These carbon emissions from electricity [...]]]> Results of research from Harvard University physicist Alex Wissner-Gross concluded each time the search engine work Google average yield 7 grams of carbon dioxide. This means that two searches had produced only 14 grams of carbon equivalent to that produced when someone a cup of boil water with an electric stove.

These carbon emissions from electricity consumption calculated the required computer users to energy expended Google’s data center that operates around the world. Use large energy means emissions of carbon dioxide is also considering the majority of power plants in use today are still based on fossil energy sources.

But Google denied the findings. In its official blog Google assessing the results of these calculations are too high. Google does not deny that the service but just suck the energy release equivalent to 0.2 grams of carbon for every search.

Google claims every time a search takes an average of 0.2 seconds. Access to the server each time the search for only the thousandth of a second scale. If Google average of 0.0003 kWh of energy needed for each search, the amount of carbon released is equivalent to 0.2 grams each time a user searches.

In 2007, Google established Climate Savers Computing Initiative, a non-profit consortium committed to suppress the use of energy at the consumer level by half from 2010 and reduce carbon dioxide emissions 54 million tons per year.

However, Wissner-Gross said services like Google still will suck enormous energy. He said to improve search engine capabilities, service providers must spend more energy. Recent research conducted analyst firm Gartner shows IT services currently contributes two percent of carbon emissions worldwide.
