Granola is an intelligent software power management solution for x86 servers, laptops, and PCs running Linux and Microsoft Windows.

Granola automatically optimizes a system to use energy more efficiently without compromising performance or availability. The Granola Power Management Daemon when installed on a server, laptop, or PC, matches the energy consumed by the system to the load on the system automatically.

Granola typically lowers total 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.
