With the introduction of the tickless kernel and PowerTop it has become possible to save significant amounts of power by reducing the number of times per second that the CPU has to do work. This in turn allows the CPU to sleep for longer periods of time and spend more time in deeper C-states.

However, most people do not know about powertop and, frankly, should not have to tweak their own system's power usage. Linux should save power by default, whenever it is possible to do so.

The concept of this project is simple:

Saving 3 Watts of power on millions of computers can make quite a difference.
