It is hard to imagine the energy you are using when you sit in front of your computer or laptop. Most people think only of the electricity used to power their machine.

A typical Google search generates about 7g of CO2. Compare this to boiling a kettle which generates about 15g. Like all search engines, Google operates huge data centres around the world. Banks of servers storing billions of web pages consume a great deal of power therefore a search and all other internet use has a definite environmental impact.

Alex Wissner-Gross, a Harvard University physicist has studied the environmental impact of computing. His 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.

Nicholas Carr, author of The Big Switch, Rewiring the World, has calculated that maintaining a character (known as an avatar) in the Second Life virtual reality game, requires 1,752 kilowatt hours of electricity per year. That is almost as much used by the average Brazilian.
