PowerTOP is a software utility designed to measure and explain a computer's electrical power consumption. It was released by Intel in 2007 under the GPLv.2 license.

PowerTOP analyzes the programs, device drivers, and kernel options running on a computer based on the Linux operating system, and estimates the power consumption resulting from their use. This information may be used to pinpoint software that results in excessive power use. Many open source and free software programs, such as Mozilla Firefox [1], have been patched to reduce their power consumption since the release of PowerTOP. This is particularly useful for laptop computer users who wish to prolong battery life, and datacenter operators, for whom electrical and cooling costs are a major expenditure. Latest Version: 1.9 (November, 2007)
