Concern about environment and the global warming effect has finally reached software in the shape of this little tool, which tracks the power usage of your PC and optimizes it in order to save energy.
Local Cooling displays the amount of power used by the computer, monitor, hard drive and other peripherals on its window. You can then configure it to shutdown the monitor, spin down disks or even hibernate the computer after a certain period of time.
After using the program for some days, you'll be able to see, in terms of trees and fuel gallons, how much energy you have saved. You can also register in the author's website and compete against other users.
In all, a nice tool with a more than laudable aim, but still we missed some configuration options like the possibility to change measurement units.
