due to the fact that there is an immense growth in the usage of computers the world over, the energy consumption levels have also risen to dramatic heights. Not only the number of computers, but also how they are used also accounts for the rise of energy consumption. Just how much energy does a computer consume? An interesting question indeed, which also carry an equally interesting answer.
A typical desktop PC system is comprised of the computer itself (the CPU or the “box”), a monitor, and printer. Your CPU may require approximately 100 watts of electrical power. Add 50-150 watts for a 15-17 inch monitor, proportionately more for larger monitors. The power requirements of conventional laser printers can be as much as 100 watts or more when printing though much less if idling in a “sleep mode.” Ink jet printers use as little as 12 watts while printing and 5 watts while idling. And lets do some math!
Total Cost per device per day of 8 hours
= watts consumed x number of hours x unit cost of electricity
(100 + 150 + 100) x (8) x (local rates)
Although the amount is dependent on local electricity rates, this would have to be multiplied by the number of devices and also by 365 days to calculate the annual cost. This would most likely to be a staggering amount. Green computing advocates methods in which you can lighten the load on your wallet. Approaches to green computing involve:
- Power management
- Power supply
- Material Recycling
The article titled Green Computing Guide, from the University of Colorado talks about why it is important to focus on green computing, the advantages of making your IT infrastructure more greener as well as methods in which you can do so.
Like in everything else, being aware of the matter and being conscious of your surrounding helps a lot in putting wrong to right. Needless to say, little things always make a big difference :-D
Go Global Go Green!!
