While the program may look like it only has settings easily found in your screen-saver menu, Local Cooling claims to save lots of energy. Enough energy to save a firm using 100 computers over $2000 a year. The clever program has a graphically friendly way to access energy saving system settings such as monitor turn-off times. It also lists the estimated power consumption of all hardware attached to the computer, including graphics cards, processors, and monitors. UniBlue made the application in an effort to cut energy costs in their own network. With a few tweaks, they made a free public version that you can download here.
