Linux Power Consumption Analysis Tool

Here's a powerful power monitoring tool available from linux world.

PowerTop is a terminal-based linux program that shows power consumption and power analysis on Intel-based laptops and makes suggestions on how to extend battery lifetime.

Powertop site says:

Computer programs can make your computer use more power. PowerTOP is a Linux tool that helps you find those programs that are misbehaving while your computer is idle. The application that misbehaved the most was the Linux kernel. However, as of version 2.6.21, the Linux kernel went tickless, and no longer has a fixed 1000Hz timer tick. The result (in theory) is huge power savings because the CPU stays in low power mode for longer periods during system idle.

However... there are many things that can ruin the party, both inside the kernel and in userspace. PowerTOP combines various sources of information from the kernel into one convenient screen so that you can see how well your system is doing at saving power, and which components are the biggest problems.
