PowerTOP is a software utility designed to measure, explain and minimise a computer's electrical power consumption.^[1] It was released by Intel in 2007 under the GPLv2 license. It works for Intel, AMD, ARM and UltraSPARC processors.

PowerTOP analyzes the programs, device drivers, and kernel options running on a computer based on the Linux and Solaris operating systems, and estimates the power consumption resulting from their use.^[1] This information may be used to pinpoint software that results in excessive power use. This is particularly useful for laptop computer users who wish to prolong battery life, and data center operators, for whom electrical and cooling costs are a major expenditure.
