You can use Google to search for terms such as "sustainability and "carbon footprint" and you will probably learn ways in which you can make a less harmful environmental impact. However, a new study conducted by a physicist from Harvard University which is posted on Telegraph shows that making two internet searches through Google produces about the same amount of carbon dioxide as boiling a kettle. A typical search is thought to generate about 7g of carbon dioxide. Boiling a kettle produces about 15g.
You may think twice about your favorite, quick method of gathering information. This article on Tech Crunch also sheds some light on the impact of Google searching and argues the benefits as well. I also appreciated the emphasis on the harm of other things besides Google, such as eating cheeseburgers - with carbon footprint of around 3,600 grams, and the recommendation to cut at least one out of your diet every week. I'll have to put that fact in my pocket for the next time we are deciding where to go for lunch.
