Yesterday April 22 is Earth Day. A day designed to inspire awareness and appreciation for the Earth's environment. Here I would like to share an application that I have been using to care our mother earth by monitoring energy efficiency in my computers. It is Edison by Verdiem. It is free but only available for Windows XP or Windows Vista platform. It might support more platform in the future. Currently my estimated annual savings is $71.62 with 693.31 kWh energy and 9.44.98 pounds CO2. I hope you will like it. Let's be green.
