A survey conducted by Jonathan G. Koomey, a professor of civil and environmental engineering at Stanford University, USA, shows that electricity consumption of data centers around the world was contained by new electricity-saving technologies and "the recession of 2008," making they spent less electricity than expected by industry analysts.
In 2007, the National Security Agency U.S. Environmental predicted that increased demand for web services would cause the power consumption of datacenters doubled between the years 2005 and 2010. But according to Koomey's study, that number grew "only" 56% worldwide in the period and 36% in the U.S..
"Mainly because of the recession, but also because of some changes in how data centers are designed and operated, the growth of electricity consumption was lower than expected. And that's a great story, "Koomey said the New York Times.
Known for making investments in alternative energy sources, Google currently has 900,000 servers responsible for hosting your services search, Gmail and YouTube - that every minute of video takes 48 hours of its users.
According to the data, the giant web consumes 0.01% of global electricity, or 1% of the energy used by data centers around the world. Together, they use 1.5% of all electricity generated in the planet.
