Hoping an inclusive, flexible approach will draw support, Sen. Jeff Bingaman (D-N.M.) recently introduced the Clean Energy Standard Act of 2012.
The bill will will attempt to push large retail utilities to get their electricity from cleaner - but not necessarily renewable - sources.
Bingaman (D-N.M.), chairman of the Senate Energy and Natural Resources Committee, had tried before to mirror state renewable portfolio standards with a federal renewable electricity standard, but his legislation never gained real traction.
