Linux.. now power efficient

on Wednesday, August 22, 2007
Linux has always been a word of attraction to me and every time I look for any thing better to tell you about.And now I have got a great news . Linux programmers are making Linux computers more power efficient by creating a "tickless" kernel that abandons traditional time-keeping methods for a more power-friendly technique. Intel is also developing a power saver, called PowerTop, that makes it easier for users to know what software is needlessly keeping a computer's processor running.The tickless kernel is already making its way into the Linux mainstream. Intel programmer and longtime kernel developer Arjan van de Ven says a laptop running Linux now consumes 15 to
25 percent less power when idling than it did three months ago. Processors
consume a significant amount of power, frequently more than a 100-watt
light bulb, and heat reduction techniques such as air conditioning in data
centers and fans consume even more power. For some time now, processors
have been able to enter power-saving modes when a user sets the computer
to standby mode, but more can be done.
