powertop

PowerTOP is a command line tool used for monitoring power consumption on Linux systems. It is specifically designed to analyze and optimize power usage of the CPU, GPU, hard drive, and other devices. By providing detailed information about power-hungry processes and hardware components, PowerTOP helps identify energy inefficiencies and suggests actions to reduce power consumption.

The tool presents a straightforward interface where users can view real-time power statistics, including the percentage of time spent in different power states and the estimated power consumption in Watts. It also displays a list of processes sorted by their power usage, making it easy to identify energy-intensive applications. Moreover, PowerTOP offers recommendations for power optimizations, such as adjusting CPU scaling settings, tweaking power management options, or disabling unnecessary services.

PowerTOP supports various resource monitoring features like CPU wakeups, software interrupts, battery discharge rate, and device activity tracking. It can generate reports in HTML format for further analysis and documentation. Additionally, PowerTOP can be run in calibration mode to simulate power savings and estimate the potential impact of optimizations.

Developed by Intel, PowerTOP is a valuable tool for both laptop and desktop users who want to reduce their power consumption, prolong battery life, and improve energy efficiency on their Linux systems. It serves as a handy utility for system administrators, power-conscious individuals, and organizations aiming to adopt greener computing practices.
