Green Day, the rock trio that emerged from the California punk scene in the mid-1990s, quickly rose to superstardom among rebellious teenage fans and is widely credited with popularizing American punk music. The group has since solidified its place in American music history with three Grammies, most recently the 2006 Record of the Year award for the song "Boulevard of Broken Dreams." The band's members are now putting their pop-culture power to good use: In November, they signed on to NRDC's Move America Beyond Oil campaign, creating a partnership to mobilize music fans to demand clean, re-newable energy.
