How Internet Affects World Environment 

 

 

 We all know that Internet has now become one of the important element in all our life. On Earth Day we will find out how Internet is affecting our World Environment? Is it possible that our tech gadgets and online internet activities themselves might be harming the planet or earth in someway? We know that the data centers that power our favorite applications and websites are far from green, although Google and Facebook are attempting to change that, both in the kinds of energy we use and how much energy is needed.

Several recent studies and articles have shown that a simple Google search can result in 1-10 grams of CO2 emissions. With over 200 million internet searches per day (2006) in the US alone, we are looking at up to 2000 tons of greenhouse gas emissions per day.

Last fall Google decided to work with Greenhouse Gas Services, a GE and AES joint venture, to capture and destroy landfill methane emissions from a North Carolina landfill. This reduction in greenhouse gas emissions helps to lessen net emissions and "offsets" some of Google's own "carbon footprint." Unfortunately the 2000 ton figure refers only to internet searches, but what about other uses for the internet?

Computers create 40-80 grams of greenhouse gas emissions per hour through their electricity use (depending on electricity source and computer type), so the aggregated greenhouse gas emissions just from computers is quite sizable, nevermind the servers and fiber optic lines. Sources say that the internet accounts for 3 percent of US electricity consumption and 2 percent of global CO2 emissions.

So, what can be done to reduce the environmental impact of the internet? 

Many of the companies involved in building and operating the data centers, the brains of the internet, have been working on improving data center efficiency for several years. Processors have increased in computing power, while decreasing in energy demand, and new ways have been developed to keep massive server farms cool. Server farms can be located near hydroelectric facilities or other sources of renewable energy and the can be built in the arctic circle to take advantage of natural cooling.
On an individual level it is important to simply be aware that using the internet is not "carbon neutral" and don't leave your computer on when you aren't using it.
