I always love when artists use their celebrity to do good for the community & good for the world and iHeartRadio Music Festival 2012 performers Linkin Park are doing just that. They recently met with the United Nations to lend their support for bringing modern, sustainable energy to the 1.3 billion people worldwide who lack access to basic electricity.  The initiative is called Power the World.  Watch the videos below to find out how you can do your part :-)
