Download and install this free PC energy management tool and reduce significantly your electricity bills.

PCs can consume as much as 10 percent of a home's energy bill and give off as much carbon dioxide as a family car. Even when a PC's screen saver kicks on, the machine can still consume between 100 watts and 250 watts.

The Edison software doesn't completely shut a computer off but rather moves it to a "suspend" state, which uses less energy. Users can also schedule to shut down the screen and hard drive before going into suspend mode.

The tool lets users have work and home settings. It has a read-out of how much electricity you are saving, also translated into reductions in carbon dioxide emissions and dollar savings.

Estimates will vary widely, depending on electricity rates and type of computer, but Verdiem says the average savings is 410 kilowatt hours a year, or $36.50.
