POSTER: computer news   ||   POWER UNITS EFFICIENCY	DATE:2007-06-13
The passed exhibition computex 2007 designated important tendency in power units production  : many powerful models attempt to pass the certification of 80% + EFFICIENCY . Effective electric power is important for electricity reduction and also from the global ecological side. The stations generating electric power push in the atmosphere a lot of dioxide carbon . Scientists many time talked about this serious problem in last several years, So computers producers purpose to decrease the energy consumption of computer systems . Most computers lose up to 50% energy in the heat form . This energy is dissipated in most case in idle state . In servers such losses compose 30%. In regime idle , computers also consume sufficient amount of electric power. The producers orientation to the energy-saving technologies, was able to increase the EFFICIENCY in power-supply systems to level higher than 90%. Actually, the energy effectiveness of Google servers lies in the range from 90% to 93%. In order to bring THE computer EFFICIENCY to 90%, it is now necessary to increase its cost by $20, in the case of server additional expenditures will be $30. Dell company  proposes the modification of servers with increased energy effectiveness, Such server will be $100 more expensive, but these expenditures are compensated after a year operation. The mass production of energy-saving components will allow to reduce the difference in cost between equipment. After beginning their propagation in USA, Europe and Japan, energy-saving components will gradually obtain popularity also on developing markets countries as China. Initiative-group calculated, that if  to 2010 the majority of computers and servers in the world will have  power-supply systems EFFICIENCY not lower than 90%, then in this year it will be possible to save 71,6 billion kW electric power. This will allow to decrease the ejections of dioxide carbon to 54 mln. tons. ..... Related Products :
