Whether you are environmentally conscious or just looking to save some cash, the rising prices of energy have everybody looking to cut back on costs. If you've ever wondered how much power your computer consumes, there's a free power management tool called Local Cooling here to help you out.

The goals of the Local Cooling project include cutting energy costs and reduction of greenhouse emissions, and the utility shows detailed results of how much power you've saved before and after installing the software. They have a goal of creating a community of 100,000,000 PC users who want to help reduce CO2 gas emissions.

You don't have apply any settings, but it's at least interesting to see what's your computer energy consumption.
