Southern California Edison has launched one of the most ambitious solar initiatives yet. It involves using the roofs of commercial buildings to develop renewable energy resources. Building owners get paid to host the solar arrays on their rooftops, and the utility takes all the risk. Where else is this kind of program happening?

Denis interviews the corporate sustainability executive for AMB Property Corporation, who just joined SCE's new program. (podcast)
