Ciberespaço Gasta Energia no Mundo Real
The amount of electricity consumed by computer servers has doubled in five years and will increase another 75 per cent by 2010, according to a report published on Thursday by an energy efficiency expert.
Jonathan Koomey, a consulting professor at Stanford University and scientist at America’s Lawrence Berkeley National Laboratory, says the world’s servers and their cooling infrastructure consumed as much power as that put out by 14 1,000-megawatt power stations in 2005.The total server electricity bill was about $7.3bn, of which the US made up $2.7bn.
Prof Koomey said servers and associated equipment represented about 1.2 per cent of US electricity consumption in 2005, comparable to the amount consumed by televisions.
