Basically, LocalCooling scans your hardware and figures out how many watts your monitor, hard drives, CPU, graphics card, and other peripherals are probably using. Once the program has this estimate, it can also track how much energy you're saving by adjusting your power saving settings to do things like shut off yourmonitor, hard drives, or PC when you're not using them.
You can also create an account to track your energy savings against other users, or create teams to compete against other groups of LocalCooling users if you want to get all competitive about it.
