In January my husband came home from work and shared a blurb he heard on the radio. Old news now, but still relevant. The station stated that, ”doing a single search through Google uses as much energy as boiling a cup of tea”. I thought it was interesting so I did an energy consuming search to find details. Google is my search engine of choice as well as millions of other Internet users. Naturally they were at the top of the hit list in the media coverage.
According to an article in Times Online called, “Revealed: the environmental impact of Google searches, New research lifts lid on links between CO2 emissions and Internet searches”, a comparative to other CO2 emissions makes it sound like we are headed for global disaster by Internet use. “A recent report by Gartner, the industry analysts, said the global IT industry generated as much greenhouse gas as the world’s airlines – about 2% of global CO2 emissions.”
The article took it a step further to demonize the use of Internet sites with graphics. Alex Wissner-Gross, a Harvard University Physicist, ”research indicates that viewing a simple web page generates about 0.02g of CO2 per second. This rises tenfold to about 0.2g of CO2 a second when viewing a website with complex images, animations or videos”. Which means that anyone with a site riddled with graphics are making CO2 emissions worse by the second.
To add more fuel to the CO2 emissions research John Buckley, a British environmental consultant, made further claims about Google searches but worse is this claim, “simply running a PC generates between 40g and 80g per hour”. If you are like me you use your computer every day for at least 8 hours, and do numerous searches.
To cut back on computer use, I’d have to waste gas going 30 miles each way to spend the entire day at a library. Which after using a CO2 emission calculator is putting 73.365lbs of CO2 emission into the atmosphere. Hmmm… the Internet consumptions seems to pale in comparison. Based on the above mentioned numbers I used the highest measurements for my personal use which is 80g/hr for 8 hours equals 640g just to run my PC. Using .2g a second for 4 hours of search and graphic websites ,which is a high estimate, equals 2280g. So at most, I am emitting 7.7533lbs a day. I’m actually saving the environment 65.6117lbs a day by staying at home using my computer vs. taking a trip to the closest library.
Writing Prompt: Do your own comparison of personal emissions. Using the conversion site listed below measure your gas emissions. One gallon of gasoline is equivalent to 19.564lbs of CO2 emissions. In case you need a refresher of grams to pounds conversion it is 454g = 1lb. When you’ve finished your calculations write an article based on your findings. Also suggest ways people can save energy when using their PC and doing Internet searches. For example: You might advise webmasters to reduce the use of graphics on their websites.
