Green Pulse is an efficient program that controls energy usage of your computer after you stop using it. It works without human intervention, so you don't have to change your habits. Green Pulse turns off your monitor when it detects lower activity, and turns off the computer after you stop using it. Since a home computer uses a lot of electric energy over a period, shutting it down regularly decreases the electricity bill noticeably. Green Pulse will pay for its self within a few months by reducing your electricity costs. The electrical power that powers your computer needs to be produced, and the production process pollutes the environment. If you use Green Pulse to save the energy, you also help in reducing the carbon dioxide (CO2) emissions, which helps the environment.
