Now you are surfing the internet; facebooking, twittering, blogging, sending mails etc. You will be happy that you are not harming the environment; no paper, no cutting trees, no emission..? But it is not the fact. Strictly speaking internet is not green..!!
Amazed...? read more to know how...
When you send an email of 4.7 MB size, you are creating as much as green house gas as boiling a tea-kettle 17.5 times. That is an email of even 1MB size would be equal to emission of 19 grams of carbon dioxide (CO2). If that mail is copied to 10 people, its impact is 73 grams of CO2.
Suppose in a 100 people company where each employee sends an average of 33 emails a day and receives 58, the greenhouse gas emission linked to emails would be around 13.6 tons of CO2 per year. If each of these 100 employee sent 10 % less emails per year, they would save CO2 emissions equivalent to one round trip flight between Paris and New York!
The current amount of data storage across globe is around 1.2 zettabytes (one ZB is 10 raised to 21 MB). This requires equipment with a mass equivalent of 20% of island of Manhattan, New York City! Or an equivalent of all the US’ acedemic libraries multiplied by half a million. This data storage is expected to grow by 35 ZB by 2020.
30 percent of the input power is used in powering the chips, 30 percent of the energy entering a microprocessor is turned to heat, and that 123 billion kilowatt hour per year is how much electricity it takes just to keep the internet’s servers running.
Facebooking and Twittering
It is estimated that facebook users uploads over 1000 photos per second ie, 3 million photos per month. Think how much green house gas is released per month.
What all we can do...?
· Free up the memory space in your computer.
· Clean up the email box periodically.
· Limit the number of receipients of each email.
· Reduce the size of attachments.
· Enter the url address directly rather than using search engines like google and yahoo.
· Don’t leave your computer and accessories on overnight, not even on sleep mode, even though it don’t take much power.
· Laptops use 15-60 watts comparted to pc that consumes around 250 watts.
· Cut down power by doing more offline work than online.
· Facebooking and twittering release a lot of CO2. Talk more, Twitter less.
