Software programs which claim to help you make your PC more energy efficient aren’t all that uncommon. In fact, we reviewed one not too long ago we weren’t overly impressed with. That being said, they do hold the potential to make a computer user’s habits more green, which is a good thing. Here’s another program we learned about recently via Red Ferret called Granola.
Granola is freeware, meaning it is free for your personal use. It runs in Linux and Windows. The developer describes it as making “computers more energy efficient without slowing them down. Granola is safe, easy to use, and allows your computer to operate with the performance of a Ferrari when speed counts but also with the efficiency of a Prius so you don’t waste energy.”
What Granola essentially does, according to the developer, is use “workload modeling and prediction algorithms” to determine when your computer is working so that the CPU can be properly adjusted to fuller or lesser speeds depending upon your need. The idea here is that in the “lower state” your the CPU consumes less energy, thus making your computer more efficient. This system optimization is automatic and reportedly does not compromise performance or availability. What can you expect out of it? Reportedly, lowering of “system energy use by 10-35% even when a system is 100% utilized.” Granola “also tracks the energy saved for use in estimating cost savings and carbon emission reductions.”
